XT-E and XM-L High Voltage White LEDs

Most small LED replacement lamps on the market are too dim or inefficient and larger than the bulbs they are supposed to replace. With Cree XLamp high voltage LEDs, you can eliminate this trade-off. Optimized for small form factor lighting, Cree XLamp XT-E and XM-L high voltage white LEDs offer the right combination of efficacy and size to enable LED replacements for up to a 40 W B10 lamp.

Optimized for non-directional and small LED replacement lamps, Cree XLamp XT-E and XM-L high voltage White LEDs deliver both high lumen output and high efficacy in a small footprint. With a typical voltage of 46 V, the LEDs enable driver circuits that are up to 10% lower cost, 15% smaller size, 10% cooler and 20% more efficient than standard voltage LEDs.
