Thanks for the suggestions, but at least based on what I can find it looks like neither of these lights can hold the output that I want. Not a 100% sure on the MF01 tho. I found this thread here and it doesn’t look promising:
Even after the mods it could only hold a 1000lm, just. Not sure if this light was from the first batch, and how the current stock lights compare to this modded one.
I looked at so many reviews and the M3’s ability to hold ~1400lm basically forever is starting to look better and better. I wonder if it could hold a bit more if it had a better UI with some extra steps.
