The Coast XP18R Rechargeable Dual Power Flashlight offers a turbo mode that emits up to 3,650 lm in addition to standard light modes (low, medium, and high). With Coast's Rechargeable Dual Power technology, the flashlight runs on a Coast ZITHION-X battery (charging cable included) or standard alkaline AA’s (purchased separately). Power is monitored in real time with a battery life indicator, enabling users to be ready at all times. Users are also able to transition between a spot and flood beam with a push or pull of a finger via Coast's Slice Focus system.
