Next generation of lighting class leds?

According to the company, the XLamp XB-D led has twice the lumens per dollar of other LEDs and has the industry's smallest lighting class footprint of 2.5 x 2.5mm. It is 48% smaller than Cree's earlier XLamp XP package and is suitable for lighting applications where high lumen density and compact light sources are required. Mike Watson, Cree senior director of marketing, led components, claims the innovations behind the leds can significantly 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. "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 350mA and 85°C.
