I too have been searching for a better EDC light.. but my search was waylaid by SR-101, SR-77, & Infi.
I've ditched MagLite 2xAA bulb types long ago.. the bulbs burn out/break way too fast.. not enough light for the weight/size carried.
SureFires, arguably among the best money can buy.. but the specialty Lithium batts are kinda out of my league for what i wanna do.
So I'm on the Hunt for a good LED, small, pocket carry, long batt life w/ normal AA or AAA.
In the meantime i'm packing a humble lil Dorcy 1AAA LED (~$7.99 @ Walmart)
