Organization, Consolidation and Presentation of Financial Statements Disclosure [Text Block]	Note 1. Description of Business and Basis of Presentation Overview Lighting Science Group Corporation (the “Company”) was incorporated in Delaware in 1988 and designs, develops and markets general illumination products that exclusively use light emitting diodes (“LEDs”) as their light source. The Company’s product portfolio includes LED-based retrofit lamps (replacement bulbs) used in existing light fixtures and sockets as well as purpose built LED-based luminaires (light fixtures) for many common indoor and outdoor residential, commercial, industrial and public infrastructure lighting applications. The Company assembles and manufactures its products through its contract manufacturers in Asia. Basis of Financial Statement Presentation The accompanying unaudited condensed consolidated financial statements are presented pursuant to the rules and regulations of the United States Securities and Exchange Commission (the “SEC”) in accordance with the disclosure requirements for the quarterly report on Form 10-Q and therefore do not include all of the information and footnotes required by generally accepted accounting principles in the United States of America (“GAAP”) for complete financial statements. In the opinion of management, the unaudited condensed consolidated financial statements reflect all adjustments (consisting of normal recurring adjustments) necessary to fairly state the results for the interim periods presented. The condensed consolidated balance sheet as of December 31, 2015 is derived from the Company’s audited financial statements. Operating results for the three months ended March 31, 2016 are not necessarily indicative of the results of the Company that may be expected for the year ending December 31, 2016. These unaudited condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements as of and for the year ended December 31, 2015 and notes thereto included in the Company’s Annual Report on Form 10-K filed with the SEC on April 14, 2016. The condensed consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All significant intercompany accounts and transactions have been eliminated in the accompanying consolidated financial statements.

Notes to Financial Statements
Significant Accounting Policies [Text Block]	Note 2. Summary of Significant Accounting Policies Use of Estimates The preparation of the accompanying consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions about future events. These estimates and the underlying assumptions affect the amounts of assets and liabilities reported, disclosures about contingent assets and liabilities, and reported amounts of revenue and expenses. Such estimates include the valuation of accounts receivable, inventories, intangible assets and other long-lived assets, legal contingencies, and customer incentives, among others. These estimates and assumptions are based on management’s best estimates and judgment. Management evaluates its estimates and assumptions on an on -going basis using historical experience and other factors, including the current economic environment, which management believes to be reasonable under the circumstances. The Company adjusts such estimates and assumptions when facts and circumstances dictate. Illiquid credit markets, volatile equity, foreign currency and energy markets and declines in consumer spending have combined to increase the uncertainty inherent in such estimates and assumptions. As future events and their effects cannot be determined with precision, actual results could differ significantly from these estimates. Changes in those estimates resulting from continuing changes in the economic environment will be reflected in the financial statements in future periods. Restricted Cash As of March 31, 2016 and December 31, 2015, as required by the Company’s five-year term loan (as amended from time to time, the “Medley Term Loan”) with Medley Capital Corporation (“Medley”), the Company was required to maintain a minimum restricted cash balance of $3.0 million to collateralize the Medley Term Loan. Changes in the restricted cash balance were reflected as a financing activity in the consolidated statements of cash flows. Accounts Receivable The Company records accounts receivable at the invoiced amount when its products are shipped to customers or upon the completion of specific milestone billing requirements. The Company’s receivable balance is recorded net of allowances for amounts not expected to be collected from customers. This allowance for doubtful accounts is the Company’s best estimate of probable credit losses in the Company’s existing accounts receivable. Estimates used in determining the allowance for doubtful accounts are based on historical collection experience, aging of receivables and known collectability issues. The Company writes off accounts receivable when it becomes apparent, based upon age or customer circumstances that such amounts will not be collected. The Company reviews its allowance for doubtful accounts on a quarterly basis. Recovery of bad debt amounts previously written off is recorded as a reduction of bad debt expense in the period the payment is collected. Generally, the Company does not require collateral for its accounts receivable and does not regularly charge interest on past due amounts. As of March 31, 2016 and December 31, 2015, the Company’s allowance for doubtful accounts was $470,000 and $475,000, respectively. As of March 31, 2016 and December 31, 2015, $6.9 million and $4.2 million, respectively, of eligible accounts receivable were pledged as collateral for the three-year asset based revolving credit facility (as amended from time to time, the “FCC ABL”) entered into on April 25, 2014 with FCC, LLC d/b/a First Capital (“First Capital”). First Capital sold the FCC ABL to ACF FinCo I LP (“Ares”) in May 2015, and the FCC ABL is hereinafter referred to as the “Ares ABL”. Revenue Recognition The Company records revenue when its products are shipped and title passes to customers. When sales of products are subject to certain customer acceptance terms, revenue from such sales is recognized once these terms have been met. The Company also provides its customers with limited rights of return for non-conforming shipments or product warranty claims. Product Warranties The Company generally provides a five-year limited warranty covering defective materials and workmanship of its products and such warranty may require the Company to repair, replace or reimburse the purchaser for the purchase price of the product. The estimated costs related to warranties are accrued at the time products are sold based on various factors, including the Company’s stated warranty policies and practices, the historical frequency of claims and the cost to repair or replace its products under warranty. The following table summarizes changes in the warranty provision for the three months ended March 31, 2016: Warranty provision as of December 31, 2015 $ 3,285,424 Additions to provision 233,757 Less warranty costs (309,140 ) Warranty provision as of March 31, 2016 $ 3,210,041 Fair Value Measurements The Company utilizes valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible. The Company determines fair value based on assumptions that market participants would use in pricing an asset or liability in the principal or most advantageous market. When considering market participant assumptions in fair value measurements, the