This is just a very quick review of Trustfire's heavy duty diving light. Loaded with a pair of 26650's it is just short of of two pounds so it's a very hefty light. Everything on this light is extremely solid. Great O rings and design. The pill is very thick as is the rest of the light. The lens if very thick plastic or should I say some type of plexiglass. It's not going to break that's for sure. I like the way the driver is set up. It's soldered into a brass ring that screws in place, so it's a great contact point and isn't going to be flickering in and out no matter what you do. The beam profile is actually very nice as well. The reflector is essentially like a SRK 3x. This does not have a tailcap switch so you change modes by twisting and quckly twisting it back. It works fine and again is fairly well designed. Output was pretty good as well for the stock driver. (not that I would leave any light stock). I can't find the charger for my good camera so I didn't take a lot of pics but there are plenty of them on-line if you are interested. I'm not a diver so I don't have any experience taking this light down into the depths but considering the way they have the O-rings set up I'm pretty sure it would be good for a long way down. I have owned maybe a dozen other So called diving lights and I don't think any of them come close to this light as far as the O-rings go. Somebody really wanted to make sure this light could really go under water and not just get wet and be OK. I see this light selling for around $80 which really seems a little but much for a trustfire light, but this thing is built like a tank with no design flaws that I could find, which is very rare in any flashlight no matter what company puts it out. I have now modded mine so it has 3x XHP-50 and a BLF FET driver and it handles them and their heat output very well.
