What is a ballast?

A ballast helps growing bulbs, or high intensity discharge bulbs, such as high pressure sodium and metal halide bulbs, to operate efficiently, smoothly and safely. The ballast helps to provide the proper starting and operating conditions for HID bulbs. This dramatically increases the effectiveness, efficiency and lifespan of these growing bulbs. Another benefit of ballasts is the increased power supply frequency, providing a smoother, more constant light source which is better for growing.
