Cree demos LR6 LED downlight with 102lm/W efficacy

At LIGHTFAIR International in New York, LED chip, lamp and lighting fixture maker Cree Inc of Durham, NC, USA demonstrated a prototype version of its LR6 LED recessed downlight that consumes just 6.5W of electricity, resulting in luminous output of 665 lumens, a fixture luminous efficacy of 102 lumens per watt, and a power factor of greater than 0.9.

The high-efficiency LR6 prototype features TrueWhite technology, resulting in a color rendering index (CRI) of 92 and a color temperature of 3500K.

“By using the latest Cree LEDs - the XLamp XP-G [also demonstrated at LIGHTFAIR International] - we were able to achieve this great efficiency,” says Gerry Negley, chief technologist for Cree LED Lighting.