following fair value hierarchy distinguishes between observable and unobservable inputs, which are categorized in one of the following levels: • Level 1 Inputs: Unadjusted quoted prices in active markets for identical assets or liabilities accessible to the reporting entity at the measurement date. • Level 2 Inputs: Other than quoted prices included in Level 1 inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the asset or liability. • Level 3 Inputs: Unobservable inputs for the asset or liability used to measure fair value to the extent that observable inputs are not available, thereby allowing for situations in which there is little, if any, market activity for the asset or liability at measurement date. Fair Value of Financial Instruments Cash and cash equivalents, accounts receivable, accounts payable, amounts due under lines of credit and other short term borrowings, accrued expenses and note payable are carried at amounts that approximate their fair value due to the short-term maturity of these instruments and/or variable, market driven interest rates. The liabilities under derivative contracts, which represent warrants to purchase shares of the Company’s common stock, par value $0.001 per share (the “Common Stock”) were initially recorded at fair value and subsequently reflected at their fair value at the end of each reporting period. The fair value of the warrant issued to The Home Depot, Inc. (the “THD Warrant”) is determined using the Monte Carlo valuation method and will be adjusted at each reporting date until the underlying shares have been earned for each year . Such adjustments will be recorded as a reduction in the related revenue (sales incentive) from The Home Depot, Inc . (“The Home Depot”). Once a portion of the THD Warrant vests it is recorded at its fair value at the end of each subsequent reporting period. Recently Adopted Accounting Pronouncements In April 2015, the FASB issued ASU 2015-03 that intends to simplify the presentation of debt issuance costs. Debt issuance costs related to a recognized debt liability will be presented on the balance sheet as a direct deduction from the debt liability, similar to the presentation of debt discounts. ASU 2015-03 is effective for public business entities for fiscal years beginning after December 15, 2015, and interim periods within those fiscal years. Early adoption is permitted. The cost of issuing debt will no longer be recorded as a separate asset, except when incurred before receipt of the funding from the associated debt liability. The Company retrospectively adopted ASU 2015-03 as of January 1, 2016. The adoption of this guidance did not have a material impact on the condensed consolidated financial statements or notes to condensed consolidated financial statements. In November 2015, the FASB issued ASU No 2015-17 to simplify the presentation of deferred income taxes by requiring that deferred tax assets and liabilities be classified as non-current in the balance sheet. The new guidance is effective for the annual period ending after December 15, 2016, and interim periods thereafter, with early adoption permitted. The Company retrospectively adopted ASU 2015-17 as of January 1, 2016. The adoption of this guidance did not have a material impact on the condensed consolidated financial statements or notes to condensed consolidated financial statements. Recently Issued Accounting Pronouncements Not Yet Adopted In May 2014, the Financial Accounting Standards Board (the “FASB”) issued ASU 2014-09, which will replace most existing revenue recognition guidance in U.S. generally accepted accounting principles and is intended to improve and converge the financial reporting requirements for revenue from contracts with customers with International Financial Reporting Standards (“IFRS”). The core principle of ASU 2014-09 is that an entity should recognize revenue for the transfer of goods or services equal to the amount that it expects to be entitled to receive for those goods or services. ASU 2014-09 also requires additional disclosures about the nature, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments. ASU 2014-09 allows for both retrospective and prospective methods of adoption and is effective for periods beginning after December 15, 2016. In August 2015, the FASB issued ASU 2015-14 which provides a one-year deferral of the revenue recognition standard’s effective date. Public business entities are required to apply the revenue recognition standard to annual reporting periods beginning after December 15, 2017, and interim periods within those annual periods. Early application is permitted but not before the original effective date for public business entities (annual reporting periods beginning after December 15, 2016). The option to use either a retrospective or cumulative-effective transition method did not change. The Company is currently evaluating the method of adoption and the impact that the adoption of ASU 2014-09 will have on its consolidated financial statements. In August 2014, the FASB issued ASU 2014-15 requiring management to perform interim and annual assessments of an entity’s ability to continue as a going concern within one year of the date the financial statements are issued. The standard also provides guidance on determining when and how to disclose going-concern uncertainties in the financial statements. The new guidance is effective for the annual period ending after December 15, 2016, and interim periods thereafter, with early adoption permitted. The Company is currently evaluating the method of adoption and the impact that the adoption of ASU 2014-15 will have on its consolidated financial statements. In July 2015, the FASB issued ASU 2015-11, “Inventory (Topic 330).” This update requires an entity to measure inventory within the scope of the update at the lower of cost and net realizable value. This update is effective for financial statements issued for fiscal years beginning after December 15, 2016, and interim periods within those fiscal years. The Company is currently evaluating the method of adoption and the impact that the adoption of ASU 2015-11 will have on its consolidated financial statements. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842). ASU 2016-02 introduces a lessee model that brings most leases on the balance sheet. The new standard also aligns many of the underlying principles of the new lessor model with those in ASC 606, the FASB's new revenue recognition standard (e.g., those related to evaluating when profit can be recognized). Furthermore, ASU 2016-02 addresses other concerns related to the current leases model. For example, ASU 2016-02 eliminates the requirement in current U.S. GAAP for an entity to use bright-line tests in determining lease classification. The standard also requires lessors to increase the transparency of their exposure to changes in value of their residual assets and how they manage that exposure. The Company is required to adopt ASU 2016-02 for periods beginning after December 15, 2018, including interim periods, with early adoption permitted. The Company is currently evaluating the method of adoption and the impact that the adoption of ASU 2016-02 will have on its consolidated financial statements. Reclassification Certain prior period amounts in the accompanying consolidated financial statements have been reclassified to conform to the current year presentation. These reclassifications had no effect on previously reported net loss or stockholders’ deficit.

