Truly the original, the 6P was the first hand-held flashlight ever produced by SureFire. Initially manufactured in 1987, it has consistently remained the best seller, and today is the rock-solid cornerstone of the now legendary SureFire Personal Light series. All of its parts are machined from top-quality aerospace-grade aluminum. It boasts a hexagonal anti-roll bezel, patented lock-out tail cap and virtually unbreakable Lexan lens. It's powered by two 123 lithium batteries (included) and operates with an innovative P60 lamp assembly that produces an astonishingly bright 65 lumens of light, with a 60-minute run time.Batteries included.
