- 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.
