Nightstick's TAC-510XL rechargeable flashlight is made of glass-filled nylon polymer and uses a Cree LED rated at 800 lumens. Along with the LED, this light's high-efficiency deep parabolic reflector creates a usable beam rated at 205 meters. The push-button tailcap switch provides momentary or constant-on functionality and is programmable for one touch high, medium, or low-brightness settings as well as a disorienting strobe. The TAC-510XL runs on a rechargeable lithium-ion battery or a pair of CR-123 batteries. A charger that can run on both a standard wall or car outlets is included.
