Great "tactical" flashlight - SureFire 6PX Tactical Single-Output LED 200 Lumens Flashlight

Very good tactical flashlight for police or military use or home defense. The flashlight stays in momentary on mode (must keep finger on the button) unless the tailcap is turned, and only has one mode -- high. Very useful if you hear a noise and wake up in the middle of the night and need to check the house and don't want to fumble with a light that has a more complex operation. However, you really need to press hard on the button in momentary on mode to keep the light on. Light goes off very easily if you reduce pressure on the switch even slightly. Overall a very solid product. If you don't need the light for "tactical" purposes, get the non-tactical model with different modes.
Pros: Very bright, clean beam; rugged; simple to use
Cons: Momentary on function is slightly too sensitive
