Best on a budget - SureFire G2X Tactical Single Output LED Flashlight, 600 Lumens

You cant go wrong with this light if you need robust dependable simplicity. This light is a very good L.E. light. It has sufficient throw in most situations. Aluminum housing stands up to abuse and the simple single mode switch keeps things lowwer stress in higher stress situations. You could get more lumens and beefier construction for alot more money, but for me this is a perfect balance between weight, construction and performance at a pricepoint that is replaceable if lost or damaged.
