I've just updated the main review with some additional comments in my discusssion. To wit:
After playing with all my MC-E lights a little more, I have to say the M30 is growing on me. I quite like the smaller form factor in 2x18500/3xCR123A, as it is not that much bigger or bulkier than a standard 2xCR123A. Some of the other MC-E competition can be a bit difficult to carry. And the spacing of the levels is pretty good in actual use, even if their relative runtime performance is less than the competition. I also like the included diffuser. If the PWM on Lo/Med doesn't bother you (and I still personally think that is a big IF), then this is probably one of the better candidates for an everyday duty/carry light in the MC-E class.
I am still not entirely sanguine about the PWM or circuit performance on Lo/Med modes, but I'm finding the overall build size to be more useful for everyday carry. If Olight could improve those two circuit issues (and maybe trim down the size of the tailcap a little further), then this light would earn an unequivocal :thumbsup:. And if they could make the beam as pretty as the ACE-G, they'd get a real :twothumbs.
