Why are my LED lights flickering?

LED bulbs can flicker or buzz when the current isn’t constant. There are several troubleshooting steps you can take if you are experiencing a flickering light:

1. Check the bulb - Sometimes a poor contact between the light base and the fixture can cause issues with the flow of an electric current. Make sure your bulb is firmly tightened in the light socket. Also, ensure the screw base of your light fixture is not corroded.

2. Check the fixture - There may be a loose wire or connection in your light fixture. Select another bulb of the same type (one that is working properly elsewhere), then test it in the same socket/fixture. If that second bulb works, then move on to step 3. If not, examine the wire connection between the bulb and circuit. If wires are loose or about to disconnect/break this can cause a flickering.

3. Check dimmer compatibility - Buzzing or flickering may indicate that the dimmer is not compatible with the light bulb. We highly recommend using an ELV (electronic low voltage) LED dimmer from our list of compatible dimmers in our Manuals & Documentation page.

4. For smart bulbs - If you are using a dimmer with a smart bulb and are experiencing buzzing or flickering, please plug that light fixture into a circuit without a dimmer. Sunco LED Smart Bulbs do not need a dimmer. You can control the dimming via your smart phone or tablet with and app over WiFi.

5. For appliances - Make sure that any fans or other high power drawing appliances are not connected to the same circuit as your LED light bulbs.
