An average of 95,000 Candela in the Micro-size configuration represents a seismic leap in capability for the user. It means more light on-target, better situational awareness, and improved survivability. Run-time standards per ANSI/PLATO-FL1 ensure your light performs as long as you need it. Due to enhanced thermal upgrades, the REIN micro light head CANNOT be used on any MCH lights. Simply, the light head gets too hot which can cause damage to the electrical components.

  • Run-time standard per ANSI/PLATO-FL1 = 40 minutes for the micro REIN. The ANSI/PLATO-FL1 standard for runtime is: The amount of time until the light reaches 10% of its original output.


  • The micro REIN uses a USA-made, state-of-the-art electrical system. That gives us the output, efficiency, and run-time.
  • Uses a single 18350 battery.
  • The REIN micro is now DUAL FUEL. A CR123A battery is now allowed. However, if you use CR123A, expect performance degradation. We supply a branded 18350 battery with the REIN micro. Please note, REIN micro will produce usable light for multiple hours.
  • Accepts ALL protected and unprotected 18350 batteries. Accepts both button-top and flat-top batteries. 


  • 1.3” bezel diameter
  • Lower mounting lug height profile
  • REIN Length: 4.88″


  • REIN micro weight with Remote Switch and Battery: 5.41 oz


REIN micro ships standard with a Torrent MLOK Inline. Cloud Defensive offers a full line-up of Torrent mounts for different mounting needs. REIN micro is fully compatible with existing Scout Light® mounts on the market.


The REIN switch has proven to be good both electrically and in durability. The remote switch is electrically isolated from the push-button switch located on the tail cap. Tail-cap cartridge is easily replaceable and allows for “clocking” so you can minimize cable exposure, without removing the tail of the light.

  • Momentary and constant-on features.
  • Integrated cable control.
  • Electrically isolated


  • Modular 3-piece design. With a modular electrical system and remote switch, REIN micro is upgradeable as subsequent generations are released.
  • IPX-8 waterproof rating. Fully submersible to 100 feet 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.
  • 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 exposed cable for the remote switch is 5” long.
  • Shockproof. Dustproof. The most durable weapon light made. Period.
