Description. The Cree XLamp® XP-E2 White LED is Cree's newest version of the older XLamp XP-E. Unlike the original XP-E, the XP-E2 is built from the SC3 technology platfrom and can boast higher lumens per watt and lumens per dollar.
*Missing data has been estimated by measuring voltage and current values using an adjustable power supply and looking up the values on the Cree XP-E2 R3 data sheet. On mine the rubber band that covers the USB charging port was hard to turn but a tiny dab of silicone grease spread around the band's track fixed that.
