Why do my fluorescent lights keep burning out?
Issues with the Ballast The ballast takes in electricity and then regulates current throughout the bulbs.

When the light switch is flipped on, the starter sends out a shot of electricity to the gas inside the fluorescent tube. That gas is then ionized and can conduct the electricity necessary to run the bulb. But there’s a slight delay in this process, so the bulbs flicker a bit before they turn on completely.
Is it the starter or the ballast?
In older fluorescent fixtures, the ballast, or choke, is a transformer that limits the current flowing into the tube, while the starter provides the high voltage needed to excite the tube when it is turned on.
