I work for an online retailer that sells LE Duty gear which includes flashlights. For handheld lights my preference is Fenix or Streamlight. The Fenix PD22 is my EDC (Every Day Carry) light that is 210 lumens at its brightest and still fits in my pocket. Takes a single CR123 battery.
For a handheld light it's a toss up between the Fenix PD35 (850 lumens, 2-CR123) or the Streamlight Pro-Tac HL 3 (1,100 lumens, 3-CR123). I do carry the Streamlight Pro-Tac HL (600 lumens, 2-CR123) on my duty belt as a backup to my Streamlight UltraStinger duty light.
For hands free work, I prefer Princeton Tec Headlamps. The Apex has several configurations for AA or CR123 batteries. Fenix just released their HP30 headlamp that runs on two 18650 rechargeable batteries (belt mount battery pack) and produces 900 lumens on burst mode. Just picked one up and will be testing it out.

But I reckon I got to light out for the Territory ahead of the rest, because Aunt Sally she's going to adopt me and sivilize me, and I can't stand it. I been there before. - Mark Twain
