With the XB-D and XT-E LED's, Cree began binning their LED's at 85° C instead of 25° C. For easier comparison, the Cree and Brightness Bins pages show the output at 25° C, but here are both. According to the XB-D datasheet, the output is 14% higher at 25° so the numbers for 85° are just multiplied by 1.14.
