We have a wide variety of Plant Lighting H.I.D. Remote Assembled Ballasts. The ballast is the power source of a grow light 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. There are also MH bulbs that have higher levels of red for use in the fruiting/flowering stage.  HPS bulbs can only be used with MH ballasts if a special HPS Conversion bulb 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).
