Cloud Defensive Rein 3.0 Weapon Light – Micro


Flat Dark Earth (FDE)

Product Description

The Cloud Defensive REIN Micro is a leap forward in both weapon light technology and performance. With a maximum output of 1,000 lumens and 95,000 candela, targets are easily identifiable from close range and out to 200+ yards. In short, this means more light on target, improved situational awareness, and maximum penetration of photonic barriers such as smoke, fog, tint, and other light sources. The compact size of this microlight makes it ideal for short barrel applications where rail space may be limited. The REIN Micro represents the next generation of weapon lights.

Engineered to be shockproof, dustproof, and built to last. We design the REIN to handle the abuse of real-world situations. By utilizing a modular 3-pc design made from Type III Hard Coat anodized 6061-T6 aluminum, we are able to achieve an ultra-robust system that can take the hits while being completely field serviceable. Our strongest-in-class lens is made from 3mm thick glass and is able to withstand multiple shots of 5.56 Simunition rounds at close distance. The REIN is IPX-8 rated for water resistance and can be fully submerged up to 100 feet for 24 hours. Every REIN light is proudly made in the USA and includes a lifetime warranty.

The REIN incorporates a number of innovative design features such as our patented Battery Jack system which secures the battery in place and prevents “battery bounce”. This not only extends the lifespan and dependability of your system but eliminates flicker under recoil found in other lights. This unique feature also allows the use of multiple length and style 18650 and CR123 batteries for whatever the situation may call for.

Our patented REIN switches employ a number of features that set them apart from the competition. For starters, every switch includes integrated cable management for clean, snag-free cable routing. Our switches are also stronger in design and electrically isolated from the push-button tailcap. This means if there’s ever a failure in the remote switch itself, the tailcap can be used as a backup solution. The tail cap cartridge is readily replaceable and facilitates “clocking,” enabling you to reduce cable visibility without detaching the light’s tail. By utilizing our REIN switches we are no longer limited by the power loss found in other tape switch designs.

Dual Fuel compatibility means your REIN Micro can use both 18350 batteries or CR123As. It will also accept all protected and unprotected 18350 batteries, both button-top and flat-top batteries. Fully tested to ANSI/PLATO-FL1 standards
(Note: Expect performance degradation with CR123A batteries.)

Every REIN ships with our standard inline M-LOK mount designed to work on a wide variety of hosts with M-LOK compatible rails. If a different mounting solution is required, all REINs are fully compatible with existing Scout® style mounts.
