What those fantastic cells do is make this little light pump out an estimated almost 200 out the front lumens. But the brightness is entirely adequate on alkaline and NiMH cells. This light can even be powered by a AAA cell in a pinch—I've even heard of people using AAAs as their main battery and keeping the cell wrapped up with some emergency money so it won't rattle around.
The tail end:
The UI is simple, and blinky modes are hidden (a good thing in my opinion). The modes are properly spaced in terms of output. The light has no memory, so it always starts out on low, which I like.
My example came with a bit of what looks to be glue on the LED dome, and while I can see its mark in the beam when I try to see it, I decided to live with it and not to send it back. But I know that had I opted to have it replaced, 4Sevens would handle the matter quickly and without trouble. They've built a name for themselves as always taking care of their customers.
And here's what it looks like when it's turned on:
The knurling on the side of the light could be a bit more severe, but it's very much adequate.
The other thing that made this light a project was that I wanted to create artificial pocket wear on the anodizing, and from that experience I can say that 4Seven's anodizing job is top notch.
One thing about this light to mention is that it's not current regulated, but is rather regulated by PWM. PWM is my ocular archenemy, but the frequency that 4Sevens uses in their PWM lights is so high that you can't detect it unless you wave it around.
All in all this is a fantastic light that I highly recommend, especially if you're able to find a used warm or neutral tinted model.
