That MF02S v2 rating of 6500 lumens is way out there. I see Flashaholic got more reasonable #’s, think 4800 at 30 secs, 5600 at turn on. I’m even surprised it got 5600 lumens at turn on - that’s impressive for a SBT90.2 in a factory stock light.

I’m assuming the short MF02S v2 has 4 parallel cells?

Unless they have higher bin SBT90.2’s now I don’t see 5600 lumens, the GT90 which uses 8 cells and runs around ~30A of current can just manage 5k lumens IIRC.

The MF02S v2 must have a buck driver if the cells are 2s2p, and getting a 30A buck driver is no small feat as we all know. Something doesn’t add up, maybe they found a much higher bin SBT90.2?

for what its worth, Martin’s original groupbuy thread (groupbuy: Astrolux MF02S SBT90.2 (600kcd) ONLINE) has a claim by Astrolux that they are using a “35 amp Constant Current Driver”. I dont see that claim on the sales listing on BG anywhere, so no telling if that ever happened. But 35 amp CC seems … expensive? I don’t know.
