Nextorch WL13 Weapon Light 1300-Lumen Blazing Tactical Brightness Nextorch tactical tools represent some of the best of their inventory, and the newest addition to the WL (Weapon Light) series of products leads by example. The Nextorch WL13 Weapon Light emits 1,300 lumens of ultra-bright white light that will drive away the darkness on your next sortie. Ambidextrous rotary switches offer custom momentary-on or constant-on illumination at a moment's notice, making it a great choice for left-handed field operators as well as righties. The nimble size and compatibility with Picatinny and Glock rail systems make the WL13 highly versatile and ideal for use on small arms. With its whisper weight design, the weapon light empowers you to maneuver your weapon easily to buy those life-saving seconds in identifying and acquiring targets. Straightforward Rail Mounting — Optional Battery Sizes The WL13 deploys two types of batteries to best fit your needs. Use a pair of CR123A units to unlock peak overall performance and impressive 3+ hour runtimes. Alternatively, dual 16340 offer reliable perofrmance and recharge capabilities making them a perfect back-up power supply. Exceedingly simple installment is made possible by a mounting system that requires minimal effort to operate. The Rail-Adjustment Bolt slides a moveable rail into place while the stationary rail is held against the weapon. This quick installment and the WL13's easy operation make this a must for use in the field.
