Revenue recognition - Generally, the Company recognizes revenue for its products upon shipment to customers, provided no significant obligations remain and collection is probable. For sales that include customer acceptance terms, revenue is recorded after customer acceptance. It is the Company's policy that all sales are final. Requests for returns are reviewed on a case by case basis. As revenue is recorded, the Company accrues an estimated amount for product returns as a reduction of revenue. As the Company's products are new in the consumer market channel, the Company increased its reserve estimate related to product returns for this channel. The level of returns may fluctuate from the Company's estimate. The Company offers early payment discounts to select customers. Revenue is recorded net of the amount of the early payment discounts that the Company estimates will be claimed by customers. Our products typically carry a warranty that ranges from two to five years and includes replacement of defective parts. A warranty reserve is recorded for estimated costs associated with potential warranty expenses on previous sales.

Financial instruments –FASB Accounting Standards Codification ("ASC") 820 "Fair Value Measurements and Disclosures" ("ASC 820") defines fair value as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. ASC 820 also establishes a fair value hierarchy which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The standard describes three levels of inputs that may be used to measure fair value:

Level 1 - Quoted prices in active markets for identical assets or liabilities.

Level 2 - Inputs other than quoted prices included within Level 1 that are either directly or indirectly observable.

Level 3 - Unobservable inputs that are supported by little or no market activity, therefore requiring an entity to develop its own assumptions about the assumptions that market participants would use in pricing.

Fair value estimates discussed herein are based upon certain market assumptions and pertinent information available to management as of June 30, 2011. The Company uses the market approach to measure fair value for its Level 1 financial assets and liabilities, which includes cash equivalents of approximately $3,359,000 at June 30, 2011 and $5,024,000 at December 31, 2010, respectively. The market approach uses prices and other relevant information generated by market transactions involving identical or comparable assets or liabilities. The respective carrying value of certain on-balance-sheet financial instruments approximated their fair values. These financial instruments include cash, trade receivables, related party payables, accounts payable and accrued liabilities. Fair values were assumed to approximate carrying values for these financial instruments since they are short term in nature and their carrying amounts approximate fair values or they are receivable or payable on demand.

Derivative financial instruments – The Company does not use derivative instruments to hedge exposures to cash flow, market or foreign currency risk. Terms of convertible promissory note instruments are reviewed to determine whether or not they contain embedded derivative instruments that are required under FASB ASC 815 "Derivatives and Hedging" ("ASC 815") to be accounted for separately from the host contract, and recorded on the balance sheet at fair value. The fair value of derivative liabilities, if any, is required to be revalued at each reporting date, with corresponding changes in fair value recorded in current period operating results.

Freestanding warrants issued by the Company in connection with the issuance or sale of debt and equity instruments are considered to be derivative instruments, and are evaluated and accounted for in accordance with the provisions of ASC 815. Pursuant to ASC 815, an evaluation of specifically identified conditions is made to determine whether the fair value of warrants issued is required to be classified as equity or as a derivative liability.

Beneficial conversion and warrant valuation - In accordance with FASB ASC 470-20, "Debt with Conversion and Other Options" the Company records a beneficial conversion feature ("BCF") related to the issuance of convertible debt or preferred stock instruments that have conversion features at fixed rates that are in-the-money when issued, and the fair value of warrants issued in connection with those instruments. The BCF for the convertible instruments is recognized and measured by allocating a portion of the proceeds to warrants, based on their relative fair value, and as a reduction to the carrying amount of the convertible instrument equal to the intrinsic value of the conversion feature. The discount recorded in connection with the BCF and warrant valuation is recognized as non-cash implied preferred dividends from the date of issuance to the earliest conversion date, using the effective yield method.

Cash equivalents – Temporary cash investments with an original maturity of three months or less are considered to be cash equivalents.

Accounts receivable – Accounts receivable are customer obligations due under normal trade terms. The Company performs continuing credit evaluations of its customers' financial condition. The Company records an allowance for doubtful accounts based on specifically identified amounts that it believes to be uncollectible. Recovery of bad debt amounts previously written off is recorded as a reduction of bad debt expense in the period the payment is collected. If the Company's actual collection experience changes, revisions to its allowance may be required. After all attempts to collect a receivable have failed, the receivable is written off against the allowance.

Inventories – Inventories, excluding inventories at Lumificient Corporation, are stated at the lower of cost (average cost) or market. Inventories at Lumificient Corporation are stated at the lower of cost (first-in, first-out) or market. A reserve is recorded for any inventory deemed excessive or obsolete.

Property and equipment – Property and equipment are stated at cost. Depreciation is computed by the straight-line method and is charged to operations over the estimated useful lives of the assets. Maintenance and repairs are charged to expense as incurred. The carrying amount and accumulated depreciation of assets sold or retired are removed from the accounts in the year of disposal and any resulting gain or loss is included in results of operations. The estimated useful lives of property and equipment are as follows:

Intangible assets and goodwill – The Company accounts for its intangible assets and goodwill under FASB ASC 350 "Intangibles – Goodwill and Other" and FASB ASC 360 "Property, Plant, and Equipment".

Deferred rent – The Company accounts for certain operating leases containing predetermined fixed increases of the base rental rate during the lease term as rental expense on a straight-line basis over the lease term. The Company has recorded the difference between the amounts charged to operations and amounts payable under the leases as deferred rent in the accompanying consolidated balance sheets.

