Olight M31 Triton Problem

Aw man... I dropped my Olight M31 on the floor. Now I only get low. Loosening and tightening the head don't do anything. I tried new batteries. Still just low. This stinks, I love this light to death. What's my recourse guys? Any hints? Anybody have this happen? Who to contact for warranty service/replacement?

Oddly enough, after cleaning the threads real well and repeatedly trying the light, it seems to be back to normal. It doesn't seem to be the drop that did it, rather the connection of the body to the head. The end threads of the body are pretty rough, I cleaned them with some alcohol and the gold ring in the head that the end of the body makes contact with to change modes in the head. That ring is pretty worn from my repeatedly changing modes, but it's working smoothly now.

Still a great light and I love it, had my faith a little rattled there, but she's back in action.
