Cloud Defensive REIN 3.0 Light Kit

The Cloud Defensive REIN 3.0 Light Kit was designed to be the most powerful and most configurable weapons light ever made. It ships with a Picatinny Rail mount, but Cloud Defensive offers a full line of Torrent mounts for different mounting needs. With an upgraded electrical system, it brings you more capability. The light features 1250 lumens output, 100,000 candela peak beam intensity, and 95 minutes of run time. It has dual fuel capability, which means it can run on 18650 or on two CR123 batteries. The light is IPX-8 waterproof, making it fully submersible to 100 feet for 24 hours, and shockproof and dustproof. Made in the USA and features a lifetime warranty.

Cloud Defensive REIN 3.0 Light Kit Features


Still ships standard with a Picatinny Rail 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.


Ounces do matter. The Next Generation REIN numbers speak for themselves. And the new 3.0 generation’s weight is indistinguishable on the gun from the previous version. Weight with remote switch and battery: 6.91 oz.

Remote Switch

The current switch from the REIN 2.0 has proven to be so good both electrically and in durability, it was an easy choice to keep it in place for the REIN 3.0. With easy activation, both momentary and constant on capability, integrated cable control, the REIN remote switch is the gold standard.


As users, Cloud Defensive knows 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 platform. REIN Length: 6.17?.


USA made, state of the art electrical system using the best components that money can buy. That gives the output, efficiency and run time that makes REIN 3.0 the class leader.

Uses a single 18650 battery.

The REIN 3.0 is Dual Fuel. CR123 batteries are now allowed. However, if you use CR123, expect performance degradation. Cloud Defensive provides 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/PLATE-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 10% of its original output.


An average of 100,000 candela in the full size configuration represents a seismic leap in capability for the user. Over 44% more than the closest competitor. Nobody else is even close. It means more light on target than ever before, better situational awareness, and improved survivability and run time standards per ANSI/PLATO-F1 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.
