Features: Olight released dual-light source flashlight with the Arkfield. The Arkfeld easily switches between the cool white light and the UV light with the flip of a switch. The intuitive interface is a perfect control panel to use and switch between lights and modes. The new Arkfield now offers a UV light source, rather than a laser pointer, to check for invisible-to-the-naked-eye biological stains, counterfeit bills, fluorescent agents, and hotel cleanliness. With its 5-level power display, you can easily check the remaining battery power any time. Need to use both your hands? No worries, this model features a magnetic tail that you can attach to any metal surface. Use this flashlight for outdoor use, emergency situations, or for your everyday work! Mode: Output / Runtime
