I’d look for reviews here and elsewhere.
They’ve been coming out with an assload of new lights, lots of which I never even heard of ’til I’d poke around their site on AX. The ones made known here, like the C8x series, the SP10s (nil/A/B), etc., were all reviewed here in one form or another, so any quirks would be known. Unless the spex change without notice, of course.
Eg, there’s the old C8F and the new C8F. Old, XP-G3s and tailswitch, tendency to cook the G3s when left on turbo with a beefy battery. New, XP-Ls and sideswitch, souped up thermal everything. Yet the same designation.
There’s the SP10/-A/-B, and to further confuse things, the black B which turned into the black A only with the same UI as the Bs, only now even that’s different.
So depending who’s selling it, you can get an “XYZ” but not know if it’s old or recent stock, thus if it’s version 1, 2, or 3, all of which are slightly or significantly different.
Nice thing about Sofirn is that they listen to feedback, so changes might very well be for the better.
The SP32A is nice and bright, especially for its size, and has ramping, but I kinda prefer the discrete modes.
All their C8s are wow, redefining what the C8 used to be.
I’ve been “converted” from generally dismissing AA lights (and especially AAA lights), but the ’10B is really nice.
Generally, I don’t think you can go really wrong with a Sofirn light. You might have a gripe or two, but I haven’t yet seen anything that’d be a dealbreaker.
