Legacy P/N: 1016885
It provides the high voltage required to start the lamps and then limits the current to a safe value.
There are two main types of fluorescent ballasts: magnetic and electronic. Magnetic ballasts are older and less efficient than electronic ballasts. They are also larger and heavier. Electronic ballasts are smaller, lighter, and more efficient. They also provide a more consistent light output than magnetic ballasts.
