Cree debuts 122lm neutral-white LEDs optimized for outdoor applications

LED chip, lamp and lighting fixture maker Cree Inc of Durham, NC, USA has announced the commercial availability of new, high-efficiency ‘outdoor white’ XLamp XP-E LEDs, which provide the same flux and efficacy levels as XLamp cool-white LEDs but with a neutral color that more closely matches existing high-intensity discharge (HID) installations (with a correlated color temperature, CCT, of 4000–5300K).

Available in sample quantities now and in production quantities with standard lead times, the outdoor white XLamp XP-E LEDs deliver up to 122 lumens output at a drive current of 350mA (at a CCT of 4500K).

“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,” says Paul Thieken, 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,” he adds.

Cree’s IES LM-80 lumen maintenance test data for the XLamp XP-E LED has been accepted by ENERGY STAR. The firm'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.
