Fluorescent lights on the whole have a long life span. The light consist of 3 major components which makes the light work namely, the Fluorescent tube, The Ballast and The starter. If a fluorescent light starts giving trouble, these 3 components are the main culprits. So to troubleshoot faulty fluorescent light, start with these 3 components.
Ways To Troubleshoot Faulty Fluorescent Light
Is the florescent tube blinking or flickering?
If it is, there is a 90% chance that you have a faulty florescent tube. Just twist out the tube and replace it with a new one.
Both ends of the tube are glowing red.
Then the fault is with the starter. The starter acts like a booster to kick start the light. It will weaken over a certain period. Change the starter.
Nothing happens when I switch the light on.
This can be a little bit tricky. There are a few possibilities.
- The switch is faulty
- The wire connections are have loosen
- The ballast have burnt itself out
Whatever it is, if the fluorescent light is dead as a door-nail, I would suggest you call in an electrician to do the troubleshooting. Bear in mind that troubleshooting might cost you more than replacing the light entirely as it is more time consuming.
