The 500 Watt Super Spectrum assembled ballast from Sunlight Supply combines Metal Halide and High Pressure Sodium in one ballast for true full spectrum lighting. To truly get full spectrum light, the blue spectrum of metal halide must be blended with the red spectrum of high pressure sodium. When this is done, the spectrum of the fixture is unparalleled by any single lamp source. This Super Spectrum ballast runs both Metal Halide (250W) and HPS bulbs (250W) at the same time to achieve true full spectrum lighting. Includes dual spectrum remote ballast, two lamp cords and socket assemblies and power cord. Add optional single or double integrated intermatic timer to this full spectrum ballast. Purchase Super Spectrum reflector and 250W HPS & 250W Metal Halide bulbs separately. Save when you buy a complete Dual Super Spectrum grow light system that includes reflector, HPS & Metal Halide bulbs and dual ballast.
