The Coast HP17 flashlight is essential for professionals and anyone who requires a lot of high powered lighting. A quick cycle switch allows you to select between a high output setting of 615 lumens, a high powered strobe mode, or a low output of 64 lumens. Coast's Pure Beam Focusing Optic System with Slide Focus provides superior beam consistency from spot to flood, with no dark rings typically associated with focusing flashlights, and you can lock the beam focus in any position you want with our Beam Lock System. The Bulls Eye spot beam pattern gives you a great focused spot with a maximum beam distance of 269 meters (882 feet), while producing an outer ring of flood light which allows you to see a broader area to the sides. Built tough, an impact-resistant, lightweight aluminum casing resists rust and corrosion. The HP17 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.
