PERFORMANCE: Finally. The REIN Legacy Body gives you the ability the run other tail caps and other remote switches on your REIN. Using a Unity Tactical™ or Surefire™ branded remote switch with a Surefire™ tail cap assembly, with a REIN 3.0 light head and a Cloud Defensive branded 18650 battery, you can expect 90,000 candela from your light. That reflects only a 10% drop from the 100,000 candela the proprietary Cloud Defensive REIN remote switching yields. By giving up that 10%, however (barely noticeable to the eyes), you gain all the cross-compatibility that many of you want and need. And your REIN system is still more powerful than any other option on the market when you factor in the combined lumen and candela capability. An important word on that 10% loss: It’s approximately a 10% reduction in output and subsequent candela. Cloud Defensive use the word “approximate” because that number will technically differ from tail cap to tail cap based on which one you choose. It will also differ from remote switch to remote switch, based on which one you choose. Cloud Defensive strongly encourage everybody not to get wrapped up in the nuance of this reality. Instead, focus on the fact you are getting 90% of what the REIN is capable of, and you are getting that through tail caps and remote switches that you already have or want. You generally need dedicated equipment to see a difference in performance from 90% to 100%. And even at 90%, in the case of the REIN 3.0, the Legacy build gives you more capability than any other brand on the market when you factor in the combination of both lumens and candela. Run-time standards per ANSI/PLATO-FL1 ensure your light performs as long as you need it. POWER: The fuel source that your light head was designed for dictates the fuel source for the REIN Legacy body. All REIN lights are optimized for use with Cloud Defensive-branded Samsung™ flat-top 30Q 18650 batteries or 18350 batteries in the case of the REIN Micro. If you have a Dual-Fuel light head, you can still use your CR123A batteries as a secondary power source. Cloud Defensive recommend only using flat-top batteries. Most button-top batteries are not compatible with the REIN Legacy Body. DIMENSIONS: The smaller diameter of the Surefire™ tail cap will yield a smaller tail-cap profile which will reduce the overall profile of your REIN light. When coupled with the Unity Tactical™ or Surefire™ switches, please be aware the overall length of your system will be a little longer than Cloud Defensive’s remote switch offering. Cloud Defensive know size matters. Particularly when you start working your lights around other systems on the gun, such as laser systems and backup sights. With a small 1.3” bezel diameter and lower mounting lug height profile, it sits tighter to your gun than ever before. The full-size REIN is now right at home on even the shortest host platforms. REMOTE SWITCHES: The REIN Legacy body was created for the purpose of allowing you to use other remote switches and tail cap assemblies with your REIN 3.0 weapon light. As such, it is widely and fully compatible with all the Surefire™ and Unity Tactical™ remote switching options commonly used with Scout™ – pattern lighting systems. A non-exhaustive list of some of the switches Cloud Defensive are compatible with: Surefire™ ST-07 Surefire™ SR-07 Surefire™ SR-07-D-IT Unity Tactical™ Hot Button Unity Tactical™ TAPS Unity Tactical™ AXON Modlite™ Modbutton In short: If it plugs into a Surefire™ tail cap, it works with the Legacy Body and any Cloud Defensive REIN light head you put on. IMPORTANT WARRANTY AND FUNCTIONALITY INFORMATION: By combining parts from multiple manufacturers, the nature of the system changes. Remember, these are electrical components that Cloud Defensive are trying to play nice with, and that adds complexity. Typically, electrical failures occur in the tail caps and the remote switches. This has been well established across the weapon light community. Regardless of the failure point, Cloud Defensive stands resolute behind its Lifetime Warranty. However, in the case of a REIN 3.0 being controlled by other companies’ components, please consider a couple of realities: WARRANTY: Cloud Defensive can only warranty Cloud Defensive parts. Cloud Defensive do not warranty other manufacturers’ components. Failure of any non-Cloud Defensive component must be handled by the respective manufacturer. Adding a layer of complexity to this is the reality that when a part fails in the field, the light very well may fail completely, but you are not likely to know why. Meaning you would not be able to quickly discern a dead tail cap from a dead light head, each of which was made by a different manufacturer. If that happens, you need to contact Cloud Defensive’s Customer Service department. They will then walk you through a process to determine what failed. In this scenario, it is not likely to be a Cloud Defensive part. If it is, Cloud Defensive will replace it immediately per warranty. If it’s a part Cloud Defensive did not make (i.e. tail cap or remote switch), then you will need to speak with the appropriate company, and you’ll be subject to their warranty support and process. The REIN Legacy Body does NOT offer a Battery Jack feature. That means there is no adjustability in the system for various battery lengths. The REIN Legacy Body will run best on flat-top 18650 cells or two CR123 batteries. Button-top cells do not perform as well and that is why Cloud Defensive do not use them. Cloud Defensive is in the business of giving you the maximum performance possible. So, the Legacy Body has been optimized for the batteries that give you maximum performance. Historically, REIN lights are IPX-8 rated to 100ft for 24hrs. With a different Tail Cap and Remote assembly, expect that rating to parallel the respective rating of the Surefire ™ and/or Unity Tactical ™ components. And yes. Made in the USA. Output Specs & New Features (with REIN 3.0 head) 90,000 Candela peak beam intensity (With 18650) 1100 Lumens output (With 18650) 65 minutes run-time (With 18650) Dual-Fuel capability. REIN 3.0 runs on 18650 and now can also run on two CR123 batteries. 18650 rechargeable battery provides the best output, by far. However, you can now use 2 CR123A batteries if needed. You will see reduced output with CR123A batteries (50,000 Candela, 400 Lumens and 60 minutes runtime, respectively). 3” Bezel diameter – smaller than the original REIN in diameter. Lower mounting lug profile keeps the REIN 3.0 closer to your rail than ever before. Included In the Box: REIN Legacy Light Body 18650 Battery Spare o-ring (for REIN 2.0 light heads)