Liquidity and Capital Resources [Text Block]	Note 3. Liquidity and Capital Resources As shown in the condensed consolidated financial statements, the Company has experienced significant historical net losses as well as negative cash flows from operations since its inception, resulting in an accumulated deficit of $832.1 million and stockholders’ deficit of $558.7 million as of March 31, 2016. As of March 31, 2016, the Company had cash and cash equivalents of $1.7 million and an additional $3.0 million in restricted cash subject to a cash collateral dominion agreement pursuant to the Medley Term Loan. The Company’s cash expenditures primarily relate to procurement of inventory, payment of salaries, employee benefits and other operating costs. The Company’s primary sources of liquidity have historically been borrowings from Ares under the Ares ABL, from Medley under the Medley Term Loan and from other previous lenders, as well as sales of Common Stock and Convertible Preferred Stock (as defined below) to, and short-term loans from, affiliates of Pegasus Capital Advisors, L.P. (“Pegasus Capital”), including Pegasus Partners IV, L.P. (“Pegasus Fund IV”), LSGC Holdings, LLC (“LSGC Holdings”), LSGC Holdings II, LLC (“Holdings II”), LSGC Holdings III, LLC (“Holdings III”) and PCA LSG Holdings, LLC (“PCA Holdings” and collectively with Pegasus Capital, Pegasus Fund IV, LSGC Holdings, Holdings II, Holdings III and their affiliates, “Pegasus”). Pegasus is the Company’s controlling stockholder. While Pegasus has led a majority of the Company’s capital raises, certain offerings of Convertible Preferred Stock also involved and/or were led by parties other than Pegasus. The Company obtained the five-year, $30.5 million Medley Term Loan from Medley on February 19, 2014, pursuant to a Term Loan Agreement (as amended from time to time the “Medley Loan Agreement”). Pursuant to the Medley Loan Agreement, the Company is required to achieve a minimum quarterly fixed charge coverage ratio for the preceding 12-month period and to maintain certain minimum EBITDA levels. In connection with the Medley Term Loan, the Company issued a warrant to purchase 5,000,000 shares of Common Stock to each of Medley and Medley Opportunity Fund II LP (the “Medley Warrants”). The Company also obtained a three-year revolving credit facility with a maximum line amount of $22.5 million from Ares on April 25, 2014, pursuant to a Loan and Security Agreement (as amended from time to time, the “Ares ABL Agreement”). As of March 31, 2016, the Company had $11.0 million in borrowings outstanding under the Ares ABL Agreement and additional borrowing capacity of $2.7 million. The maximum borrowing capacity under the Ares ABL Agreement is based on a formula of eligible accounts receivable and inventory. The Ares ABL Agreement also requires the Company to achieve a minimum quarterly fixed charge coverage ratio for the preceding 12-month period. On January 30, 2015 , September 11, 2015 and February 23, 2016, the Company issued 11,525 , 10,000 and 3,000 units of its securities (“Series J Securities”), respectively, to Holdings III. On September 30, 2015, the Company issued 62 Series J Securities to certain existing preferred stockholders upon exercise of their preemptive rights under the certificates of designation governing the Convertible Preferred Stock. In each case, the Series J Securities were issued at a purchase price of $1,000 per Series J Security, and the Company received aggregate gross proceeds of approximately $24.6 million in connection with these issuances. Each Series J Security consists of (i) one share of Series J Convertible Preferred Stock (“Series J Preferred Stock”) and (ii) a warrant to purchase 2,650 shares of Common Stock, at an exercise price of $0.001 per share (the “Series J Warrants”). The Company continues to face challenges in its efforts to achieve profitability and positive cash flows from operations. The Company’s ability to continue to meet its obligations in the ordinary course of business is dependent upon establishing profitable operations, which may be supplemented by any additional funds that the Company may raise through public or private financing or increased borrowing capacity. In 2015 , the Company’s largest customer, The Home Depot, performed a periodic product line review relating to its entire private label LED lighting product offering. Following the line review, the Company entered into a new supplier buying agreement with The Home Depot, which is expected to go into full effect in the second quarter of 2016. Pursuant to this new supplier buying agreement, The Home Depot has elected to purchase certain products previously supplied by the Company directly from overseas suppliers. Such products represented a significant percentage of the Company’s sales to The Home Depot in 2015 and 2014. The Company was, however, selected to supply certain new products to The Home Depot and will continue to supply certain other products to The Home Depot under its prior agreement. In addition, the terms of the new supplier buying agreement with The Home Depot permit the Company to pursue opportunities to sell products to specified big box and other retailers, which was prohibited under its prior agreement. Notwithstanding the new supplier buying agreement, as was the case under the Company’s prior agreement with The Home Depot, The Home Depot is not required to purchase any minimum amount of products from the Company. As a result of the line review, the Company expects 2016 sales to The Home Depot and, as a result, revenue, to be significantly less than what it was in 2015. However, because the Company cannot reasonably estimate the extent to which such reduced revenue may be offset by sales of the new products to The Home Depot or by any potential new sales to other retailers, the Company cannot determine at this time the overall impact that the results of The Home Depot line review will have on the Company’s financial condition and operations in the future. As a result of the Company’s historical losses, the Company believes it will likely need to raise additional capital to fund its operations. Sources of additional capital may not be available in an amount or on terms that are acceptable to the Company, if at all. The Company’s complex capital structure, including its obligations to the holders of the outstanding shares of its Convertible Preferred Stock and the new series of preferred stock designated as Series K (“Series K Preferred Stock”), may make it more difficult to raise additional capital from new or existing investors or lenders. If the Company is not