This is an extremely important thread about a POS light made to fail but its not under “Dive Lights” so I am sharing the link here.
Everybody (including me) have had nothing but problems from this light and I hope I can save people hard earned money by sharing this thread in hopes people read it before purchasing.
I was considering a Trustfire, but then I read reviews.
The Trustfire TR-J1 only has 1 o-ring where the head screws in. From SB review :
"Speaking of o-rings, the tail-cap has 2 rings, while the other end has just one (the other ring is just for friction for the switch). Seeing as this part isn't unscrewed as much, I guess it'll suffice, though I guess 2 would've been better, though there is an extra groove in it."
(cf. CPF review)
What I heard is the tailcap current on Hi is between 2.2 - 1.8A (cf. CPF). So it's really not living up to its potential.

TrustFire TR-J2 is also ~2A at tailcap. asked a salesman at Alibaba.
