It arrived fast and well packaged. It was in perfect shape with not a scratch on it.

The Good

3x XM-L2 (it stated XML-T6 so this was an upgrade)

The size! This is a great sized light. I had seen it advertised before but for some reason I always thought of it being the size of the regular TF 3xT6. This light is much smaller. It is like a slightly longer version of a C8.

The handle is perfect. It's very comfortable in the hand and has nice knurling.

The user interface (Modes) are super. It's a magnetic side switch with ramping. Slide the switch up and it gets brighter. Slide it back down and it gets dimmer until it turns off. It doesn't get any simpler than that.

It's not only waterproof but you can actually dive with this light. I didn't take it diving but I know another member who has and he had his down to under 100 feet with no problems at all. The O rings are all very nice and solid and the lens is very thick.

The Bad

The pill does not screw in place. although it's a large pill and fits tight, it still should have been a screw in pill for better thermal transfer.

The average.

The lumen output is only average. It's only actually 1,800 lumens but for the size of the light I think that is actually very respectable.


Conclusion


I actually like this light a lot. If you think about this light in context of other small multi-emitters I think it holds it's own very well and exceeds them in some aspects. The dimming driver works really well and with two by 18650 it gets good run time. I love the size of this light. It's really a very usable light. It's small yet decently powerful. It could get rained on night and day, you can drop it in the lake or play with it in the pool if you are not diving with it. I really expected this light to be much bigger and I was pleasantly surprised to find that it's such a small light.


I'm not going to go overkill with the pics just this one. This really lets you know how small this light is. The light on top is a TF 3xT6 and the bottom light is a small C8.
