Troubleshooting

Bulb does not light up

Check that the bulb is correctly seated in the 2G11 socket. Verify that the electronic control gear (ECG) is properly connected and functioning. Ensure the power supply is active.

Flickering light

This may indicate an issue with the ECG or a loose bulb connection. Check the connections to the ECG and ensure the bulb is firmly in its socket. If the problem persists, the ECG may need replacement.

Dim or poor light output

Ensure the correct wattage bulb is used with the ECG. Check the lumen maintenance ratings; if the bulb is near the end of its lifespan, replacement may be needed. For dimmable fixtures, check dimmer settings and compatibility.

Bulb lifespan is shorter than expected

Ensure the bulb is operated with a compatible and correctly rated electronic control gear. Frequent on/off switching can reduce lifespan; consider using it in areas with fewer switching cycles if possible.
