I've used a ton of models, and my favorite is by far the Streamlight Strion C4 LED. It's tiny, bright as the sun, and rechargeable. The beam is perfect, and bright white. I carry one on duty, and also have one mounted on the long gun. I've beat the snot out of both of them, and they never quit. I've banged them around, dropped them in water, dropped them on the ground more times than I can count. They keep ticking. Right around $100 if you want both chargers (AC/DC). IMO worth the extra money. I think its a better light than many similar SureFire lights, for less money. Just one man's opinion.
