A lighting ballast is an interface device that uses analog or solid-state circuitry to get the right amount of electricity to your bulbs. If you’re planning on using a high intensity grow light, you need a ballast. The key to getting the best light output and long lamp life is to have a ballast that meets the requirements of the lamp. A ballast regulates how much current goes to the lamp and gives a voltage jump to start the lamp in a fluorescent system. Without a ballast, the lamp would overheat and burn out. Many digital ballasts are dual voltage, which means they can run 120 volt or 240 volt and have a range of wattages from 250 watts all the way up to 1,500 watts. You can run either metal halide (MH) or high pressure sodium (HPS) bulbs without having to flip a switch. If you want to be assured that you are using an efficient, effective, and safe product or if privacy is a concern, get a high-quality ballast from Hydrobuilder.
