A ballast is an electronic or electromechanical device that regulates the flow of electricity to the UV lamp. It ensures proper operation and extends lifespan by preventing electrical surges and overloads. 

The ballast converts the input voltage required to spark the UV lamp. Once the UV lamp is sparked and the arc is achieved, the ballast limits the voltage to a lower working voltage to keep the lamp illuminated while regulating the lamp’s power draw.
