Ballasts
Grow light ballasts power high intensity grow bulbs and lamps by regulating the voltage a high-intensity discharge (HID) light or compact fluorescent light receives. Some ballasts power specific bulb types while others are "Switchable" and can power both HPS and MH bulbs. There are three types of ballasts, electronic, digital, and magnetic, typically available in various wattages from 315w to 1000w.
Digital ballasts
Digital ballasts are the latest technology that uses microprocessors to monitor and regulate the voltage and are often dimmable.
Double Ended ballasts
Double-Ended ballasts are specifically made to power double-ended fixtures safely.
Magnetic ballasts
Magnetic ballasts are an older technology and use an electromagnetic system for controlling voltage. They are typically cheaper than the other ballast technologies.
T5 Fluorescent ballasts
Fluorescent ballasts are made specifically to power your fluorescent lights such as the longer T5 bulbs frequently used for propagation of many plants in one small space.
