Very compact LED (the die is mounted on a chip 2.45 mm square opposed to 3.45 mm square for XP series) introduced in February 2012, promising lower cost. Should provide similar brightness to XP-E LED's. First available units were warm white with Q2 brightness bin (at 350mA). Can be driven up to 1000mA.

Should provide similar brightness to XP-E LED's. First available units were warm white with Q2 brightness bin (at 350mA). Like the XT-E, the LED's are binned by lumen output at a temperature of 85 degrees C instead of 25 degrees like earlier LED's. Since the datasheets indicate 14% higher output at 25 degrees, the output numbers from Cree have been increased in the table below for 25 degrees (also see [[XB-D output]]) to make it easier to compare LED's. Can be driven up to 1000mA. [http://www.cree.com/products/pdf/XLampXB-D.pdf Datasheet], [http://www.cree.com/news-and-events/cree-news/press-releases/2012/january/120111-xbd press release]. | ||
