Each click represents 1 degree C. What I did in the video was just an example, I cant remember what I actually set it too. 70C is going to be a “hold by tail cap” kind of hot. I’ve had lights in bench tests survive roughly that though. Probly not good for real world use.

A difference of 0.8mm could be the make or break on this light. Convoy L6 has the same problem. I think with this light much of the issue could be the spring bypass on the battery + end. In my E07 is its very hard and stiff. Looking just now at I noticed it concaved battery top as a result. The solder joint sticks out past the spring, and the travel is also reduced by it somewhat. Eliminating it may not be easy either, as it looks like the wire comes through a drill hole in the center vs a pad to spring contact.