able to raise such additional capital, the Company may need to restructure or refinance its existing obligations, which restructuring or refinancing would require the consent and cooperation of the Company’s creditors and certain stockholders. In such event, the Company may not be able to complete a restructuring or refinancing on terms that are acceptable to the Company, if at all. If the Company is unable to obtain sufficient capital when needed, the Company’s business, compliance with its credit facilities and future prospects may be adversely affected. Pegasus has committed to provide financial support to the Company of up to $5.25 million, as needed, to fund its operations and debt service requirements through April 2017. The amount of this commitment will be reduced by the amount of any capital provided by other parties (except for draws under the Ares ABL) that is not repayable by the Company on or before April 14, 2017. Such commitment, which in no way amounts to a guarantee of the Company’s obligations, may be provided through a variety of mechanisms, which may or may not be similar to those previously employed. Furthermore, in exchange for such support, Pegasus, as the Company’s controlling stockholder, may request that the Company take certain actions related to operations, capital structure or otherwise, which, if accepted, could have a negative effect on its business and results of operations. In addition, Pegasus may seek other terms and consideration that would require, and may not receive, approval by the independent committee of the Company’s board of directors. Management believes that, subject to certain conditions, the Company will have sufficient capital to fund its operations for the next 12 months. Such conditions include, among other things, (1) maintaining the Company’s lower cost structure implemented over the last three years, (2) replacing a significant portion of the decline in revenue anticipated as a result of The Home Depot’s line review and (3) if necessary, Pegasus fulfilling its commitment as described above. RW LSG Holdings LLC (“Riverwood Holdings”) and Pegasus each have the right to cause the Company to redeem their shares of Series H Convertible Preferred Stock (“Series H Preferred Stock”) and Series I Convertible Preferred Stock (“Series I Preferred Stock” and, collectively with the Series H Preferred Stock and the Series J Preferred Stock, the “Convertible Preferred Stock”), respectively, at any time on or after March 27, 2017. If either Riverwood Holdings or Pegasus elects to cause the Company to redeem its shares of Series H Preferred Stock or Series I Preferred Stock, all other holders of the applicable series will similarly have the right to request the redemption of their shares of Convertible Preferred Stock. In addition, Portman Limited (“Portman”) and affiliates of Zouk Holdings Limited, acting together, have a contractual right to require the Company to redeem their respective shares of Series H Preferred Stock on or after March 27, 2017, subject to certain conditions and limitations. The Company is also required to redeem the outstanding shares of its Series J Preferred Stock (a) subject to certain limited exceptions, immediately prior to the redemption of the Series H Preferred Stock, Series I Preferred Stock or any other security that ranks junior to the Series J Preferred Stock and (b) on November 14, 2019, at the election of the holders of Series J Preferred Stock (a “Special Redemption”). Holders of Convertible Preferred Stock would also have the right to require the Company to redeem such shares upon the uncured material breach of the Company’s obligations under its outstanding indebtedness or the uncured material breach of the terms of the certificates of designation governing the Convertible Preferred Stock. Depending on whether the Appeal Bond (as defined below) has been drawn or fully released, the Series K Certificate of Designation requires us to redeem the outstanding shares of Series K Preferred Stock in the event of a liquidation, dissolution or winding up of the Company or an earlier change of control or “junior security redemption,” which includes events triggering a redemption of the outstanding shares of Convertible Preferred Stock. As of March 31, 2016, in the event the Company was required to redeem all of its outstanding shares of Convertible Preferred Stock and Series K Preferred Stock (collectively, the “Preferred Stock”), the Company’s maximum payment obligation would have been $538.2 million. The Company would be required to repay its outstanding obligations under the Medley Term Loan and the Ares ABL prior to the redemption of any shares of Preferred Stock. As of March 31, 2016, the Company had $38.1 million of aggregate borrowings outstanding under these credit facilities that it would be required to repay prior to any redemption of Preferred Stock . Any redemption of the Preferred Stock would be limited to funds legally available therefor under Delaware law. The certificates of designation governing the Preferred Stock provide that if there is not a sufficient amount of cash or surplus available to pay for a redemption of Preferred Stock, then the redemption must be paid out of the remaining assets of the Company. In addition, the certificates of designation governing the Preferred Stock provide that the Company is not permitted or required to redeem any shares of Preferred Stock for so long as such redemption would result in an event of default under the Company’s credit facilities. As of March 31, 2016, based solely on a review of the Company’s balance sheet, the Company did not have legally available funds under Delaware law to satisfy a redemption of its Preferred Stock. In addition, based solely on the Company’s projected balance sheet as of March 27, 2017, the Company does not believe that it will have legally available funds on or before March 27, 2017 to satisfy any such redemption of the Preferred Stock. The certificate of designation governing the Series H Preferred Stock also provides that upon the occurrence of a “control event,” the Company must take any and all actions required and permitted to fix the size of its board of directors to a size that would permit Riverwood Holdings (as the primary investor of the Series H Preferred Stock) to appoint a majority of the directors to the board until the Company satisfies or otherwise cures the obligations giving rise to the control event. A control event occurs if, among other things, Riverwood Holdings exercises its optional redemption right under the certificate of designation governing the Series H Preferred