Cree has announced their new ‘revolutionary’ Xlamp XM LED that delivers a lighting-class efficiency record of 160 lumens per watt when driver at 350mA (1w per LED). Just as impressive, the Cree XM LED rips out 750 lumens from a single chip when driven at 2A, for just under 7 watts of total electric consumption. Even when driven this hard the XM LED still boast a luminous efficacy of 110 lumens per watt, trumping most metal halides. Let’s hope these get the 450nm royal blue treatment.
The Cree XM series LED will emit roughly twice the amount of light as the robust XR-E (shown above)
The new XM package is larger than the XP package and features thermal resistance of 2 degrees celsius per watt, which is a 350% improvement over the XP-E. Cree states that ‘samples are available for order with standard lead times’. The masses will have to wait till the fall to get their hands on them. See the full press release from Cree below:
Cree Announces Revolutionary New LED Platform Delivering 160 Lumens per Watt
XLamp® XM LEDs Are Most Efficient Lighting-Class LEDs in the Industry
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 Cree’s 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-century’s 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 Cree’s 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 Cree’s 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.
