Stinger HL (high lumens). Best light by far Ive ever used. Very bright at 800 lumens, far reaching and yet floody enough to search a building. It starts at 800 then if you hold the button it ramps downward two lower settings. This is useful when you know you'll be on traffic control for a while and you need your light for 4 hours....ramp it down to the low setting. Still just as bright with the cone.
I've used the Surefire 6P's and they start from the low setting and go higher...dangerous for me. I need bright light first off. Don't get me wrong....the 6P is a great light, but super expensive if you want the good/brighter ones. But then you get into battery issues. They usually all take the CR123A's only. You can go with the "Solarforce" generic brand, which I have, but still the rechargeable 18650's can get expensive.
I just went through this the last couple months. I decided to stay with the Stinger and bought the HL model. Small enough to carry on a belt. Batteries are 20 bucks or less, so I have a couple spares charged in my go-bag ready to go.
Can't beat this light. The Stinger HL is about 110 bucks on Ebay or Amazon.
