The F1 from Led Lenser is definitely an EDC flashlight you should be checking out. The F1 puts out 400 lumens on its high setting from one CR123 battery. The military standard, matte black housing measures just 3.5 inches in length and is waterproof in up to 8 feet of water. The F1 weighs in at a measly 3.6 oz. and comes with a pocket clip making it a perfect EDC flashlight. There are three different settings on the F1: High, Low, and Strobe. It comes with two interchangeable rings. The chrome ring is pictured but it also comes with a black glass breaking ring. We switched out the chrome ring immediately because we prefer the all black look. The cheapest we have found this light is at the link below. If you are unfamiliar with Led Lenser their parent company is Leatherman and both put out quality products that are backed with excellent warranties.
