The UltraGROW UG-RCT/8 Cool Tube is the first choice in indoor grow lighting. Suspended from a hammered aluminum reflector, the fully sealed, tempered glass tube houses any high pressure sodium (HPS) or metal halide lamp up to 1000 watts. A mogul socket is pre-attached to the cool tube and plugs into an external ballast by a 15-foot cord. Aluminum flanges on either end of the tube allow easy connection to a ventilation system. Have a tight grow setup? Hang the fixture horizontally for maximum coverage or vertically to save space. For secure shipment, the Cool Tube comes packaged in a double-walled cardboard box and high-density Styrofoam.
