Sounds pretty cool, maybe something that would be good to replace the P7's and MC-E's with better efficiency.
Here's the article...CREE |Cree Announces Revolutionary New LED Platform Delivering 160 Lumens per Watt
DURHAM, N.C., April 12, 2010 Cree, Inc. (Nasdaq: CREE), a market leader in LED lighting, announces a breakthrough new lighting-class LED platform, the XLamp® XM LED. This new single chip LED delivers record-breaking efficacy of 160 lumens per watt at 350 mA. The LED also delivers 750 lumens at 2 A, which is equivalent to the light output of a 60 W incandescent light bulb at less than 7 watts.
This new platform continues Crees well-established record of turning R&D innovations into products, said Chuck Swoboda, Cree chairman and CEO. We continue to set the pace for LED performance, establishing new benchmarks that make you wonder why anyone would consider last-centurys energy-wasting technology.
A cool white XM LED driven at 350 mA can produce 160 lumens at 160 lumens per watt. The new platform has a larger footprint than Crees XP family and also offers the unique combination of very high efficacy at very high drive currents. At 2 A, an XM LED produces 750 lumens at 110 lumens per watt. The thermal resistance of the XM platform is 2 degrees C per watt an industry-leading technology breakthrough and a 350 percent improvement over Crees flagship XLamp XP-E LED.
Samples of the XLamp XM LEDs are available for order with standard lead times and commercial availability is targeted for Fall 2010.
Sounds pretty cool, maybe something that would be good to replace the P7's and MC-E's with better efficiency.
