The Nextorch WL50IR is a rail-mounted dual-light weapon light with both a white Cree LED and an infrared LED. Rotating the patented head switches between white light and IR, for use with night-vision equipment. On white it gives up to 860 lumens on CR123A batteries (750 lumens on an 18650) with high, medium and low levels and a throw of up to about 290 metres. It runs on two CR123A batteries or one 18650 rechargeable. The tactical remote switch offers constant-on and momentary operation, and it mounts on standard Picatinny rails without tools. The body is aerospace-grade aluminium with Type III hard anodising, IPX7 waterproof to 1 metre and rated for 500G shock. It measures 159 x 42 x 40 mm and weighs 195 g without batteries.
