XLamp XT-E High-Voltage White

High efficacy and lower system cost for the smallest LED systems

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. With a typical voltage of 46 V, 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.

Cree Product Characterization Tool (PCT)

For help identifying the best Cree Xlamp® LEDs for your lighting-system design

The Cree Product Characterization Tool (PCT) allows you to select from multiple lighting-system design parameters to compare up to three LED models simultaneously.

Try the Product Characterization Tool (PCT)

For all valid LED drive currents, the PCT quickly and easily does the following:

Shows all critical LED design parameters, such as luminous flux and efficacy, for selected LED models
Performs de-rating calculations based on junction temperature (Tj)
Calculates LED valuations, such as lumens per dollar (lm/$)
Estimates simple LED design parameters, such as the number of LEDs required and total power consumption

The PCT uses specifications and characteristics from LED data sheets to accurately compare LED parameters with changes in flux, price and junction temperature. The PCT can compare up to three LED models side-by-side to aid in making critical design choices.
