Cree launches single-die lighting-class LEDs delivering 1000lm at efficacy of 100lm/W

LED chip, lamp and lighting fixture maker Cree Inc of Durham, NC, USA has announced the commercial availability of what it claims is the industry’s brightest, highest-performance lighting-class LEDs. Designed for very-high-lumen applications such as high-bay or roadway lighting, the XLamp XM-L LED has gone from concept to commercial availability in less than eight months.

Cool-white (6500K) XLamp XM-L LEDs deliver 1000 lumens with 100 lumens per watt efficacy at 3A. In a compact 5mm x 5mm footprint, XM-L LEDs offer the combination of very high efficacy at very high drive currents, delivering light output and efficacy of 160 lumens per watt at 350mA and up to 315 lumens and 150 lumens per watt at 700mA, providing a 20% efficiency gain from Cree's existing XLamp XP-G LEDs.

“An LED with this level of light output and this level of efficacy can accelerate the development of high-output commercial lighting products and could enable applications we haven't even thought of yet,” reckons John Edmond, director of advanced optoelectronics.

XLamp XM-L LEDs are available in sample and production quantities with standard lead times.
