What is a ballast?
A lamp needs energy to light up, but the energy it draws is generally more than it really needs. To get the lamp closer to the necessary amount of energy rather than the excess it takes in, a ballast is connected to the lamp. Each ballast type is different but works by adding an electrical load to the lamp and then including a negative resistance and resistors to balance the energy. Inclusion of a ballast will increase lamp life and lower operating costs.
