Another +1 for the Fenix lights.

My current EDC is a PD35 an LD01 (AAA). I decided that I needed a LOT more throw for the primary light last Fall. The PD35 was an upgrade for a LD20 which was an upgrade for a L1D/L2D/P2D set. The last three used either 2AA, 1AA, or a 123a battery with the same head.
