I see I am a few badges behind...
Here are a few pics of my favorite EDC lights.
I do not have heavy lighting requirements for EDC, so I can get by with a good AAA light like the
FourSevens Preon Revo SS:
For more juice, I grab the Zebralight SC52 AA:
I like the headlamps too, and have a Fenix HL30 (AAx2) for use around the house, Fenix HL50's (AA) in my workshop and in the car, and a Zebralight H52 (AA) in my work bag.
