Cree’s New Lighting-Class LEDs Shatter Industry Performance Standards

Commercially Available Single-Die XLamp® XM-L LEDs Deliver 1000 Lumens at 100 Lumens per Watt
DURHAM, N.C. -- Cree, Inc. (Nasdaq: CREE), a market leader in LED lighting, announces the commercial availability of the industry’s brightest, highest-performance lighting-class LEDs. With breakthrough light output and efficacy, Cree XLamp® XM-L LEDs are 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, demonstrating Cree’s proven commitment to developing the highest-performance, most cost-effective LEDs optimized for each lighting application.

“The XLamp XM-L LED can fundamentally change the way Cree customers look at LED light,” said John Edmond, Cree director of advanced optoelectronics. “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. This sets a new standard for LED performance.”

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

XLamp XM-L LEDs are available in sample and production quantities with standard lead times. To locate a distributor, please visit www.cree.com/buyxlamp.
