The Larson 4000 skid-mounted, fold-over light mast features four 1000-W metal halide lamps on a telescoping boom. The boom can extend to a full height of 30 ft with 360° of rotation. The four lamps are able to produce 440,000 lumens of illumination and the lamps can be switched on or off individually via the built-in control box. A hand-operated winch is a standard feature, with an electric-powered winch available as an option. The light mast is skid-mounted for easy transport around the job site.
