With its darkness-piercing single 800-lumen output the Nightstick TAC-410XL Xtreme Lumens Rechargeable Polymer Tactical LED Flashlight is aptly named. It puts a powerful and highly functional illumination and safety tool in your hand that is easy and intuitive to put light exactly where it's needed. Outfitted with a powerful white Cree LED and a smooth, deep parabolic reflector, the flashlight outputs a bright beam designed for a long throw. The light's momentary or constant-on activation is controlled by a simple and intuitive rear push button that is easy to find and use, even in cold and wet conditions.

Nightstick built the light with a 1" diameter handle to make it compatible with a wide range of third-party scope rings and helmet mounts and a 1.25" diameter head that makes it compatible with a variety of filters so you can change the color to suit your needs. Weighing just 4.9 ounces with the included rechargeable li-ion battery, the light won't add excessive weight to your rail if you weapon mount it or head and neck if you opt to wear it on a helmet. The housing is made of lightweight and durable glass-filled nylon polymer to withstand high heat and abuse on the job. The housing is also sealed to an IPX7 rating, making it waterproof and submersible to 3.3' for up to 30 minutes, and it is impact resistant to almost seven feet so it can handle a fall better than you.

Included with your light is a charging cradle that charges the battery in the light, along with a 110 VAC US house outlet charging cord and a 12 VDC car/vehicle cord for your car, work truck or cruiser so you can keep your light lit all day—but in a pinch your light will run on two disposable CR123 batteries using the included battery cartridge.
