Standard and Digital Ballasts

A ballast is essential to safely run HID lighting. The basic function of the ballast is to regulate the power that your lamp can draw which is why you need to match the wattage of your grow lamp to the wattage of the ballast. Ballasts are available in two types: Standard Ballast which have been around for decades and feature copper wire coils to regulate the wattage.
