I have zero experience with Olights. I was going to try to use a piece of rubber or maybe a rubber stopper to push against the bezel and rotate it.
The lens is the only thing I don’t like about this particular model. Everything else about it seems perfect. If I were going to use it as a headlamp I would keep the TIR, but I’m going to be using it as an everyday carry light, so I need more distance.
No one seems to take these Olights apart for some reason. I can’t find any internal pictures at all.
