7. Troubleshooting
If you encounter issues with your GE LED T8 Tube Light Bulbs, refer to the following common troubleshooting steps:
- Bulb Does Not Light Up:
- Ensure the power to the fixture is on at both the wall switch and the circuit breaker.
- Verify the LED tube is correctly seated in the fixture sockets. Gently push and rotate to ensure a secure connection.
- Check if the existing electronic ballast is compatible with LED T8 tubes. Some older or incompatible ballasts may not work.
- Test the bulb in another known working fixture, if available, to determine if the issue is with the bulb or the fixture/ballast.
- Bulb Flickers:
- Flickering can indicate ballast incompatibility. Ensure your fixture's electronic ballast is compatible with LED T8 tubes.
- Ensure the bulb is securely installed and making good contact with the sockets.
- Reduced Brightness or Uneven Light:
- Confirm the power supply voltage is within the specified range (100-120 Volts).
- Ensure the bulb is clean and free from obstructions.
If these steps do not resolve the issue, please contact GE customer support for further assistance.
