Cree’s new lighting-class LED platform, the XLamp XM, delivers 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.
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 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°C/W – a 350% improvement over Cree’s flagship XLamp XP-E LED.
