Ballasts are essential components for indoor growers, controlling the amount of current that passes through a circuit and helping to ensure optimum plan growth and longevity.

We have chosen a large selection of grow lights for projects of every size and scope. Choose from different wattages and voltages to suit your specific needs as well as dimmable and timer models. Many of the HID ballasts we offer operate both metal halide (MH) and high-pressure sodium (HPS) lamps for greater flexibility—simply switch from one mode to another.
