The HP5R rechargeable flashlight has a beam distance of up to 172 meters (564 feet), making it an excellent duty light for all types of tactical, rescue and law enforcement professionals. Coast"s Flex Charge Dual Power system allows you to charge using AC, DC or USB power sources and also operates on a AA alkaline battery, allowing you to continue using your light, even without access to power. A second rechargeable battery pack is included which can be charged outside of the light so you can always have one ready. A quick cycle switch allows you to select between a high output setting of 181 lumens, a high powered strobe mode, or a low output of 17 lumens. Coast"s Long Range Focusing Optic System with Speed Focus Control provides superior beam consistency from spot to flood, with no dark rings typically associated with focusing flashlights. Built tough, an impact-resistant, lightweight aluminum casing resists rust and corrosion. The HP5R 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. Tested and rated to ANSI/FL1 standards by an independent laboratory.
