We have a wide variety of Plant Lighting H.I.D. Remote Assembled Ballasts from Sunlight Supply. The ballast is the power source of a lighting system. A complete grow light system needs a ballast, reflector/socket assembly, and lamp (bulb). There are four main types of H.I.D. ballasts:
Electronic Ballasts - The new electronic ballasts operate MH and HPS lamps (one at a time) with a number of other advantages.
Metal Halide (MH) Ballasts - Magnetic ballasts that operate only MH lamps (bulbs) - blue light best for seedlings and vegetative (green-leafy) growth stage. HPS light can only be used with MH ballasts if a special HPS Conversion Lamp is purchased.
High Pressure Sodium (HPS) Ballasts - Magnetic ballasts that operate only HPS lamps - red light for fruiting/flowering stage. MH light can only be used with HPS ballasts if a special MH Conversion Lamp is purchased.
Switchable Ballasts - Magnetic ballasts that operate MH and HPS lamps (one at a time).
The Wattage depends on how much grow space you have and what you are growing. For more help choosing the right ballast for you, check out our Lighting FAQs page or give us a call.
