- Replacement: Replace the tube when it reaches its end of life, indicated by flickering, reduced brightness, or failure to illuminate. Always disconnect power before replacing the tube.
- Disposal: Fluorescent tubes contain small amounts of mercury and should be disposed of according to local environmental regulations. Do not dispose of with regular household waste.
6. Troubleshooting
If you encounter issues with your fluorescent tube, refer to the following common troubleshooting steps:
- Tube Does Not Light Up:
- Ensure the power supply to the fixture is active.
- Check that the tube is correctly and firmly seated in the 2G11 socket.
- Verify that the ballast (if present) is functioning correctly and is compatible with the tube.
- If replacing an old tube, ensure the new tube is not faulty.
- Tube Flickers:
- Flickering can indicate an aging tube nearing its end of life. Consider replacement.
- A faulty or incompatible ballast can also cause flickering.
- Ensure stable power supply to the fixture.
- Reduced Brightness:
- The tube may be nearing its average lifespan.
- Dust or dirt on the tube surface can reduce light output. Clean as per maintenance instructions.
If problems persist after following these steps, contact a qualified electrician or OSRAM customer support.
