I’m using an Olight I3T and it’s fine. I’m mostly looking for options for hat bills. Doesn’t have to be AAA but it can’t be too heavy. Tail switch, side switch or head twisty is good.
EDIT: I went looking for what might work. I have a few options already I guess :doh: if i can find correct batts and clips.
Now I’m thinking 'bout those Boruit or Rovyvon plastic types …with mode memory! or <3 modes.
Just like any light, the best one is the one you got on ya. 
But there are alllll sorts of other considerations before any answer can be given. Floody or throwy? Need brightness? Runtime? Color rendition? Color temp? Etc.
Use case scenarios: Two leashes in one hand and a plastic bag wrapped around the other.
Two leashes in one hand while trying to clip them onto the curs.
Getting the mail.
Passing through the early morning garage.
I think Floody. Brightness is not too important but but ya know …moar! Runtime will be short spurts of On then Off. Not sure about rendition but maybe right on the bubble(?) not too rosy, not green. Temp not above 5000k.
I suspect the “Etc” is mostly beyond my understanding.
I pulled out an SC13 w/519a’s and while it just wasn’t right in the pocket the balance and weight seem to make it a good fit on the hat so far.
I posted my Q in haste…yet I’m still interested in others experience.
Hmm, then maybe the Acebeam Pokomon 1AA would work.
14500/AA, so slim.
Fairly floody, really nice even beam.
Reversible clip.
All-around nice light.
Oh, comes with a 14500 Li cell that has onboard usb-c charging.
