The bulb ballast is an essential component that controls the flow of current into the fluorescent bulb.
Bulb ballast functionThe bulb ballast is required for the fluorescent tubes to operate correctly. The ballast balances the flow of current and supplies the necessary amount of voltage to actuate the fluorescent lamps. The bulb ballast is necessary because, without the ballast to limit the current, the lamp would increase in current draw and overheat as well as burn out the fluorescent lamp within seconds.
Common issues with a faulty bulb ballastA malfunctioning bulb ballast can lead to an excessive draw of current, overheating, or erratic lighting.
