Dual-Fuel Capability

The REIN 3.0 is designed around a rechargeable 18650 battery, which delivers the light's full performance.

For emergency situations or when rechargeable batteries aren't available, the REIN 3.0 can also operate using two CR123A batteries. While output is reduced, the ability to use either power source provides added flexibility when it matters most.

Built for Performance

Cloud Defensive redesigned the REIN platform from the ground up to maximize both output and usability.

The REIN 3.0 features:

• Smaller bezel diameter than the original REIN
• Lower-profile mounting lug for improved compatibility
• Compact full-size body
• Upgraded internal electrical system
• Increased overall efficiency

The result is a weapon light that offers tremendous beam performance while remaining easy to integrate onto modern carbines.

Our Thoughts

The REIN 3.0 is one of the few weapon lights that truly competes at the very top of the market.

Its 100,000 candela beam provides exceptional throw, allowing positive identification at distances where many weapon lights begin to struggle. At the same time, the 1,250-lumen output provides enough spill to maintain excellent situational awareness indoors and around vehicles.

If your priority is maximum performance, the REIN 3.0 deserves serious consideration alongside lights like the SureFire Turbo and Modlite OKW. It offers outstanding durability, excellent runtime, and one of the most impressive beam patterns available today.

For shooters building a defensive, duty, or night-capable rifle, the REIN 3.0 is one of our highest recommendations.
