The Cloud Defensive REIN 3.0 Weapon Light is a full-size rifle-mounted LED weapon light producing 1250 lumens output and 100,000 candela peak beam intensity — one of the highest-throw rifle lights available, with a tightly focused hotspot and controlled spill.
It is dual fuel, running the included 18650 rechargeable lithium cell or CR123A primaries with no change in output, and the remote pressure switch is integrated rather than bolted on, which keeps the cable managed. The 6061-T6 aluminium body is Type III hardcoat anodised and rated IPX8, and a Picatinny mount is included.
How It Compares
Want the same output in a shorter body? The REIN 3.0 Micro rifle light runs an 18350 cell at 95,000 candela. For a pistol-mounted light with rifle-grade candela, see the EPL Duty pistol light.

Frequently Asked Questions
Which rails does the Cloud Defensive REIN 3.0 fit?
The Cloud Defensive REIN 3.0 ships with a Picatinny mount, so it fits any host carrying a standard Picatinny rail section.
How far does the Cloud Defensive REIN 3.0 throw?
The Cloud Defensive REIN 3.0 produces 100,000 candela peak beam intensity, which puts it among the highest-throw rifle lights made. Candela measures how tightly the beam is focused and is what determines throw, while the 1250 lumens figure is total output.
What does dual fuel mean on the Cloud Defensive REIN 3.0?
Dual fuel means the Cloud Defensive REIN 3.0 runs either the included 18650 rechargeable lithium cell or CR123A lithium primaries, with no change in output between them.
How is the Cloud Defensive REIN 3.0 switched on?
The Cloud Defensive REIN 3.0 uses an integrated remote pressure switch, so the pad and cable are part of the light rather than a separate accessory to source.
Is the Cloud Defensive REIN 3.0 waterproof?
The Cloud Defensive REIN 3.0 is rated IPX8, the highest ingress rating in common use for torches and weapon lights.
REIN 3.0 or REIN 3.0 Micro — which should I choose?
The full-size Cloud Defensive REIN 3.0 gives the longest throw at 100,000 candela; the REIN 3.0 Micro is a shorter, lighter body at 95,000 candela on an 18350 cell.
