Lighting Science Group's LED bulbs pas rigorous Energy Star testing standard

Oct. 25, 2010
Date Announced: 25 Oct 2010 Satellite Beach, Florida -– Continuing to outshine the competition—Lighting Science Group (OTCBB: LSCG) now has five ENERGY STAR labeled LED light bulbs. The ENERGY STAR approved DEFINITY PAR38 (narrow flood and spot), PAR30 (narrow flood) and MR16 (flood and narrow flood) LED bulbs are 80% more efficient than the 75, 60, and 25 watt incandescent halogen bulbs that they replace, are fully dimmable, and have approximately 50 percent more lumens (light output) than competing products. The DEFINITY bulbs are the first in a line of Lighting Science Group products going through the ENERGY STAR approval process that also include A19, PAR20, and G25 bulb types. Unlike CFLs, the DEFINITY LED bulbs contain no mercury, are completely recyclable, are instant on, and offer outstanding light quality.The Company’s PAR38 narrow flood was the industry’s first ENERGY STAR LED bulb to be approved back in September. ENERGY STAR is the trusted, government-backed symbol that makes it easy for consumers to identify and purchase energy-efficient products that offer savings on energy bills without sacrificing performance, features, and comfort. “Leading the industry in the number of ENERGY STAR approved LED bulbs is a true testament of the superior quality and performance of our LED products,” said Zach Gibler, Chief Executive Officer of Lighting Science Group. “While other companies are struggling to develop high performance LED lighting products, we are bringing to market state-of-the-art lighting solutions that Americans can afford.” To ensure both performance and reliability, the cULus-listed DEFINITY LED line was tested under the rigorous ENERGY STAR Eligibility Criteria, Version 1.1 process by an independent laboratory approved by the U.S. Department of Energy’s CALiPER program. To receive the ENERGY STAR label for an integral LED lamp, the DEFINITY PAR38, PAR30, and MR16 bulbs were tested under the LM79 standard for overall efficiency, color temperature, color rendering, color spatial uniformity, and light emission pattern. Additional testing required for ENERGY STAR approval included: rapid cycle thermal stress testing, in-situ temperature testing, both lumen maintenance and color maintenance testing, and an operational test for 3,000 hours at elevated ambient temperature.Lighting Science Group DEFINITY bulbs are offered through lighting distributors worldwide and directly by the company.
