We replaced our signature Red Ring of Quality with black and subdued the Coast logo to create a tactical style that will fit right into any situation where stealth and concealment are necessary. 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 Fingertip Speed Focus Control 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. Tested and rated to ANSI/FL1 standards, the HP17TAC also features an unbreakable LED and rubberized O-ring for reliable water resistance and durability. Backed by Coast"s lifetime guarantee against defects in materials and workmanship.
