Streamlight SL-20LED is what I use for my work flashlight. Rechargable, very bright clean beam, comfortable to hang onto, and it can really take a beating. (or give one, depending on how you look at it!) I like having the LED option for close up stuff, like looking at papers or writing notes or something. Plus, if it goes dead on the regular light, you still get about an hour of usable light from the LEDs. If you don't want the LED you can get the same light without it for a little less $. That is the SL-20. If you are not going to beat it up, then you can get the SL-20P, which is a composit, or plastic, housing.
Try one! You will love it!
