Cloud Defensive REIN 3.0 Full Size Weapon Light Flat Dark Earth FDE. Over 44percent more than the closest competitor. Nobody else is even close. It means more light on-target than ever before. It means better situational awareness. It means improved survivability. And run-time standards per ANSI/PLATO-FL1 ensure your light performs as long as you need it.Due to enhanced thermal upgrades the REIN 3.0 light head CANNOT be used on any MCH lights. Simply the light head gets too hot which can cause damage to the electrical components. The REIN 3.0 is now DUAL FUEL. CR123 batteries are now allowed. However if you use CR123 expect performance degradation. We supply a branded Samsung 18650 30Q with the REIN 3.0. Please note that unlike its peers REIN 3.0 will produce usable light for multiple hours. Accepts ALL protected and unprotected 18650 batteries. Accepts both button-top and flat-top batteries. Run-time standard per ANSI/PLATO-FL1 = 95 minutes for the full-size REIN 3.0. The ANSI/PLATO-FL1 standard for runtime is: The amount of time until the light reaches 10percent of its original output. As shooters ourselves we know size matters. Particularly when you start working your lights around other systems on the gun such as laser systems and back up sights. With a small 1.3 bezel diameter and lower mounting lug height profile it sits tighter to your gun than ever before. The full-size REIN is now right at home on even the shortest host platforms. Ounces do matter. The Next-Generation REIN numbers speak for themselves. And the new 3.0 generations weight is indistinguishable on the gun from the previous version. REIN 3.0 still ships standard with a M-Lok mount. Cloud Defensive offers a full line-up of Torrent mounts for different mounting needs. REIN 3.0 is fully compatible with existing Scout Light mounts on the market. REIN lights now include a USB-C rechargeable battery with a built-in USB-C port. Use the included white USB-C cable to charge it. To access the battery unscrew the light head - the battery will slide out.
