Maintenance
Minimal maintenance is required for your fluorescent bulb.
- Cleaning: Periodically, with the power off and the bulb cool, gently wipe the bulb with a soft, dry cloth to remove dust and debris. Do not use liquid cleaners directly on the bulb.
- Replacement: Replace the bulb when it reaches the end of its rated life (approximately 7,500 hours) or if it begins to flicker excessively, dims significantly, or fails to light. Refer to the installation section for replacement procedures.
Troubleshooting

| Problem | Possible Cause | Solution |
|---|---|---|
| Bulb does not light up. | No power to the fixture. Bulb not properly seated. Faulty bulb. Faulty ballast or fixture. |
Check circuit breaker/fuse. Ensure bulb pins are fully inserted and twisted securely. Try a new, known-good bulb. Consult a qualified electrician for fixture/ballast issues. |
| Bulb flickers or hums. | Bulb nearing end of life. Incorrect ballast. Loose connection. Cold ambient temperature. |
Replace the bulb. Ensure ballast is compatible with T-5 bulbs. Turn off power and re-seat the bulb. Fluorescent bulbs may flicker more in cold conditions until warmed up. |
