I have discovered an unusual bug, I dont know how to solve it yet. But I know how to cause it.
It was seeming like every time I opened one of these lights, something would go wrong. I had one set aside for over a month beause I could not figure out why it stopped working. I bought another one cause I thought the first one had a dead driver. Now the New one acts just like the first one.
bottom line
These two lights only work properly if I do not overtighten the bezel. Unfortunately for my OCD, that means I cant line up the logo on the bezel, with the switch button, even though they came lined up originally.
(unless I can make peace with using loctite to hold the bezel in place after backing off the threads a turn, which will leave a “big” bezel gap… aaargh!)
in any case they are working properly atm, one is 3000k 219b, the other 660nm red. I run them on Eneloop only.
rant:
I dont really like sideswitch lights… given my vision challenges, a tailswich is easier to find. There is a previous model of this light, with tailswitch and a screw on clip, that I prefer… But I suspect it also has PWM on the low mode. This model has a tailmagnet, that I have not yet removed. I consider them a nuisance. I also have not added a battery sleeve yet, to stop it from rattling so easy… oh and, one of them only works if I make sure to get the head a bit extra tight… seems I screwed something up in there too… these guys are some of the worst to work on, of my limited experiece, and also one of the hardest to open, and the bezel has the scratches to prove it… oh well… still fun when they work.
