We develop, market and sell high quality light-emitting diode (“LED”) lighting and controls products and UVCD products in the commercial market and military maritime market (“MMM”), and expect to expand our offerings into the consumer market in the second half of 2021. Our mission is to enable our customers to run their facilities and offices with greater energy efficiency, productivity, and human health through advanced LED retrofit and UVCD solutions. Our goal is to be the LED and human-centric lighting (“HCL”) technology and market leader for the most demanding applications where performance, quality, value, environmental impact and health are considered paramount. We specialize in LED lighting retrofit by replacing fluorescent, high-intensity discharge lighting and other types of lamps in institutional buildings for primarily indoor lighting applications with our innovative, high-quality commercial and military tubular LED (“TLED”), as well as other LED and lighting control products for commercial and consumer applications. In late 2020, we announced the launch of our UVCD product portfolio, which is being brought to market throughout the second half of 2021.</span></div><div><span><br/></span></div><div><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:115%">On June 11, 2020, in accordance with previous stockholder approval, our board of directors effected a 1-for-5 (the “Split Ratio”) reverse stock split of the Company’s common stock, par value $0.0001 per share. The reverse stock split became effective immediately upon the filing of the Certificate of Amendment to the Company’s Certificate of Incorporation, as amended (the “Certificate of Incorporation”), with the Delaware Secretary of State (the “Effective Time”). At the Effective Time, every five shares of common stock issued and outstanding automatically combined into one validly issued, fully paid and non-assessable share of common stock. No fractional shares were issued as a result of the reverse stock split. The $0.0001 par value per share of common stock and other terms of the common stock were not affected by the reverse stock split. The number of authorized shares of common stock under the Certificate of Incorporation remained unchanged at 50,000,000 shares. Proportional adjustments were made to the conversion and exercise prices of our outstanding warrants and stock options, and to the number of shares issued and issuable under our stock incentive plans in connection with the reverse stock split. The information presented in the financial statements for all prior periods have been retroactively adjusted to reflect the reverse stock split. Preferred shares outstanding were not affected by the reverse stock split and, as such, those shares have not been adjusted.</span></div>

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 us in the future, actual results may vary 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 of property and equipment; valuation allowance for net deferred taxes; the cost and offsetting income related to sub-leased property; and stock-based compensation. In addition, estimates and assumptions associated with the determination of the fair value of financial instruments and evaluation of long-lived assets for impairment requires considerable judgment. Actual results could differ from those estimates and such differences could be material.</span></div>
