Ballasts

Grow light ballasts convert electricity from standard outlets into the voltage needed to start and operate high intensity plant lighting. Our extensive selection allows you to find the remote ballast that best fits your needs and budget, whether high pressure sodium (HPS), metal halide (MH), convertible or digital… and in the wattage you desire. Just starting out or want to make sure you’ve made the perfect lamp-ballast match? Give us a call.
