Cree demonstrated its worldwide strength in Silicon Carbide technology. The company also leads the LED lighting revolution and is setting the stage to obsolete the incandescent light bulb through the use of energy-efficient, environmentally friendly LED lighting. Product families include LED fixtures and bulbs, blue and green LED chips, high-brightness LEDs, lighting-class power LEDs, power-switching devices and radio-frequency/wireless devices. Cree's vertical integration is unique amongst competitors and provides a broad, deep patent portfolio with 90 patents issued for power alone. Advantages are:

Commercially Available Single-die XLamp® XM-L LEDs Deliver 1000 Lumens, at 100 Lumens per Watt Cree, Inc. launched 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 3A. 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.
