I've been using a
Maratac AAA for a while and its a surprisingly good light.
Specs look impressive for an AAA powered light.

It replaced my Fenix LD01 as a keychain EDC. The Maratac low is much lower than the Fenix, its significantly smaller, has a more secure clip, and the beam pattern is wider so I find it a bit more useful. The only problem is the slightly noticeable PWM on med. and low which is not an issue on the Fenix. But overall its a good light for the price.
