Single RCR123 (16340) flashlight?

[ArchAngel]

I've got one of these on order. Looks like the kind of thing you are looking for.

Anyone order (and receive) a four sevens Atom yet?

They were supposed to ship last week.

Just got the notice mine is shipping today.

I can't recommend the Eagletac D25C enough. It's a tiny little light that is capable of taking a 16340 and will produce 770 lumens according to selfbuilt on candlepower forums. I've carried mine for almost a year and haven't thought about another light since.
