The "XL" in the Nightstick NSP-9842XL Tactical Dual-Light LED Flashlight stands for "Xtreme Lumens" and it is aptly named.

This multi-function illuminator has three primary outputs with a maximum of 650 darkness-shattering lumens columnated by a smooth and deep reflector that produces a beam optimized for a long throw. A secondary floodlight LED placed at the top of the handle on the side emits 200 lumens of unfocused light so you can more comfortably perform up-close tasks, such as cooking, checking gear, or reading, to get the job done safely and easily. With the needs of law enforcement, fire & rescue, industrial, security professionals in mind, the light is built to conform to NFPA 1971-8.6 (2013) requirements for fire protection gear and outfitted with a strobe function that can be used to signal your location in an emergency or disorient a threat. All the functions, modes, and intensity levels are controlled using a two-part push-button tailcap switch, with instant access to the strobe from any output level or from off.

Weighing 8 ounces with the included rechargeable and less than seven inches long, the light won't add excessive weight to your duty belt, tool pouch, or gear bag. Made of a lightweight and durable aluminum alloy, the housing is designed to withstand abuse on the job and is treated with an anodized finish that protects it from scratches and corrosion. The housing is also sealed to an IPX7 rating, making it waterproof and submersible to 3.3' for up to 30 minutes so it (and you) can get drenched with a hose and keep working. Each light has an etched serial number to make it easy to identify which one is yours. Nightstick includes a charging cradle that charges the batteries in the light, along with a 110 VAC US house outlet charging cord and a 12 VDC car/vehicle cord for your work truck or cruiser so you can keep your light lit for your whole shift.
