Lighting-Class LEDs Up Performance Standards

Commercially available, single-die XLamp XM-L LEDs deliver up to 1,000 lumens at 100 lumens per Watt, making them the industry's brightest, highest performance lighting-class LEDs. Cool white (6500 K) XLamp XM-L LEDs deliver 1000 lumens with 100 lumens per Watt efficacy at 3A. In a 5 mm x 5 mm footprint, they deliver a light output and efficacy of 160 lumens per Watt at 350 mA and up to 315 lumens and 150 lumens per Watt at 700 mA. This represents a 20% efficiency gain over current XLamp XP-G LEDs. CREE INC., Durham, NC. (919) 313-5300.
