My lighting EDC, especially when I am out in the woods, is some sort of headlamp. They can be carried in the hand, as well as worn on the head, and they are often better deployed in that manner. I prefer something using AA, or increasingly, 18650 batteries. Current lights often offer variable light levels, so you can count of long run times with reasonable illumination, or really bright light for short periods.

I have used D-cell Maglites in the past. They were good items in their time, virtually the first quality flashlights.
