Hi all, I just stumbled across these lights and didn't know they existed until now. I don't really see a ton of information out there on them. Does anyone have any experience with these? How do you like them? From what I have read, it sounds like they could be pretty good. How is their durability? It seems like they work well as weapon lights also. How do they compare to the well known quality brands here like Surefire, Malkoff, HDS, Elzetta, and Zebralight?
