120 to 150 from a q2 :thinking: that cant be right ....i hope it is cuz that would mean that my q4 on the way would turn my p3d into 200 lumens then
but that doesnt seem right not till the r4 comes anyway ...
Theoretical lumens from different Cree bins at different current based on Cree's Datasheets of the XR-E LEDs
Current vs. Luminous Flux
@350mA - baseline
@750mA - 180% over baseline
@1000mA - 220% over baseline
P4-bin @350mA: 81 - @750mA: 145 - @1000mA: 177
Q2-bin @350mA: 87 - @750mA: 157 - @1000mA: 192
Q4-bin @350mA: 100 - @750mA: 181 - @1000mA: 221
Q5-bin @350mA: 107 - @750mA: 193 - @1000mA: 235
R2-bin @350mA: 114 - @750mA: 205 - @1000mA: 250
R3-Bin @350mA: 122 - @750mA: 220 - @1000mA: 269
R4-bin @350mA: 130 - @750mA: 234 - @1000mA: 286
max @350mA: 136 - @750mA: 245 - @1000mA: 299
Plus that Japanese site uses estimated lumens conversion - not actual lumens recorded from a light meter.