Stock and the Company is unable to redeem Riverwood Holdings’ shares of Series H Preferred Stock. If Riverwood Holdings were to exercise its optional redemption right and a control event were to occur, Riverwood Holdings could take control of the board of directors. The certificate of designation governing the Series J Preferred Stock provides that if the Company does not have sufficient capital available to redeem the Series J Preferred Stock in connection with a Special Redemption of the Series J Preferred Stock, the Company will be required to issue a non-interest bearing note or notes (payable 180 days after issuance) in the principal amount of the liquidation amount of any shares of Series J Preferred Stock not redeemed by the Company in connection with such Special Redemption, subject to certain limitations imposed by Delaware law governing distributions to stockholders. As discussed further in Note 14, one of the Company’s stockholders, Geveran Investments Limited (“Geveran”), filed a lawsuit against the Company and certain other defendants seeking, among other things, rescissionary damages in connection with its $25.0 million investment in the Company. On November 30, 2015, the Circuit Court of the Ninth Judicial Circuit in and for Orange County, Florida , the court presiding over the lawsuit, entered an Order Granting Plaintiff’s Motion for Partial Summary Judgment Under its First Cause of Action for Violation of the Florida Securities and Investment Protection Act (the “Summary Judgment Order”). Accordingly, the Company, with the assistance of Pegasus Fund IV, posted an appeal bond in the amount of $20.1 million (the “Appeal Bond”) in support of the Company’s appeal of the Summary Judgment Order. As contemplated by the Preferred Stock Subscription and Support Agreement dated September 11, 2015 (the “Subscription and Support Agreement”) among the Company, Holdings III and Pegasus Partners IV, L.P. (“Pegasus Fund IV”), Pegasus Fund IV agreed to assist the Company in securing the Appeal Bond on the terms set forth in a General Indemnity Agreement and related side letter to be entered into by and among the Company, Pegasus Fund IV and the issuer of the Appeal Bond (the “Appeal Bond Agreements”). The Company executed the Appeal Bond Agreements with Pegasus Fund IV and the issuer of the Appeal Bond on December 4, 2015, and on December 7, 2015, in consideration of Pegasus Fund IV’s entry into the Appeal Bond Agreements and as security for the potential payments to be made to the issuer of the Appeal Bond for draws upon the Appeal Bond, the Company issued 20,106.03 units of its securities (the “Series K Securities”) to Pegasus Fund IV, with each Series K Security consisting of (a) one share of Series K Preferred Stock and (b) a warrant to purchase 735 shares of Common Stock. The number of Series K Securities issued to Pegasus Fund IV was determined based on the quotient obtained by dividing (x) the aggregate amount of the bonds, undertakings, guarantees and/or contractual obligations underlying Pegasus Fund IV’s initial commitment with respect to the Appeal Bond by (y) $1,000. Although the Company cannot predict the ultimate outcome of this lawsuit, it believes the court’s summary judgment award in favor of Geveran was in error and that it has strong defenses against Geveran’s claims. However, in the event that the Company is not successful on appeal, it could be liable for the full amount of Geveran’s $25.0 million investment, as well as interest, attorneys’ fees and court costs. Accordingly, the Summary Judgment Order and the Appeal Bond could have a material adverse effect on the Company’s liquidity and its ability to raise capital in the future.

Earnings Per Share [Text Block]	Note 10: Earnings (Loss) Per Share In 2012, the Company determined that two classes of Common Stock had been established for financial reporting purposes only, with Common Stock attributable to controlling stockholders representing shares beneficially owned and controlled by Pegasus and the Common Stock attributable to noncontrolling stockholders representing the minority interest stockholders. For the three months ended March 31, 2016 and 2015, the Company computed net loss per share of noncontrolling stockholders and controlling stockholders of Common Stock using the two-class method. Net loss from operations is initially allocated based on the underlying common shares held by controlling and noncontrolling stockholders. The allocation of the net losses attributable to the Common Stock attributable to controlling stockholders is then reduced by the amount of the deemed dividends. The following table sets forth the computation of basic and diluted net loss per share of Common Stock: For the Three Months Ended March 31, 2016 2015 Controlling Stockholders Noncontrolling Stockholders Controlling Stockholders Noncontrolling Stockholders Basic and diluted net income (loss) per share: Net loss attributable to common stock $ (3,632,930 ) $ (1,087,318 ) $ (10,154,538 ) $ (3,446,552 ) Deemed dividends related to the Series J Preferred Stock attributable to all shareholders (2,930,787 ) (877,170 ) (11,421,641 ) (3,876,619 ) Undistributed net loss $ (6,563,717 ) $ (1,964,488 ) $ (21,576,179 ) $ (7,323,171 ) Basic and diluted weighted average number of common shares outstanding 327,637,170 98,060,244 287,758,558 97,668,138 Basic and diluted net loss per common share $ (0.02 ) $ (0.02 ) $ (0.07 ) $ (0.07 ) Basic earnings per share is computed by dividing net loss available to common stockholders by the weighted average number of common shares outstanding for the applicable period. The Series J Warrants have an exercise price of $0.001 per share of Common Stock, and are included in the weighted average number of shares of Common Stock outstanding as there are no conditions that must be satisfied before such warrant may be exercised into the shares of Common Stock underlying such warrants. Diluted earnings per share is computed in the same manner as basic earnings per share except the number of shares is increased to assume exercise of potentially dilutive stock options, unvested restricted stock and contingently issuable shares using the treasury stock method and convertible preferred shares using the if-converted method, unless the effect of such increases would be anti-dilutive. The Company had 270.8 million and 204.0 million common stock equivalents for the three months ended March 31, 2016 and 2015, respectively, which were not included in the diluted net loss per common share as the common stock equivalents were anti-dilutive, as a result of being in a net loss position.

