LEDs deliver up to 20% more lumens per watt

The XLamp XP-E2 LED by Cree delivers higher lumens per watt and lumens-per-dollar over the original XP-E LED. The XP-E2 LEDs increase the lumen output of XP-# designs for the same cost and power or lower system cost with fewer LEDs for improved lighting systems with little redesign. The same XP footprint (3.45mm x3.45mm) is used, ensuring compatibility with existing XP LED designs and the new brighter XLamp features 128 lumens power watt.
