This is the famous "Stinger" model flashlight by Streamlight. Super-tough non-conductive nylon polymer with non-slip grip makes this an ideal flashlight for fire/EMS. It fits easily in a turnout pocket, and the high-visibility yellow color makes it easy to find on scene. Rechargeable 1,000 times, and a full 15,000 candlepower brightness, this great tool only weighs 8.7 ounces! DON'T use it to check pupils, though, its way too bright for that. Somewhere on the yellow part of the flashlight, write your ID number or name with a black felt pen. That makes it easier to find if someone "accidently" puts in in their own pocket.
