Accounting Policies, by Policy (Policies)

3 Months Ended

Mar. 31, 2013

Basis of Accounting, Policy [Policy Text Block]

Basis of Presentation

The financial statements include the accounts of the Company and its subsidiaries, Stones River Companies, LLC (“SRC”) in Nashville, Tennessee, and Crescent Lighting Limited (“CLL”) located in the United Kingdom.  All significant inter-company balances and transactions have been eliminated.

We have prepared the accompanying financial data for the three months ended March 31, 2013 and 2012 pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”).  Certain information and footnote disclosures normally included in financial statements prepared in accordance with generally accepted accounting principles (“GAAP”) in the U.S. have been condensed or omitted pursuant to such rules and regulations.  The accompanying financial data and information should be read in conjunction with our 2012 Annual Report on Form 10-K.

In the opinion of management, the accompanying condensed consolidated financial statements contain all normal and recurring adjustments necessary to present fairly our Condensed Consolidated Balance Sheets as of March 31, 2013 and December 31, 2012, Condensed Consolidated Statements of Comprehensive Income for the three months ended March 31, 2013 and 2012, Condensed Consolidated Statements of Operations for the three months ended March 31, 2013 and 2012, and Condensed Consolidated Statements of Cash Flows for the three months ended March 31, 2013 and 2012.

The preparation of condensed consolidated financial statements in accordance with GAAP in the U.S. requires management to make estimates and assumptions that affect the amounts reported in our condensed consolidated financial statements and accompanying notes.  Management bases its estimates on historical experience and various other assumptions believed to be reasonable.  Although these estimates are based on management’s best knowledge of current events and actions that may impact the company in the future, actual results may be different from the estimates.  Estimates include, but are not limited to, the establishment of reserves for accounts receivable, sales returns, inventory obsolescence and warranty claims; the useful lives for property, equipment, and intangible assets; revenues recognized on a percentage-of-completion basis; and stock-based compensation.  In addition, estimates and assumptions associated with the evaluation of long-lived assets for impairment requires considerable judgment.  Actual results could differ from those estimates and such differences could be material.

The Company’s independent public accounting firm has issued an opinion in connection with the Company’s 2012 Annual Report on Form 10-K raising substantial doubt about the Company’s ability to continue as a going concern.  The interim financial statements have been prepared assuming the Company will continue to operate as a going concern, which contemplates the realization of assets and the settlement of liabilities in the normal course of business.  The interim financial statements do not include any adjustments to reflect the possible future effects on the recoverability and classification of assets or the amounts and classification of liabilities that may result from uncertainty related to our ability to continue as a going concern.

Reclassification, Policy [Policy Text Block]

Reclassifications

Certain prior year amounts have been reclassified within the Condensed Consolidated Financial Statements (“financial statements”), and related notes thereto, to be consistent with the current year presentation.

New Accounting Pronouncements, Policy [Policy Text Block]

Recent Accounting Pronouncements

In February 2013, the FASB issued ASU 2013-02,Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income under Topic 220, which requires an entity to provide information about the amounts reclassified out of accumulated other comprehensive income by component (the respective line items of net income).  This pronouncement is effective for fiscal years, and interim periods within those years, beginning after December 15, 2012.  We adopted this ASU and the impact was not material to our disclosures for the quarter ended March 31, 2013.

Update to Significant Accounting Policies

There have been no material changes to our significant accounting policies, as compared to the significant accounting policies described in our Annual Report on Form 10-K for the fiscal year ended December 31, 2012.

Earnings Per Share, Policy [Policy Text Block]

Earnings (Loss) per Share

Basic loss per share is computed by dividing the net loss available to common shareholders by the weighted average number of common shares outstanding for the period.  Diluted loss per share is computed giving effect to all dilutive potential common shares that were outstanding during the period.  Dilutive potential common shares consist of incremental shares upon exercise of stock options and warrants, unless the effect would be anti-dilutive.

A reconciliation of basic and diluted loss per share is provided as follows (in thousands, except per share amounts):

	Three months ended March 31,
	2013			2012
Basic and diluted loss per share:
Net loss	$	(1,428	)	$	(1,867	)
Basic and diluted loss per share:
Weighted average shares outstanding		44,699			31,621
Basic and diluted net loss per share	$	(0.03	)	$	(0.06	)

Options and warrants to purchase approximately 14,177,550 and 15,304,000 shares of common stock, were outstanding at March 31, 2013 and 2012, respectively, but were not included in the calculation of diluted net loss per share because their inclusion would have been anti-dilutive.

Share-based Compensation, Option and Incentive Plans Policy [Policy Text Block]

Stock-Based Compensation

The Company’s stock-based compensation plan is described in detail in its 2012 Annual Report on Form 10-K.  The following table summarizes the Company’s stock-based compensation (in thousands):

	Three months ended March 31,
	2013		2012
Research and development	$	7	$	6
Sales and marketing		8		8
General and administrative		30		44
Total stock-based compensation	$	45	$	58

Total unearned compensation of $315 thousand related to stock options remains at March 31, 2013 compared to $317 thousand at March 31, 2012.  These costs will be charged to expense and amortized on a straight line basis in future periods through the third quarter of 2016.  The weighted average period over which this unearned compensation is expected to be recognized is approximately 2.2 years.

The fair value of each stock option is estimated on the date of grant using the Black-Scholes option pricing model.  Estimates utilized in the calculation include the expected life of the option, risk-free interest rate, and expected volatility, and are further comparatively detailed as follows:

	Three months ended March 31,
	2013			2012
Fair value of options issued	$	0.15		$	0.21
Exercise price	$	0.23		$	0.39
Expected life of option (years)	8.3			6.1
Risk-free interest rate		1.57	%		1.48	%
Expected volatility		83.82	%		58.05	%
Dividend yield		0	%		0	%

Option activity under the Company’s stock plans during the three months ended March 31, 2013 was as follows:

	Options			Weighted Average Exercise Price		Weighted Average Remaining Contractural Term (in Years)

Exercisable as of March 31, 2013		1,565,450		$	2.74		5.9

Standard Product Warranty, Policy [Policy Text Block]

Product Warranties

The Company warrants finished goods against defects in material and workmanship under normal use and service for periods generally between one and five years for products and labor.  Settlement costs consist of actual amounts expensed for warranty services which are largely a result of third-party service calls and the costs of replacement products.  A liability for the estimated future costs under product warranties is maintained for products outstanding under warranty and is included in “Accrued liabilities” in the Condensed Consolidated Balance Sheets.  The warranty activity for the respective periods is as follows (in thousands):

	Three months ended March 31,
	2013			2012
Balance at the beginning of the period	$	159		$	100
Accruals for warranties issued		16			31
Settlements made during the period (in cash or in kind)		(35	)		(21	)
Balance at the end of the period	$	140		$	110
