I dunno. Doesn't Fenix offer the TD40 (something -40) that runs on a scad of AA's and only has 2 modes?

Apparently 4sevens.com has some nice inhouse lights. Their Quark like is getting nice reviews, but if you go that way, do be careful - there are two types: "tactical" with 2 light levels, and "normal" which is like Fenix.

Streamlight is in the same price range, sort of. Usually only have 1 mode

Surefire can be 1 or 2 modes, but of course run about 3-4x that of a Fenix.

Olight is a rip-off of Fenix, maybe even from the same factory. The Leatherman lights (I think at Costco) are also Fenix rebrands, IIRC. Nitecore has some good solid offerings (look online, but I know 4sevens carries them too).

Anyway, go peruse candlepowerforums.com if you want more info. I'd spend a little time with the search button first, as first time posts of "help me!" are on there nearly weekly, usually repeating the previous week, and some members get a bit testy.
