Program start electronic ballasts accurately heat the lamp cathodes prior to lamp ignition. This type of system allows for frequent switching (up to 50 000 on/off) while providing maximum lamp life and energy efficiency, making them ideal for applications using occupancy sensors.

A ballast is an integral component of most modern lighting systems. It is primarily designed to perform three critical tasks: Deliver the proper voltage to start or ignite the lamp(s), Regulate the electric current flowing through the lamp(s), and Compensate for variations in line voltage. The ballast must correspond exactly to the requirements of the lamp it is designed to operate in order to ensure optimal performance.
