Ballasts

MH and HPS grow light systems use bulbs with big bases which require a special ballast to start and maintain the correct amount of power. Some ballasts can accommodate both MH and HPS bulbs, the digital ballasts give you additional options for controlling the amount of light given off and electricity used.
