It puts out the same kind of light as an HID lamp but it's an LED. Available in sample quantities now, and in production quantities with standard lead times, the outdoor white XLamp XP-E LEDs from Cree deliver up to 122 lumens at 350 mA, at 4500 K.
"Outdoor lighting manufacturers can now offer either a cool white or a neutral white color point without trade-offs in lumen output or LED efficacy," said Paul Thieken, Cree director of marketing, LED components. "And since it's part of the XLamp XP-E family, changing existing XP-E system designs to high-efficiency outdoor white can be simple."
Cree's IES LM-80 lumen maintenance test data for the XLamp XP-E LED has been accepted by Energy Star. Cree's lighting-class XLamp XP LEDs are also UL-recognized, conforming to ANSI/UL 8750, Safety Standard for Light Emitting Diode (LED) Equipment for Use in Lighting Products.
