Most Helpful Positive Review A Light to Love, a Cable-Management System to Loathe
Cloud Defensive's are the only weapon-lights I put on my long-guns. I own numerous OWLs and a single REIN Micro, the latter of which I operate via a tail-cap switch. In early December 2023, I purchased a REIN 3.0 for my LMT MARS piston rifle. It was my intention to run subject light via the included...

Most Helpful Negative Review It is ok, but there are better features on brands a third of the price.
Bright and feels light yet sturdy. The features are fairly intuitive. It doesn't come with instructions and you will have to find a third party reviewer/unboxing if you have issues because Cloud Defensive's instructions are horrible. The manual on Cloud Defensive's website has no pictures and the...

Great fit and enhances performance.

by Archer, Verified Owner from RI, United States Written on September 12, 2025
A great light that I installed on an LWRC 9mm rifle. I'm going to put it on my new HK SP5 where I think it will be more useful.

Hit the Lights!!!

by Adrian Ortiz, Verified Owner from NE, United States Written on February 27, 2025
Probably too much light for Berreta 1301 but figured I could just throw it on my Fostech AR-15. Love it on Beretta, just need the momentary switch for home defense.

Rein 3.0 full size

by Jay, Verified Owner from TX, United States Written on February 15, 2025
Extremely bright and very good hot spot with exceptional flood view. Easy to install and cable management is great so you don’t have loose cable just hanging. Would definitely buy again.
Pros:
  • Easy Mount
  • Very bright , flood light rechargeable
  • Cable light and laser switches
Cons:
  • Price $$$

Best weapon light I've purchased.

by Claymore Roomba, Verified Owner from FL, United States Written on February 4, 2025
This thing is nice and bright. It's got a ton of throw and plenty of spill so you can really light up what you're focusing on and still have plenty of light for everything around that.

recommend for high end wml

by Shawn Pruitt, from AL, United States Written on January 16, 2025
Read the installation guide provided by scan/card and also you tube. There are differences from this light and others.
I have owned stream light, mod lite, cloud defensive and sure fire.
Cloud is the leader for the beam. It is versatile and support dual fuel.
The sure fire stuff is good too but apples to apples far more expensive. (Great customer support and very rugged and dependable)
Mod lite is good but the company is not. Very poor.
Stream light is great for the money.
The rein (cloud defensive) comes with the switch, battery, mount and also the clicky tail cap. Battery and charger. Everything you need.
It secures the battery in a very unique way (see cd you tube page for details)

Simply put, well thought out and solid.
Priced below the SF and ML but competes or wins vs them.
It does get hot.

So, if you want quality, great beam and a kit that includes everything, CD for the win.
Pros:
  • options, kitted, diverse battery options
Cons:
  • sonewhat complex install
Best Used for:
  • wml
Would recommend: Yes

Best light, wire & switch could be upgraded

by Jake, Verified Owner from UT, United States Written on September 7, 2024
Love the rein 3.0, beats out the surefire and streamlight without a question. Only downside is the wire and switch definitely have room for improvement. Wire out of tail cap can only be adjusted in 90 degree moves.
