Overview

The Cloud Defensive REIN 3.0 delivers crushing performance with 1,250 lumens and 100,000 candela—over 44% more candela than the closest competitor. This third-generation weapon light represents a seismic leap in capability, allowing clear positive identification (PID) of targets from close range out to 300+ yards. The REIN 3.0 cuts through fog, rain, and photonic barriers with authority, providing exceptional performance in adverse conditions where lesser lights fail.

Unlike competitors that drop to 10% output quickly, the REIN 3.0 produces usable illumination for multiple hours beyond the ANSI/PLATO-FL1 standard runtime of 95 minutes. The dual-fuel system runs on 18650 rechargeable batteries for maximum output or accepts two CR123A batteries for emergency backup. Cloud Defensive's patented Battery Jack feature properly tensions the battery to eliminate bounce, increasing reliability and extending system lifespan.

Built from certified 6061-T6 aluminum with a smaller bezel than the original REIN (1.3 inches), the 3.0 measures 6.17 inches long and weighs just 6.91 ounces. The IPX-8 waterproof rating ensures full submersion to 100 feet for 24 hours, while the 3mm thick glass lens withstands multiple impacts from 5.56mm Simunition rounds at contact distance. The patented remote switch offers electrical isolation—if the switch fails catastrophically, the tail cap button still functions.