Commitments and Contingencies Disclosure [Text Block]	Note 14. Commitments and Contingencies Legal Proceedings The Company is subject to the possibility of loss contingencies arising in its business and such contingencies are accounted for in accordance with ASC Topic 450, "Contingencies.” In determining loss contingencies, the Company considers the possibility of a loss as well as the ability to reasonably estimate the amount of such loss or liability. An estimated loss is recorded when it is considered probable that a liability has been incurred and when the amount of loss can be reasonably estimated. In the ordinary course of business, the Company is routinely a defendant in or party to various pending and threatened legal claims and proceedings. The Company believes that any liability resulting from these various claims will not have a material adverse effect on its results of operations or financial condition; however, it is possible that extraordinary or unexpected legal fees could adversely impact the Company’s financial results during a particular period. During its ordinary course of business, the Company enters into obligations to defend, indemnify and/or hold harmless various customers, officers, directors, employees, and other third parties. These contractual obligations could give rise to additional litigation costs and involvement in court proceedings. On June 22, 2012, Geveran filed a lawsuit against the Company and several others in the Circuit Court of the Seventeenth Judicial Circuit in and for Broward County, Florida. On October 30, 2012, the court entered an order transferring the lawsuit to the Ninth Judicial Circuit in and for Orange County, Florida. The action, styled Geveran Investments Limited v. Lighting Science Group Corp., et al., Case No. 12-17738 (07), names the Company as a defendant, as well as Pegasus Capital and nine other entities affiliated with Pegasus Capital; Richard Weinberg, our former Director and former interim Chief Executive Officer and a former partner of Pegasus Capital; Gregory Kaiser, a former Chief Financial Officer; J.P. Morgan Securities, LLC (“J.P. Morgan”); and two employees of J.P. Morgan. Geveran seeks rescission of its $25.0 million investment in the Company, as well as recovery of interest, attorneys’ fees and court costs, jointly and severally against the Company, Pegasus Capital, Mr. Weinberg, Mr. Kaiser, J.P. Morgan and the two J.P. Morgan employees, for alleged violations of Florida securities laws. Geveran alternatively seeks unspecified money damages, as well as recovery of court costs, for alleged common law negligent misrepresentation against these same defendants. On August 28, 2014, the court issued an Order Granting Plaintiff’s Motion for Partial Summary Judgment under its First Cause of Action for Violation of the Florida Securities and Investor Protection Act. On November 25, 2015, the court entered judgment against the defendants, including the Company, on a joint and several basis, in the amount of approximately $40.2 million. On December 4, 2015, the Company, along with the other defendants, filed a Notice of Appeal to the Florida Fifth District Court of Appeal and posted a bond securing the judgment in the amount of approximately $20.1 million. Defendant J.P. Morgan also posted a separate bond in the amount of approximately $20.1 million, resulting in total bonding of approximately $40.2 million. On March 29, 2016, the trial court judge determined that the posted bonds were sufficient security to stay execution of the judgment pending the appeal. Although we cannot predict the ultimate outcome of this lawsuit, we believe the court’s summary judgment award in favor of Geveran was in error, that we will prevail on the appeal and the judgment will be overturned, and that the case will be remanded to the trial court for further proceedings. Were that to occur, we believe we have strong defenses against Geveran’s claims. However, in the event that we are not successful on appeal, we could be liable for the full amount of the $40.2 million judgment, plus post judgment interest. Such an outcome would have a material adverse effect on our financial position. The Company believes that, subject to the terms and conditions of the relevant policies (including retention and policy limits), directors’ and officers’ insurance coverage will be available to cover the substantial majority of its legal fees and costs in this matter. However, insurance coverage may not be available for, or such coverage may not be sufficient to fully pay, a judgment or settlement in favor of Geveran. Based upon the terms of an indemnification agreement, the Company has also paid, and may be required to pay in the in the future, reasonable legal expenses incurred by J.P. Morgan and its affiliates in this lawsuit in connection with the engagement of J.P. Morgan as placement agent for the private placement with Geveran. Such payments are not covered by the Company’s insurance coverage. The engagement letter executed with J.P. Morgan provides that the Company will indemnify J.P. Morgan and its affiliates from liabilities relating to J.P. Morgan’s activities as placement agent, unless such activities are finally judicially determined to have resulted from J.P. Morgan’s bad faith, gross negligence or willful misconduct. The Company is also a defendant in action brought by GE Lighting Solutions LLC (“GE Lighting”) in Federal District Court for the Northern District of Ohio in or about January 2013. GE Lighting asserts a claim of patent infringement against the Company under U.S Patent No. 6,787,999, entitled LED-Based M odular Lamp , and U.S . Patent No. 6,799,864, entitled High Power LED Power Pack for Spot Module Illumination . If GE Lighting were to prevail on its appeal, the case would likely be remanded to the trial court for further proceedings. Were that to occur, we believe that we have strong defenses against GE Lighting’s claims. However, if GE Lighting’s appeal is successful, there is no assurance that we will be successful in defending against this action. The outcome, if unfavorable, could have a material adverse effect on our financial position. Even if the outcome is favorable, this litigation could result in substantial additional costs to us, could be a distraction to management and could harm our financial position. In April 2015, LSG filed a lawsuit against several former employees and a company they formed seeking damages and injunctive relief arising out of the defendants’ misappropriation of our trade secrets and other intellectual property. Pursuant to the terms of a settlement agreement entered into in December 2015, certain of the individual defendants agreed not to use or disclose our intellectual property and to reimburse us for $200,000 in costs, and the defendants’ company agreed to pay us a commission equal to the greater of (i) $1.7 million and (ii) 5% of such company’s gross sales of biological and agricultural products during the three-year period ending January 2019 . In addition, the Company may be a party to a variety of legal actions, such as employment and employment discrimination-related suits, employee benefit claims, breach of contract actions, tort claims, shareholder suits, including securities fraud, intellectual property related litigation, and a variety of legal actions relating to its business operations. In some cases, substantial punitive damages may be sought. The Company currently has insurance coverage for certain of these potential liabilities. Other potential liabilities may not be covered by insurance, insurers may dispute coverage or the amount of insurance may not be sufficient to cover the damages awarded. In addition, certain types of damages, such as punitive damages, may not be covered by insurance and insurance coverage for all or certain forms of liability may become unavailable or prohibitively expensive in the future.

