I’ve just had it apart, not sure I can push the pill further into the head, its hard against the reflector, which is hard against the lense and bezel, and I want all of them tight against the o-rings.
I turned my attention to the tail cap, it has a brass button sitting on the spring, retained by a plastic top hat and a brass ring. All these jut out into the tail cap.
When I stripped it, I got the next suprise, the spring is not soldered to the board. As I stripped further, I got another suprise when the clicky flicked across the cab of the van……. Yep, that’s not soldered either :~
This thing as is will not pass much current I believe, and would probably flicker if shaken.
I’ll add photos when I’m not at work, but I first thought of flipping the brass retainer, however it first needs relieving as it would link out the switch (lucky its brass huh?). So my plan is to relieve the retainer, do away with the button top and top hat, solder the whole switch assembly, then go from there.
I did manage to get both an inr 26650 and a grey ultrafire to light it, but not with the tail cap tightened down, and buying specific short cells is not happening, I want it able to run what ever I put in.
The pill fit is really, really poor by the way, I’m thinking of trying to us Ali foil like ptfe tape on a plumbing fitting along with thermal grease, or if I decide I really like it, I may see about getting a new pill made, depends on the threads in the head I suppose.
