XLamp XT-E White

Highest-performing lighting-class LED

Cree XLamp XT-E White LEDs are the highest-performance white LEDs available. The XT-E LED delivers twice the lumens-per-dollar of previously available LEDs in the popular XP footprint. By leveraging the popular XP footprint, customers can easily incorporate the XT-E LED into existing XP LED designs to shorten design cycle and improve time to market.

Built using the latest generation of Cree's silicon carbide based LED chips that deliver higher flux and efficacy, the XLamp XT-E White LEDs set new standards of efficacy, light extraction and quality. Designed to accelerate LED lighting adoption, the XT-E LED delivers up to 148 lumens and 148 lumens per watt in cool white (6000 K) or up to 114 lumens and 114 lumens per watt in warm white (3000 K), both at 350 mA, 85°C.

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.
