Troubleshooting

Bulb does not turn on

Ensure the bulb is screwed in correctly and firmly. Check that the light fixture is receiving power by testing with another known working bulb. Verify the power switch is in the 'on' position.

Flickering light

This can sometimes occur if the bulb is not seated properly in the socket or if there is an issue with the light fixture's wiring. Try re-seating the bulb. If flickering persists, consult an electrician.

Reduced brightness

Ensure the bulb is the correct wattage replacement and is compatible with the fixture. Check that the fixture is clean and free from obstructions that might dim the light.

Setup, Compatibility & Care

Setup: Ensure the light fixture is switched off at the mains before attempting to replace a bulb. Screw the UniBulb LED GLS E27 bulb firmly into a standard E27 (ES) lamp holder. Once installed, switch the fixture back on.

Compatibility: These bulbs are designed for standard E27 (ES) screw lamp holders. They are compatible with most fixtures designed for GLS-style bulbs.
