Maintenance
The OttLite TrueColor 13W Replacement Tube is designed for long-lasting performance with minimal maintenance.
- Cleaning: If the bulb becomes dusty, gently wipe it with a soft, dry cloth when the lamp is off and cool. Do not use liquid cleaners.
- Disposal: This product contains mercury. Dispose of the bulb according to local regulations for fluorescent lamps. Do not dispose of in general household waste.
Regular replacement is only necessary when the bulb reaches the end of its operational life.
Troubleshooting
If the new bulb does not light up after installation, consider the following:
- Power Connection: Ensure the lamp is properly plugged into a working outlet or that the battery is charged and correctly inserted.
- Bulb Seating: Verify that the bulb is fully and securely seated in the lamp's socket. Gently push it in again to ensure proper contact.
- Lamp Compatibility: Double-check that your lamp is an OttLite 13W Battery Task Lamp and that it requires a 4-pin replacement bulb. This bulb is not universally compatible.
- Bulb Damage: Inspect the new bulb for any visible damage to the glass or pins. If damaged, do not use.
- Lamp Malfunction: If the issue persists after verifying the above, the problem may lie with the lamp itself rather than the bulb. Consult your lamp's manual or OttLite support.
