Side switch is the big limiter here.
Convoy T2 is really a great light, imho, and it’s not huge, but a bit fatter than some AA sized lights. If you can live with that and the tail clicky then you can add one of the screw-on clips to the tailcap (the clip that comes with it will probably come off in pocket carry sometimes and it’s not a deep carry…lots of great emitter choices and pretty solid run time and respectable brightness.
Similar with fewer emitter choices but a smaller body size is the Eagtac D25. They make pretty good lights…had a couple years ago that were favorites but they quit making them. https://www.eagtac.com/index.php/product/d25a-clicky-mkii/
If you can find a Rofis R2 it would also be a solid choice but they are out of business now and only had non-high-CRI emitters, but the neutral white version was pretty decent. It’s a rotating 90° angle head but it’s pretty dang stiff so if you want to keep it straight it will stay straight. Mag charging, uses any battery AA/14500, magnetic tail, deep carry clip, decent. Side switch, decent simple UI. Might have to look to find those now, but they used to run between $45 and $55……SkyBenTrade on Amazon might still have some. The switch isn’t the stiffest…can rotate it so the clip covers the switch if you don’t want to lock out via the tailcap (has e-lockout as well).
I don’t suppose the switch on the soon-to-be-released updated Sofirn SP10 Pro with Anduril will be pocket-worthy, but maybe. The clip is the standard fare that nobody wants. Sofirn SP10 Pro (AA/14500/Andúril 2) - now available!
Lumintop FW3AA is a little powerhouse but quality is spotty and you’d have to use lockout on it (e-switch preferred but head can be undone also). Wonderful captive clip on it like the other FWxx lights but not quite deep carry and I’ve heard they can work their way out of some front pockets (I don’t use the clip on mine). The similar FW1AA single emitter should be out soon also. Personally I don’t think Lumintop is a good buy anymore…had a few failures myself and have seen several others with friends + threads on here. They’ll usually take care of you…maybe…but to help ensure that, buy from them only on Amazon unless you have to get the jump at Neal’s or something.
I’ve only seen Zebra headlamps but I don’t think I’ve ever heard anything bad at all about their lights or service, but you pay for it.
