29 Nov 2007 LED Lighting Fixtures Inc has built a prototype LED-based PAR 38 lamp that produces 659 lm from 5.8 watts of wall-plug power, with CCT of 2760 K and CRI of 91.2. At the White LEDs-07 conference in Japan last week, Tony van de Ven of LED Lighting Fixtures, Inc. (LLF) announced a new performance milestone for a prototype LED luminaire, which smashes existing records. LLF built a prototype PAR 38 self-ballasted lamp, which was tested under steady-state conditions by the National Institute of Standards and Technology (NIST) in Washington, DC. The LRP-38 lamp set a new standard for energy efficient lighting by producing 659 lumens at a mere 5.8 watts of wall-plug power, resulting in 113.6 delivered lumens per watt. The lamp emitted a warm incandescent-like color of 2760 Kelvin with a superb color rendering index of 91.2. The LLF lamp would use less than 9% and 30% of the energy consumed by incandescent and fluorescent sources, respectively. Gerry Negley, LLFs Chief Technology Officer said, The results of this prototype clearly demonstrate that LLFs LED technology will surpass all existing forms of lighting in terms of performance." At the conference, van de Ven, LLFs Hong Kong Managing Director, described the company's proprietary method to obtain simultaneously very high efficacy and color rendering. The PAR 38 fixture uses blue-shifted yellow Cree Xlamp LEDs in combination with red Golden Dragon LEDs from Osram Opto Semiconductors. Van de Ven said, We are very encouraged by our LRP-38 technology demonstration, as it is clearly the most energy efficient, high CRI white lighting solution ever developed. While there is currently no timetable for a production release, this result shows that LLFs technology with LED light sources has the ability to surpass 100 lumens per watt from a fixture, which is a revolutionary milestone for significant world-wide energy savings.
