+1 on the Fenix flashlights - all kinds to choose from and I like all the ones I have -- from itty-bitty to beastly lumen output (TK35).

The one that most impresses me so far - for being small and bright - is the Fenix E11. A single "AA" battery gives you 105 lumens.

Prior to being introduced to Fenix I was loyal to Surefire (but none that were EDC).
