Beam shots…… I just now finished my MF02 70.2. If lexel was here I’d give him a huge hug
VS
Mateminco MT35 with a xhp35 E21A 18 AWG wires, stock driver 2280 Lumens after 10 seconds
Distance is 55 feet. Pretty self explanatory. One pair of the beam shots is with manual seetings and one other pair witis with auto camera settings.

Looks like an awesome combo! Can you take a lux measurement?

Ya, I think I can, I have only measured LUX on smaller throwers from 3 meters away. I’m still a little confused what the proper/Ideal distance should be for large reflectors throwers (70mm in this case) I should be farther away from the sensor? 10 meteres? What’s the ideal distance for the BLF GT? I’d like to measure my GT before and after a (xhp35 E bin 6000k) swap also.

I would guess you need 7 or more meters to measure the MF02. Not sure about the GT.

With MF02 and GT I got best throw numbers at 15-20m
