The Cloud Defensive Rein 3.0 is a 1250-lumen tactical weapon light designed for shooters who demand serious output and reliability on the line. With 100,000 candela of peak beam intensity, this full-size mounted light delivers over 44% more candlepower than competing options in its class—meaning better target illumination, situational awareness, and the capability to perform when it matters. Built around a modular 3-piece design with a USA-made electrical system, the Rein 3.0 pairs extreme durability with user-friendly features like a fully-potted remote switch and the option to run on either 18650 or CR123A batteries (though 18650 is the preferred fuel for full performance).
This light is built tough for the field and the fight. The lens is 3mm of hardened glass that can withstand multiple hits from 5.56mm Simunition rounds at contact distance. It's fully submersible to 100 feet for 24 hours (IPX-8 rated), shockproof, and dustproof. Cloud Defensive engineered enhanced thermal management into the Rein 3.0, which is why it cannot be used with older MCH light platforms—the head runs too hot for those electrical systems. The modular design means you can upgrade electrical components as new generations release, future-proofing your investment.
The remote switch is electrically isolated from the tail-cap push button, giving you clean momentary and constant-on control with integrated cable management. The switch cable runs 5 inches and can be clocked to minimize cable exposure without disassembling the light. A patented Battery Jack feature keeps tension on your battery to prevent bounce and extend system life. In the box: the Rein 3.0 head, remote switch tail-cap assembly, two side plates with hardware, a Torrent MLOK mounting solution, a charger, and a branded 18650 battery—everything you need to mount and run immediately.
| Output | 1250 lumens (with 18650) |

| Runtime (ANSI/PLATO-FL1) | 65 minutes (with 18650) |
| Length | 6.17 inches |
| Bezel Diameter | 1.3 inches |
| Weight | 6.91 oz (with remote switch and battery) |
| Battery Type | 18650 (primary) or CR123A (secondary) |

| Lens | 3mm hardened glass |
| Standard Mount | Torrent MLOK Inline |
| Color | Flat Dark Earth aluminum |
| Warranty | Lifetime (with limited exceptions) |
No. The Rein 3.0 head cannot be used on older MCH lights due to enhanced thermal upgrades in the Rein 3.0 design. The increased heat output can damage the electrical components in MCH platforms. However, the Rein 3.0 is fully compatible with existing Scout Light mounts on the market.
The Rein 3.0 ships with a branded Samsung 18650 30Q battery and a charger. You can use any protected or unprotected 18650 battery (button-top or flat-top), or CR123A batteries as an alternative. Keep in mind that CR123A use will result in performance degradation compared to 18650 operation. With an 18650, you'll get the full 1250 lumens and 65 minutes of runtime (per ANSI/PLATO-FL1 standard, measured to 10% original output).
The Rein 3.0 comes standard with a Torrent MLOK Inline mount and all necessary hardware. It's also fully compatible with existing Scout Light mounts. Cloud Defensive offers a full line of Torrent mounts for different mounting configurations if you need alternatives.
Yes. The remote switch is fully potted (sealed) and electrically isolated from the tail-cap push button. The light itself carries an IPX-8 waterproof rating and is fully submersible to 100 feet for 24 hours.
