XB-D LEDs from Cree deliver 139 lumens per watt

Cree, Inc. has introduced new LED range called XLamp XB-D LED, which claimed to deliver twice the lumens-per-dollar compared to other LEDs, in the industry's smallest lighting-class footprint of 2.45 mm x 2.45 mm. XB-D LED are developed to lower prices for LED lighting products by using up to three times fewer LEDs, three times fewer optics and substantially smaller circuit boards than current designs, as per Cree.

"Being a leader means delivering revolutionary, not evolutionary, innovation to drive the LED lighting revolution," said Mike Watson, Cree senior director of marketing, LED components. "With this new platform Cree has fundamentally redefined the price-performance paradigm for our components customers. It's not enough to just make LEDs brighter-it's also about improving product payback and market acceptance of LED lighting."

The XB-D LED delivers up to 139 lumens and 136 lumens per watt in cool white (6000K) or up to 107 lumens and 105 lumens per watt in warm white (3000K), both at 350 mA and 85°C. XB-D LEDs are compatible with Cree's existing XP family.