Significant Accounting Policies

Significant Accounting Policies (Policies)	3 Months Ended
	Mar. 31, 2016
Accounting Policies [Abstract]
Use of Estimates, Policy [Policy Text Block]	Use of Estimates The preparation of the accompanying consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions about future events. These estimates and the underlying assumptions affect the amounts of assets and liabilities reported, disclosures about contingent assets and liabilities, and reported amounts of revenue and expenses. Such estimates include the valuation of accounts receivable, inventories, intangible assets and other long-lived assets, legal contingencies, and customer incentives, among others. These estimates and assumptions are based on management’s best estimates and judgment. Management evaluates its estimates and assumptions on an on -going basis using historical experience and other factors, including the current economic environment, which management believes to be reasonable under the circumstances. The Company adjusts such estimates and assumptions when facts and circumstances dictate. Illiquid credit markets, volatile equity, foreign currency and energy markets and declines in consumer spending have combined to increase the uncertainty inherent in such estimates and assumptions. As future events and their effects cannot be determined with precision, actual results could differ significantly from these estimates. Changes in those estimates resulting from continuing changes in the economic environment will be reflected in the financial statements in future periods.
Cash and Cash Equivalents, Restricted Cash and Cash Equivalents, Policy [Policy Text Block]	Restricted Cash As of March 31, 2016 and December 31, 2015, as required by the Company’s five-year term loan (as amended from time to time, the “Medley Term Loan”) with Medley Capital Corporation (“Medley”), the Company was required to maintain a minimum restricted cash balance of $3.0 million to collateralize the Medley Term Loan. Changes in the restricted cash balance were reflected as a financing activity in the consolidated statements of cash flows.
Trade and Other Accounts Receivable, Policy [Policy Text Block]	Accounts Receivable The Company records accounts receivable at the invoiced amount when its products are shipped to customers or upon the completion of specific milestone billing requirements. The Company’s receivable balance is recorded net of allowances for amounts not expected to be collected from customers. This allowance for doubtful accounts is the Company’s best estimate of probable credit losses in the Company’s existing accounts receivable. Estimates used in determining the allowance for doubtful accounts are based on historical collection experience, aging of receivables and known collectability issues. The Company writes off accounts receivable when it becomes apparent, based upon age or customer circumstances that such amounts will not be collected. The Company reviews its allowance for doubtful accounts on a quarterly basis. Recovery of bad debt amounts previously written off is recorded as a reduction of bad debt expense in the period the payment is collected. Generally, the Company does not require collateral for its accounts receivable and does not regularly charge interest on past due amounts. As of March 31, 2016 and December 31, 2015, the Company’s allowance for doubtful accounts was $470,000 and $475,000, respectively. As of March 31, 2016 and December 31, 2015, $6.9 million and $4.2 million, respectively, of eligible accounts receivable were pledged as collateral for the three-year asset based revolving credit facility (as amended from time to time, the “FCC ABL”) entered into on April 25, 2014 with FCC, LLC d/b/a First Capital (“First Capital”). First Capital sold the FCC ABL to ACF FinCo I LP (“Ares”) in May 2015, and the FCC ABL is hereinafter referred to as the “Ares ABL”.
Revenue Recognition, Policy [Policy Text Block]	Revenue Recognition The Company records revenue when its products are shipped and title passes to customers. When sales of products are subject to certain customer acceptance terms, revenue from such sales is recognized once these terms have been met. The Company also provides its customers with limited rights of return for non-conforming shipments or product warranty claims.
Standard Product Warranty, Policy [Policy Text Block]	Product Warranties The Company generally provides a five-year limited warranty covering defective materials and workmanship of its products and such warranty may require the Company to repair, replace or reimburse the purchaser for the purchase price of the product. The estimated costs related to warranties are accrued at the time products are sold based on various factors, including the Company’s stated warranty policies and practices, the historical frequency of claims and the cost to repair or replace its products under warranty. The following table summarizes changes in the warranty provision for the three months ended March 31, 2016: Warranty provision as of December 31, 2015 $ 3,285,424 Additions to provision 233,757 Less warranty costs (309,140 ) Warranty provision as of March 31, 2016 $ 3,210,041
Fair Value of Financial Instruments, Policy [Policy Text Block]	Fair Value Measurements The Company utilizes valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible. The Company determines fair value based on assumptions that market participants would use in pricing an asset or liability in the principal or most advantageous market. When considering market participant assumptions in fair value measurements, the following fair value hierarchy distinguishes between observable and unobservable inputs, which are categorized in one of the following levels: • Level 1 Inputs: Unadjusted quoted prices in active markets for identical assets or liabilities accessible to the reporting entity at the measurement date. • Level 2 Inputs: Other than quoted prices included in Level 1 inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the asset or liability. • Level 3 Inputs: Unobservable inputs for the asset or liability used to measure fair value to the extent that observable inputs are not available, thereby allowing for situations in which there is little, if any, market activity for the asset or liability at measurement date. Fair Value of Financial Instruments Cash and cash equivalents, accounts receivable, accounts payable, amounts due under lines of credit and other short term borrowings, accrued expenses and note payable are carried at amounts that approximate their fair value due to the short-term maturity of these instruments and/or variable, market driven interest rates. The liabilities under derivative contracts, which represent warrants to purchase shares of the Company’s common stock, par value $0.001 per share (the “Common Stock”) were initially recorded at fair value and subsequently reflected at their fair value at the end of each reporting period. The fair value of the warrant issued to The Home Depot, Inc. (the “THD Warrant”) is determined using the Monte Carlo valuation method and will be adjusted at each reporting date until the underlying shares have been earned for each year . Such adjustments will be recorded as a reduction in the related revenue (sales incentive) from The Home Depot, Inc . (“The Home Depot”). Once a portion of the THD Warrant vests it is recorded at its fair value at the end of each subsequent reporting period.
