The LED also delivers 750 lumens at 2A, which is equivalent to the light output of a 60W incandescent light bulb at less than 7W, according to the company.
Cree claimed that its XM LED driven at 350mA can produce 160 lumens at 160 lumens per watt. The new platform has a larger footprint than Cree’s XP family and also offers a combination of high efficacy at high drive currents.
At 2A, an XM LED produces 750 lumens at 110 lumens per watt. The thermal resistance of the XM platform is 2 degrees centigrade per watt and a 350% improvement over Cree’s XLamp XP-E LED, the company added.
Samples of the XLamp XM LEDs are available for order with standard lead times and commercial availability is targeted for Fall 2010.
Chuck Swoboda, chairman and CEO of Cree, said: ”This new platform continues Cree’s well-established record of turning R&D innovations into products.
”We continue to set the pace for LED performance, establishing new benchmarks that make you wonder why anyone would consider last-century’s energy-wasting technology.”
