Cree bins individual models of LED on the basis of total flux or light output, typically measured at 350mA. Bin numbers might be P4, Q2, Q3, Q4, Q5, R2, R3, R4, and R5 with each bin being about 5% additional flux. The P4 is 80 lumens, a Q5 would be 107 lumens, and the R5 bins are 137 lumens. At higher amperage than 350mA, the brightness goes way up, with the XP-G producing 3 times as many lumens at a maximum current of 1500mA. | Cree bins individual models of LED on the basis of total flux or light output, typically measured at 350mA.