New Accounting Pronouncements, Policy [Policy Text Block]	Recently Adopted Accounting Pronouncements In April 2015, the FASB issued ASU 2015-03 that intends to simplify the presentation of debt issuance costs. Debt issuance costs related to a recognized debt liability will be presented on the balance sheet as a direct deduction from the debt liability, similar to the presentation of debt discounts. ASU 2015-03 is effective for public business entities for fiscal years beginning after December 15, 2015, and interim periods within those fiscal years. Early adoption is permitted. The cost of issuing debt will no longer be recorded as a separate asset, except when incurred before receipt of the funding from the associated debt liability. The Company retrospectively adopted ASU 2015-03 as of January 1, 2016. The adoption of this guidance did not have a material impact on the condensed consolidated financial statements or notes to condensed consolidated financial statements. In November 2015, the FASB issued ASU No 2015-17 to simplify the presentation of deferred income taxes by requiring that deferred tax assets and liabilities be classified as non-current in the balance sheet. The new guidance is effective for the annual period ending after December 15, 2016, and interim periods thereafter, with early adoption permitted. The Company retrospectively adopted ASU 2015-17 as of January 1, 2016. The adoption of this guidance did not have a material impact on the condensed consolidated financial statements or notes to condensed consolidated financial statements. Recently Issued Accounting Pronouncements Not Yet Adopted In May 2014, the Financial Accounting Standards Board (the “FASB”) issued ASU 2014-09, which will replace most existing revenue recognition guidance in U.S. generally accepted accounting principles and is intended to improve and converge the financial reporting requirements for revenue from contracts with customers with International Financial Reporting Standards (“IFRS”). The core principle of ASU 2014-09 is that an entity should recognize revenue for the transfer of goods or services equal to the amount that it expects to be entitled to receive for those goods or services. ASU 2014-09 also requires additional disclosures about the nature, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments. ASU 2014-09 allows for both retrospective and prospective methods of adoption and is effective for periods beginning after December 15, 2016. In August 2015, the FASB issued ASU 2015-14 which provides a one-year deferral of the revenue recognition standard’s effective date. Public business entities are required to apply the revenue recognition standard to annual reporting periods beginning after December 15, 2017, and interim periods within those annual periods. Early application is permitted but not before the original effective date for public business entities (annual reporting periods beginning after December 15, 2016). The option to use either a retrospective or cumulative-effective transition method did not change. The Company is currently evaluating the method of adoption and the impact that the adoption of ASU 2014-09 will have on its consolidated financial statements. In August 2014, the FASB issued ASU 2014-15 requiring management to perform interim and annual assessments of an entity’s ability to continue as a going concern within one year of the date the financial statements are issued. The standard also provides guidance on determining when and how to disclose going-concern uncertainties in the financial statements. The new guidance is effective for the annual period ending after December 15, 2016, and interim periods thereafter, with early adoption permitted. The Company is currently evaluating the method of adoption and the impact that the adoption of ASU 2014-15 will have on its consolidated financial statements. In July 2015, the FASB issued ASU 2015-11, “Inventory (Topic 330).” This update requires an entity to measure inventory within the scope of the update at the lower of cost and net realizable value. This update is effective for financial statements issued for fiscal years beginning after December 15, 2016, and interim periods within those fiscal years. The Company is currently evaluating the method of adoption and the impact that the adoption of ASU 2015-11 will have on its consolidated financial statements. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842). ASU 2016-02 introduces a lessee model that brings most leases on the balance sheet. The new standard also aligns many of the underlying principles of the new lessor model with those in ASC 606, the FASB's new revenue recognition standard (e.g., those related to evaluating when profit can be recognized). Furthermore, ASU 2016-02 addresses other concerns related to the current leases model. For example, ASU 2016-02 eliminates the requirement in current U.S. GAAP for an entity to use bright-line tests in determining lease classification. The standard also requires lessors to increase the transparency of their exposure to changes in value of their residual assets and how they manage that exposure. The Company is required to adopt ASU 2016-02 for periods beginning after December 15, 2018, including interim periods, with early adoption permitted. The Company is currently evaluating the method of adoption and the impact that the adoption of ASU 2016-02 will have on its consolidated financial statements.
Reclassification, Policy [Policy Text Block]	Reclassification Certain prior period amounts in the accompanying consolidated financial statements have been reclassified to conform to the current year presentation. These reclassifications had no effect on previously reported net loss or stockholders’ deficit.
