Surefire 6px tactical flashlight - SureFire 6PX Tactical Single Output LED Flashlight, 600 Lumens

Very bright white light without any shadows exactly when you need it.Simple push of the tail cap button gives 100% of 320 lumens or can twist tail cap for constant on.
Pros: No confusing modes, just bright light when needed
