Cree’s XLamp XM LED delivers record-breaking efficacy of 160 lumens per watt at 350 mA

LED chip, lamp and lighting fixture maker Cree Inc of Durham, NC, USA has introduced a new lighting-class LED platform, the XLamp XM LED. According to the firm, the single chip LED has a record-breaking efficacy of 160 lumens per watt at 350mA. It also delivers 750 lumens at 2A, which is equivalent to the light output of a 60W incandescent light bulb at less than 7 watts.

“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,” said Chuck Swoboda, Cree chairman and CEO.

Cree says that a cool white XM LED driven at 350mA can produce 160 lumens at 160 lumens per watt. Furthermore. the new platform has a larger footprint than the firm’s XP family. At 2A, 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% improvement over Cree’s flagship XLamp XP-E LED.

Samples of the XLamp XM LEDs are available for order, with commercial availability targeted for Fall 2010.
