The Cloud Defensive REIN 3.0 is a full-size, high-candela rifle light built for maximum beam intensity and long-range performance. It produces 1250 lumens and a huge 100,000 candela — a tightly focused hotspot with controlled spill that punches through distance and photonic barriers (glass, smoke, ambient light) for superior target identification.
The dual-fuel system runs the included rechargeable 18650 or CR123A primaries with no change in output, and an integrated remote pressure switch keeps activation consistent with tidy cable management. The 6061-T6 aluminium body is Type III hardcoat anodised and IPX8-rated.
