With the XB-D and XT-E LEDs, Cree began binning their LEDs 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.

Brightness Bins for Cree XB-D at 25° C
Bin	350mA 100%	700mA 175%	1000mA 222%
Q2	100-107	174-187	220-236
Q3	107-114	187-196	236-253
