Run time standard per ANSI/PLATO-FL1 = 35 minutes. The ANSI/PLATO-FL1 standard for runtime is: The amount of time until the light reaches 10% of its original output.
Run-time at 100% power is industry leading, as the latest generation of REIN is now even more efficient electrically.

It features a Modular 3 piece design. With a great electrical system and remote switch, REIN has always been upgradeable as subsequent generations are released. As such, all parts of the 1st generation REIN are fully compatible with the 2nd generation REIN.

It has an IPX-8 waterproof rating. Fully submersible to 100 ft for 24 hours. Fully potted remote switch included.

Strongest in class lens. The glass on the REIN is 3mm thick. It can take multiple hits from 5.56mm Simunition rounds, at contact distance.

The Patented Battery Jack feature. This allows you to properly tension the battery inside the system to avoid battery bounce. This lengthens the life of your system and increases reliability substantially.

The Patented remote switch, offers both momentary and constant on functionality. The remote switch is electrically isolated from the push button switch located on the tail cap. If your remote switch suffers catastrophic failure, your REIN still works via the tail cap button.

    Best WML on the market hands-down. Have a full sized (non-micro) Rein 2.0 on a separate AR-15 build. This micro version has been effectively mounted on a 18.5 tactical defense SG.
