I got this light today, to put an XHP 70 led in it, but I have a couple thoughts on the stock light. Maybe they are not worth much, as thoughts go, but here they are.
The deep reflector sits up a little, above the led base. In the beam, I can see artifacts in the spot. I think that if the reflector was repositioned, the artifacts might be lessened or eliminated. I think it needs to be moved, but there's no real easy way to do that.
My camera does not take good beam shot photos. It tends to just blend and smooth everything, but in this shot, you can see a little of what I am talking about. I can see it much heavier and much more noticeable, with my eyes. Enough that I would not want to keep the light, because as you increase distance, the artifacts are just going to get bigger. This was at about 10 feet.
The next thing is with the battery carrier and the tail cap spring.
The carrier is 2S/2P and it's a sturdy carrier. You can put it in the light either end up. Both ends are the same. Positive and negative are both on both ends.
That's fine with me, but my issue is with the tail cap spring.
See, with the positive and negative on both ends, the body isn't needed, except to just hold the battery holder in place and put pressure on it, to make both the positive and negative touch the head. This spring touches the Positive contact on the other end of the carrier. I know it's isolated, but... what if one with poor ano lets the spring make contact to the tail cap and the body? What if someone playing around with it doesn't realize and ends up making it contact the tail cap/body? Well, it is a direct short waiting to happen. That center portion of the spring shouldn't be there. It should have been bent so that it missed the positive contact. It could have been done better at the factory, when designing it.
Hey, I'm just sayin... I think it's a very slim long shot that it could short, but why take chances?
I will be modifying that spring, or at least covering it, so it cannot contact the positive terminal of the battery holder.

Maybe the spring is some new type of non conductive wire, not. There must be a lot of these lights out there that the manufacturer has put a lot of confidence in there anodizing as a first class insulator.
Looking at it closely, is it in some sort of plastic sleeve, the spring that is in the base?

I thought that it might be, but I do not want to heat the tail end, to get it apart. I scratched it with a pick and I don't think it's plastic, but without taking it apart, I can't be sure.

It sounds like the XM LEDs won’t really be suitable for flashlight use. Pity…
