Cree LED luminaire reaches 100lm/W for indoor lighting

LED chip, lamp and lighting fixture maker Cree Inc of Durham, NC, USA has announced a new LED-based troffer that delivers more than 100 lumens per Watt fixture efficacy, which is claimed to be the first indoor fixture known to deliver this level of performance.

Shown at Lightfair 2010 in Las Vegas, the LR24HE is 30% more efficient than the best 2-foot-by-2-foot fluorescent troffers and 15% more efficient than the best 2-foot-by-4-foot fluorescent troffers, claims Cree. Designed to last at least 50,000 hours, the LR24HE uses the firm’s TrueWhite technology to deliver 3200 lumens at 3500K with a 90 CRI (color rendering index).

“By using the LR24HE, which is the most efficient product for general illumination, lighting designers and architects now have the freedom to reintroduce accent and decorative lighting and still meet energy codes or achieve LEED points,” says Gary Trott, VP market development, LED Lighting.

The LR24HE is planned for commercial availability in late summer, and will offer Cree's new five-year warranty.

Cree also says that it will reduce the price of its LR24 LED troffer by 15% to reduce upfront cost, as it aims to accelerate the adoption of LED lighting.
