Optimized for non-directional and small LED replacement lamps such as B10 candelabra, E17, GU10 and A19 bulbs, the XLamp XT-E High-Voltage White LED delivers both high lumen output and high efficacy in a small footprint. The XLamp XT-E High-Voltage LED is 15 to 40 times smaller than high-voltage LED arrays, making it easy to integrate into the smallest LED designs. Its small form factor provides more room for the LED driver and heat sink in space-constrained designs. The XLamp XT-E High-Voltage White LED enables driver circuits that are up to 10% lower cost, 15% smaller size, 10% cooler and 20% more efficient than standard-voltage LEDs. These system optimizations can enable more efficient, cost-effective and better LED replacement lamps for small bulb types.
