The iProtec O2 Beam RC Green is a rechargeable long-range light for rifles and shotguns, made for night hunting. It uses iProtec's O2 technology with a green filter to produce a green beam, which the eye picks up quickly in low light and which many game animals are less sensitive to than white light. Output is 400 lumens on high (about 2 hours, 451 m beam), 40 lumens on low (about 6 hours, 143 m) and a 400-lumen strobe. The body is aircraft-grade aluminium, water and impact resistant, about 159 mm long with a 54 mm head. Power comes from an 18650 lithium-ion rechargeable battery, and a pressure pad switch lets you operate it from the fore-end. The mount fits barrels and scopes from 20 mm to 32.5 mm, tightens and locks without tools, and has a rail for extra accessories. Listed as end of line by the distributor.
