FandyFire 2x18650 2x26650 4x123A
Waterproof means "submersible"?
It's supposed to be a dive light apparently but it's the usual case of designing a dive light by a non-diver.
There is no switch. You put the batteries in just before you dive. How convenient :) It says it's tested to 50 m. It would appear to be a fairly floody light so not so good for anywhere other than clear tropical waters but who needs 1000 lumens (or whatever the actual numbers are) in clear tropical waters?
I don't see any reviews so it's just a crap shoot at this point as to whether it actually can go to 50 m. When I think of dive lights I don't think of Fandyfire for some reason :)
