With a maximum light output of 1075 lumens, the Coast HP550 flashlight is not just bright; it also uses Coast's Pure Beam Focusing Optic System with Slide Focus to harness the light and create a superior beam quality from spot to flood. The Bulls Eye spot beam pattern gives you a great focused spot with a maximum beam distance of 351 meters (1151 feet), while producing an outer ring of flood light which allows you to see a broader area to the sides. The flood beam is broad and consistent, giving you a clear field of vision not seen with typical focusing flashlights. A quick cycle switch allows you to select between a high output setting of 1075 lumens, or a low output of 53 lumens. Built tough, an impact-resistant, lightweight aluminum casing resists rust and corrosion. The HP550 also features an unbreakable LED and rubberized O-ring for reliable water resistance and durability. Backed by Coast's lifetime warranty against defects in materials and workmanship. Tested and rated to ANSI/FL1 standards by an independent laboratory.
