Grow Light Ballasts

Ballasts for lights

Magnetic or digital ballasts are very important for any indoor grow room set up because High Intensity Discharge (HID) grow lamps like HPS and MH can’t run without them. A ballast limits and regulates the power for safe, stable operation. Ballasts have to match the wattage rating of the grow lamp. Eg a 400w lamp has to be powered by a ballast with a 400w rating. A 400w, 600w or 1000w grow lamp must be run from a an equivalent wattage rating ballasts for lights.