Long lived assets – The Company periodically evaluates the recoverability of its long-lived assets in accordance with FASB ASC 360, "Property, Plant, and Equipment", based on expected undiscounted cash flows and will recognize impairment of the carrying value of long-lived assets, if any is indicated, based on the fair value of such assets.

Shipping and handling costs – Shipping and handling costs related to the acquisition of goods from vendors are included in cost of sales.

Research and development – Research and development costs to develop new products are charged to expense as incurred.

Income taxes – Income taxes are provided for the tax effects of transactions reported in the financial statements and consist of taxes currently due plus deferred taxes resulting from temporary differences. Such temporary differences result from differences in the carrying value of assets and liabilities for tax and financial reporting purposes. The deferred tax assets and liabilities represent the future tax consequences of those differences, which will either be taxable or deductible when the assets and liabilities are recovered or settled. Valuation allowances are established when necessary to reduce deferred tax assets to the amount expected to be realized.

The Company accounts for uncertain tax positions under the provisions of FASB ASC 740-10 "Uncertainty in Income Taxes" ("ASC 740-10"). The Company has not recognized a liability as a result of the implementation of ASC 740-10. A reconciliation of the beginning and ending amount of unrecognized tax benefits has not been provided since there is no unrecognized benefit since the date of adoption. The Company has not recognized interest expense or penalties as a result of the implementation of ASC 740-10. If there were an unrecognized tax benefit, the Company would recognize interest accrued related to unrecognized tax benefits in interest expense and penalties in operating expenses.

Use of estimates – The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Loss per share – Basic loss per share is computed by dividing net loss by the weighted average common shares outstanding for the period. Diluted loss per share is computed giving effect to all potentially dilutive common shares. Potentially dilutive common shares may consist of incremental shares issuable upon the exercise of stock options and warrants and the conversion of outstanding convertible securities. In periods in which a net loss has been incurred, all potentially dilutive common shares are considered anti-dilutive and thus are excluded from the calculation. At June 30, 2011 and 2010, the Company had 7,469,825 and 7,795,863, respectively, common shares which may be acquired pursuant to outstanding employee stock options, warrants and convertible securities that were not included in the computation of loss per share at June 30, 2011 and 2010 because to do so would have been anti-dilutive.

Stock-based compensation – The Company accounts for stock-based compensation under the provisions of FASB ASC 718 "Compensation – Stock Compensation" ("ASC 718"), which requires the recognition of the cost of employee or director services received in exchange for an award of equity instruments in the financial statements and is measured based on the grant date fair value of the award. ASC 718 also requires the stock option compensation expense to be recognized over the period during which an employee is required to provide service in exchange for the award (typically, the vesting period).

The Company estimates the fair value of each option award issued under its stock option plans on the date of grant using a Black-Scholes option-pricing model that uses the assumptions noted below in accordance with ASC 718. The Company estimates the volatility of its common stock at the date of grant based on the historical volatility of its common stock. These historical periods may exclude portions of time when unusual transactions occurred. The Company determines the expected life based on historical experience with similar awards, giving consideration to the contractual terms, vesting schedules and post-vesting forfeitures. For shares that vest contingent upon achievement of certain performance criteria, an estimate of the probability of achievement is applied in the estimate of fair value. If the goals are not met, no compensation cost is recognized and any previously recognized compensation cost is reversed. The Company bases the risk-free interest rate on the implied yield currently available on U.S. Treasury issues with an equivalent remaining term approximately equal to the expected life of the award. The Company has never paid any cash dividends on its common stock and does not anticipate paying any cash dividends in the foreseeable future. In addition, the Company separates the grants into homogeneous groups and analyzes the assumptions for each group. The Company then computes the expense for each group utilizing these assumptions.

Under ASC 718, stock-based compensation expenses recognized in the accompanying unaudited statements of operations for the three months ended June 30, 2011 and 2010 was $129,826 and $75,014, respectively, which caused net loss to increase by that amount and basic and diluted loss per share for the three months ended June 30, 2011 and 2010 to increase by $0.01 and $0.00, respectively. Stock-based compensation expenses recognized in the accompanying unaudited statements of operations for the six months ended June 30, 2011 and 2010 was $202,815 and $177,755, respectively, which caused net loss to increase by that amount and basic and diluted loss per share for the six months ended June 30, 2011 and 2010 to increase by $0.01 and $0.01, respectively

Business segments – Pursuant to FASB ASC 280 "Segment Reporting", the Company is required to report segment information. In October of 2010, the Company sold substantially all of the assets of its legacy commercial/architectural lighting and pool and spa lighting businesses (the "Legacy Commercial and Pool Lighting Businesses"). As a result of the sale of the Company's Legacy Commercial and Pool Lighting Businesses, the Company reorganized its reporting structure into two reportable segments: LED replacement lamps and LED signage and lighting strips.

Recent accounting pronouncements – In June 2011, the FASB issued guidance on the presentation of comprehensive income, which amended existing guidance by allowing only two options for presenting the components of net income and other comprehensive income: (1) in a single continuous financial statement, statement of comprehensive income or (2) in two separate but consecutive financial statements, consisting of an income statement followed by a separate statement of other comprehensive income. Also, items that are reclassified from other comprehensive income to net income must be presented on the face of the financial statements. The guidance requires retrospective application, and it is effective for fiscal years, and interim periods within those years, beginning after December 15, 2011, with early adoption permitted. The adoption of this guidance is not expected to have a material impact on the Company's financial statements.
