When I first started almost 25 years ago I carried a 2AA minimag as a backup light and a department issued 4D maglight. Recently my duty belt lights changed again. I went from a Fenix LD20 and a Jetbeam PA40 to two Klarus lights. I currently carry the XT2C and the P2a. I absolutely love the U.I. on the XT series lights. I carry the P2A as a backup for it's simplicity and because it takes readily available batteries. It's simply amazing when you look back and realize just how far flashlights have come. Just wondering what you guys doing the same type of work carry on your belts.
