Item 3. Source and Amount of Funds or Other Consideration

The disclosure in Item 4 below is incorporated herein by reference.

Item 4. Purpose of Transaction

Subscription Agreement

On April 13, 2012, Lighting Science Group Corporation (the “Issuer”) entered into a Subscription Agreement (the “Subscription Agreement”) with LSGC Holdings II pursuant to which the Issuer issued 2,000 units (the “Series G Units”) of the Issuer’s securities to LSGC Holdings II at a price per Series G Unit of $1,000.00 (the “Series G Offering”) for total consideration of $2,000,000. Each Series G Unit consists of: (i) one share of the Issuer’s Series G Preferred Stock, par value $0.001 per share (the “Series G Preferred Stock”) and (ii) 83 shares of the Issuer’s common stock, par value $0.001 per share.

Pursuant to the Subscription Agreement, if, at any time while LSGC Holdings II holds any shares of Series G Preferred Stock purchased pursuant to the Subscription Agreement, the Issuer issues securities (other than pursuant to the Issuer’s equity-based compensation plans) that result in gross proceeds to the Issuer of at least $50,000,000 (a “Subsequent Issuance”), the Issuer must notify LSGC Holdings II of the terms and conditions of such Subsequent Issuance. Simultaneous with, and subject to the closing and terms and conditions of, such Subsequent Issuance, LSGC Holdings II would have the right to: (i) require the Issuer to use the proceeds of such Subsequent Issuance to redeem all of LSGC Holdings II Series G Preferred Stock or (ii) convert all or a portion of LSGC Holdings II Series G Preferred Stock into the securities issued in the Subsequent Issuance on substantially the same terms and conditions governing the Subsequent Issuance. If LSGC Holdings II elects to convert its shares of Series G Preferred Stock, LSGC Holdings II would retain all of the shares of common stock issued in conjunction with each converted share of Series G Preferred Stock.

In addition, if, at any time prior to November 17, 2013, the Issuer issues securities (other than issuances pursuant to the Issuer’s equity-based compensation plans or pursuant to a Subsequent Issuance) which PCA LSG Holdings, LLC, in its sole reasonable discretion, determines are more favorable than the Series G Units, LSGC Holdings II may exchange all of its Series G Units, valued at the Liquidation Value (as defined in the Certificate of Designation concerning the Series G Preferred Stock) of the Series G Preferred Stock included in such Series G Units, for such newly issued securities.

The foregoing description of the Subscription Agreement does not purport to be complete and is qualified in its entirety by reference to the full text of the Subscription Agreement, which is included as Exhibit 10.1 to this Amendment No. 24 and is incorporated by reference herein.

The Reporting Persons continuously assess the Issuer’s business, financial condition, results of operations and prospects, general economic conditions, other developments and additional investment opportunities. Depending on such assessments, the Reporting Persons may acquire additional shares of Common Stock or may determine to purchase, sell or otherwise dispose of all or some of the Issuer’s securities in the open market, as applicable, in privately negotiated transactions or otherwise. Such actions will depend upon a variety of factors, including, without limitation, current and anticipated future trading prices, the financial condition, results of operations and prospects of the Issuer, alternative investment opportunities, general economic, financial market and industry conditions and other factors that the Reporting Persons may deem material to its investment decision.

Except as set forth herein or in previous amendments to this Schedule 13D, as the case may be, the Reporting Persons do not have present plans or proposals at this time that relate to or would result in any of the transactions described in subparagraphs (a) through (j) of Item 4 of Schedule 13D.

Item 5. Interest in Securities of the Issuer

Items 7 through 11 and 13 of each of the cover pages of this Amendment No. 24 are incorporated herein by reference. Such information is based upon 207,168,141 shares of common stock outstanding as of April 13, 2012.

The disclosure regarding the Subscription Agreement and the related disclosure in Item 4 is incorporated herein by reference.

Except as set forth herein and in our previously filed amendments to Schedule 13D, as the case may be, there have been no other transactions in the class of securities reported on that were effected within the past sixty days.

Item 6. Contracts, Arrangements, Understandings or Relationships with Respect to Securities of the Issuer

The disclosure regarding the Subscription Agreement and related disclosure in Item 4 is incorporated herein by reference.

The Subscription Agreement is incorporated by reference as Exhibit 10.1 to this Amendment No. 24 and is incorporated herein by reference.

Item 7. Material to be Filed as Exhibits

10.1	Series G Unit Subscription Agreement, dated as of April 13, 2012, by and between Lighting Science Group Corporation and LSGC Holdings II, LLC (incorporated by reference to Exhibit 10.1 to the Issuer’s Current Report on Form 8-K, filed with the SEC on April 19, 2012).
