7. Troubleshooting
If your fluorescent tube is not functioning as expected, consider the following common issues and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Bulb does not light up. | No power to the fixture, loose connection, faulty bulb, or faulty ballast. | Check circuit breaker. Ensure bulb is securely seated. Try a known working bulb. If still no light, the ballast may need replacement by a qualified electrician. |
| Bulb flickers or hums. | Aging bulb, incorrect ballast, or cold temperature. | Replace the bulb if it's old. Ensure the ballast is compatible with T5 fluorescent tubes. Fluorescent bulbs may flicker more in cold environments. |
| Dim light output. | Dust accumulation on bulb, aging bulb, or incorrect voltage. | Clean the bulb. Replace the bulb if it's nearing end-of-life. Verify the fixture's voltage matches the bulb's requirements (230 Volts). |
If troubleshooting steps do not resolve the issue, consult a qualified electrician.
