The PD35 is insanely bright, and offers lower output levels for extended battery life. Good stuff.
My first love was flashlights - before guns, knives and multitools. I now EDC a Fenix E05 (new edition). Its a small AAA, but cranks an impressive 85 lumens for an hour (using a NiMH rechargeable battery like the awesome Eneloop), with lower outputs for extended runtime as well. That's plenty of light for most needs. It will light up the average back yard.
Consider maybe a PD35 in the glove compartment with an extra 18650, plus an E05 on your keys.
I often direct traffic at night (parking cars to raise $ for a charity because I'm a swell guy), and use a pair of Streamlight LED Stingers with traffic wands. They will run on high for a couple of hours, and have a tight, throwy beam. Plus strobe. Strobes are awesome for getting people's attention.
