Cree SC³ Technology Platform yields brighter, high-voltage versions of XT-E and XM-L LEDs

Cree Inc of Durham, NC, USA has announced the availability of brighter XLamp XT-E and XM-L High-Voltage LEDs to provide manufacturers with more efficient, cost-effective components.

The new LEDs leverage the SC³ Technology Platform, which also powers the existing XLamp XB-D and XT-E LEDs. Built on Cree’s silicon carbide (SiC) technology, the platform features advances in LED chip architecture and phosphor, as well as a new package design.

The new, brighter XT-E and XM-L High-Voltage LEDs deliver up to 22% more lumens than their predecessors, and are designed to use lower-cost, higher-efficiency and smaller-size drivers than standard-voltage LEDs. By providing comparable performance to their standard-voltage counterparts, they eliminate the trade-off of optimizing for either LED efficacy or driver efficiency, says Cree. The new high-voltage LEDs provide more design options to address a wider spectrum of small indoor and outdoor lighting applications, such as accent lights and replacement lamps, the firm adds.

“Leveraging the power of the SC³ Technology Platform, Cree has fundamentally transformed price-performance with the XB-D LED, set new performance standards with the XT-E LED and - with the introduction of the new XT-E and XM-L High-Voltage LEDs - redefined performance limits for LEDs of this size,” claims says Mike Watson, senior marketing director, LED components.

The XT-E High-Voltage LEDs can deliver up to 357 lumens at 3W in cool white (6500K) and up to 275 lumens at 3W in warm white (3000K), both at 85°C. The XM-L High-Voltage LEDs can deliver up to 647 lumens at 6W in cool white (6500K) and 555 lumens at 6W in warm white (3000K), both at 85°C. Samples are available immediately and production volumes are available with standard lead times.
