May 5, 2006—LED Lighting Fixtures, Inc. (LLF) announces that independent third party testing has confirmed that the company’s recessed luminaire has an efficacy of 73 lumens per watt, a gain in efficacy of 35 percent over test results of its predecessor just two months ago.
This advance paves the way for wider acceptance of light-emitting diode (LED) technology in the US lighting market, estimated at $12 billion, according to LLF.
In recent testing conducted at CSA International’s Lighting Laboratory in Atlanta, LLF’s fixtures continuously produced more than 700 lumens using less than 10 watts from a wall plug AC source. This result, explains LLF, was significantly higher than the company’s 54 lumens per watt achieved four months earlier. Color temperature was measured at 32Kelvin, with a color rendering index of 92. LLF’s proprietary white light technology allows for a wide range of desired color temperatures. The company used LEDs supplied by Cree, Inc.
“Our results were documented by a Nationally Recognized Testing Laboratory using stringent scientific standards,” says LLF Chief Technology Officer Gerry Negley. “The tests were conducted using a six-inch recessed fixture and the light source was measured with an integrating sphere after reaching thermal equilibrium. Because our fixtures use less than 10 watts they are completely cool to the touch.”
LLF also points out that the latest prototype fixture operates using 15 percent of the power of standard 65-watt incandescent bulbs.
LED Lighting Fixtures, Inc. (LLF) is a privately held company headquartered in the Research Triangle area of North Carolina. Its mission is to accelerate the adoption and evolution of light emitting diodes (LEDs) into high-volume general lighting applications so that consumers can realize lower energy and maintenance costs.
