Surefire M6 Guardian LED Flashlight is an upgrade of the Surefire M6 Guardian - one of the original incandescent heavy-hitters. The Surefire M6LT Guardian Tactical Flashlight features a high-performance LED light source and a Turbohead TIR lens that, together, produce an 800-lumen extended-reach beam, powered by six 123A lithium batteries. The Sure Fire M6LT Flashlight has an high-strength aerospace aluminum body that is deeply machined to provide a secure hold with cold, wet, or gloved hands, and finished with Mil-Spec hard anodizing for excellent corrosion, scratch, and abrasion resistance. This Surefire Flashlight features simple tactical switching: press the tailcap switch for momentary-on, twist the tailcap for constant-on. The Surefire M6LT Guardian Ultra-High Single-Output LED Flashlight puts 800 lumens of optic nerve-quivering power in your hand!
