Looking for small 16340s to fit glo-toob

[Vermonter73]

I'm wondering which 16340s are the smallest so I can fit them in a glo-toob. Thanks.

I can't really help you with this other than to say that AW makes the label removable, which might give you a little bit more clearance.

Because of length or width?

DX has some LiFePO4 which has practically same size as normal CR123A - same width and only a hair longer.
Being LiFePO4 they're safe to use without protection circuit but of course runtime isn't as great as with ordinary LiIon.
