So I got a new light today and it has some trouble turning on and when it actually does come on, it doesn’t stay in the mode. When I took a closer look at the tail of the body tube, I noticed that the anodizing goes all the way to the end. The threads aren’t anodized, but this is the first 18650 light I own that has anodizing all the way to the end. Would this be a problem or could it be a switch thing?
Solved: After tightening everything, wiping it down and trying all my batteries…… it finally turned on when I used my protected batteries. I guess all my unprotected ones are too short. The purple ones in the picture are unprotected Samsungs but my protected ones reach the top of the barrel. That fixed it.
