I bought a Ultra Stinger flashlight from Streamlight a couple of months ago....
It is the brightest flashlight I have ever seen. It has 75,000 candle power. Rechargeable with AC/DC adapters.
This thing is a weapon, and I don't mean the non-illuminating end. If you shine this in a persons face, they are blinded the same as if you shined a spotlight in it. You can actually feel the heat off of it from about 3 ft, away.
I have dropped in the concrete from about 4 ft. No damage.
I am not a Streamlight rep or anything, just wanted to let everyone know about a product I have been very pleased with. If you need a duty light check this thing out. I paid a little over a hundred dollars for mine with both chargers.
