Dual Arc Tube Lamp 1000W delivers powerful, full-spectrum light by combining both high-pressure sodium (HPS) and metal halide (MH) technologies in a single bulb. Designed for growers who want the best of both worlds, this lamp boosts vigorous vegetative growth and explosive flowering—all from one light source. Ideal for high-yield environments, it fits standard 1000W ballasts and maximizes canopy penetration with enhanced PAR output.
