Cree Inc. unleashes the XLamp XT-E white LED that boasts twice the lumens-per-dollar of other LEDs. Based on a new silicon carbide technology platform, the device is targeted at low-cost LED adoption and enhanced efficiency in LED lighting systems.

The XT-E LED more than doubles the lumens per watt of the XLamp XP-E LED family—providing up to 148lm/W at 85°C (or up to 162lm/W at 25°C) at 350mA. The XT-E LED comes in a 3.45 x 3.45mm XP footprint and can be used for almost all lighting applications, according to the company.

The white LED flaunts a 3.45 x 3.45mm footprint.

By leveraging the XP footprint, customers can easily incorporate the XT-E LED in existing XP LED designs to shorten the LED fixture design cycle and improve customer time-to-market. Additionally, since the XT-E white LED is a successor product to XP-E High Efficiency LED, the application for ENERGY STAR qualification requires only 3000 hours of XT–E LED LM-80 data, instead of the normal 6000 hours.

The XT-E white LED delivers up to 148lm and 148lm/W in cool white (6000K) or up to 114lm and 114lm/W in warm white (3000K), both at 350 mA, 85°C.
