CHARLOTTE, NC — June 22, 2009 — Nexxus Lighting, Inc. (NASDAQ: NEXS) today announced that it has closed a private placement of promissory notes and warrants to accredited investors, for aggregate consideration of approximately $4 million in cash. The net proceeds will be used for working capital and general corporate purposes, to support the growth of the Company’s Array™ Lighting product line and to fund additional investments in the expansion of the Array™ family and associated intellectual property.

“As sales and production of our new Array product offering increase we are pleased to attract the resources required to support our growth strategy,” stated Mike Bauer, President and CEO of Nexxus Lighting. “As an example of the continuing adoption and expansion of the Array™ line, we are pleased to announce that we completed the design, initial production and shipment of the new 230 volt, 50 mhz Par 30 lamp. This lamp includes a new patent-pending circuitry design. Called CSD or Continuous Step Drive™, this circuitry is a unique and more efficient way to operate and dim clusters of LEDs. We already shipped an initial order of this product for a large European retailer who will be installing the lamps in multiple locations. We look forward to expanding sales of the 230 volt product in the 3^rd quarter.”

The Notes mature on January 5, 2011, bear interest at the rate of 10% per annum and are secured by a security interest in all of the Company’s assets. The Notes may be redeemed by the Company at any time without premium or penalty. For each $1.00 in principal amount of Note, the holder received warrants to purchase .075 shares of the Company’s common stock at an exercise price of $6.43 per share expiring three years from the date of issuance. An aggregate of 285,000 warrants were issued to the noteholders at closing. Depending upon when the Notes are repaid, warrants to purchase up to .075 additional shares of the Company’s common stock per $1.00 of principal amount of the Notes will be issued.

“We believe this financing fits our needs and enables us to support our planned operations and growth”, stated Gary Langford, Nexxus’ Chief Financial Officer. “Maintaining the proper capital structure is crucial to ensuring liquidity and maximizing shareholder value. With Array so new and our pipeline building this financing allows us to focus on the execution of our growth plans and our working capital requirements.”
