Can you use Surefire tail caps on this light? If so, would I be able to use it in unison with the Unity Tactical TAPS SYNC? Expert Answer

According to the manufacturer: The optional remote switch for the REIN is only compatible with the REIN itself. No reverse compatibility for other light manufactures exists.

Helpful Negative Review Disappointed by Aspeed, Verified Owner, July 25, 2021
I purchased the Rein and Rein Micro to replace a Streamlight Pro-Tac HL-X and an InForce WML-X. Reading about these lights I was really hoping for the best. My SL is 1,000 lumen and 27,000 candela, so I assumed the Rein at 1,400 lumens and 60,000 can...

Sweet light that packs a punch which throws a good distance of light. Can’t go wrong with the Rein! I do prefer the color of the light since it’s around the 5k color mark which offers better visual and light intensity. This is a must buy weapon light...

This light provides good light well beyond 100 yds with clarity using tactical & hunting scopes. Throws light really well through the fog too. I have been very impressed. Battery life is also really good. Haven't run all the way down yet.

Product Info for Cloud Defensive REIN Weapon Light Standard Kit

What a weapon light should be.image

The REIN is the most powerful and most durable complete weapon light system on the market. It features a field serviceable lens, a field-serviceable tail cap and electrically-isolated dual-switching for redundancy. It works with all existing light mounts. And it has the worlds first 3rd generation Light Control System (LCS) including a proprietary remote switch with tail-cap integration, oriented precisely for weapon-mounted use. REIN is redefining what a weapon light should be.

COMPATIBILITY

REIN is fully compatible with any platform that allows for traditional picatinny, M-LOK (trademark) or KeyMod light mounts. The optional remote switch for the REIN is only compatible with the REIN itself. No reverse compatibility for other light manufactures exists.

MATERIALS

Precision machined from Certified 6061-T6 aluminum. Type III Anodized to MIL STD. "Hard coat".

POWER

A state-of-the-art electrical system using the best components that money can buy. That gives us the output, efficiency and run-time that makes REIN the class leader. Uses a single 18650 battery. No CR123 batteries allowed. Use of CR123 batteries VOIDS your warranty. We supply a Samsung 18650 30Q with the REIN. The 30Q battery has more output with shorter run-time of 85-90 minutes. Please note that unlike its peers, REIN will produce useable light for at least 6 straight hours. Accepts ALL protected and unprotected 18650 batteries. Accepts both button-top and flat-top batteries. NOTE: Various battery sizes will require use of the provided Battery Jack feature. Run-time at 100% power is industry-leading.

Features:

  • Modular 3-piece design makes the REIN upgradeable over time.
  • Exceeds well over 60,000 Candela.
  • 1,400 Lumens of output.
  • IPX-8 waterproof rating. Fully submersible to 100 ft for 24 hours. Remote switch included.
  • Run-time standard per ANSI/PLATO-FL1 = 130 minutes. The amount of time until the light reaches 10% of its original output.
  • Proprietary Field-Serviceable Lens System. The end-user can now replace the glass lens themselves. The glass on the REIN is 3mm thick, which is the thickest in the industry. It can take multiple hits from 5.56mm Simuntion rounds.
  • S7 Tool Steel bezel ring. Heat-treated to 53 Rockwell. Your light is now an impact tool.
  • 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 increased reliability substantially.
  • Patented tail-cap cartridge is easily replaceable and allows for multiple configurations without removing the tail of the light.
  • REIN comes standard with a push-button-only configuration. Located in the tail cap, the switch offers both momentary-on and constant-on capability.
  • Patented remote switch (optional). 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.
  • The optional remoted switch is housed in a 3rd Generation Light Control System. Available only for the REIN. It offers unprecedented cable management possibilities never before available even with prior generation LCS units. The remote switch is fully submersible and fully potted.
  • The optional remote switch utilizes a cable exit from the tail cap that is perpendicular to the bore axis. This allows your cable to be protected from potential snags and impact.
  • The optional remote switch wire is over-molded into the tail cap cartridge. And the tail cap body allows for the user to adjust the position of the tail cap based on user requirement or preference.
  • The optional remote switch cable is 5" long.
  • Shockproof. Dustproof.
  • Lifetime Warranty - with only a few exceptions. Remote switches are considered replaceable items not warranty items. Please see warranty info for full details.

Package Contents:

  • 1 REIN
  • 1 Push-Button tail cap
  • 1 Picatinny Rail Mount for the REIN, with all mounting hardware
  • 1 Cloud Defensive labeled Nitecore Charger
