Engineered to be your ideal everyday carry tactical illumination tool, the black Nightstick USB-558XL USB Tactical Rechargeable LED Flashlight offers you a powerful maximum output of 900 darkness-piercing lumens with two lower-lumen outputs and a disorienting strobe mode. Additionally, it offers rechargeable convenience from a wide variety of sources. A USB charging cable is included that allows you to use a standard USB computer port, the USB port in your car, or a 12 VDC car/vehicle and 110 VAC wall plug adapter (similar to the one you use to charge your phone and tablet). The light's integrated charging port is covered to protect its IPX7 rating, and an LED indicator lets you know when it's charging and fully charged.
