It’s the highest performing LED I have out of the 5 I tested with the lens on…it’s the only one I took the lens off of…
The other 4 barely made 4800 to 5200lm at T/O then I got 358Kcd. But now out of the same exact light, battery and driver set-up it is now doing 408Kcd just swapped the board and LED out… proof enough for me…this is an actual reading the meter isn’t locked on to the highest burst…
T/A maukaka calibrated tube YMMV…
