While all lightbulbs can make that distracting sound, especially when dimmed, it’s more common when using LED lightbulbs. That humming or buzzing sound generally indicates that the lights are using a voltage level that can cause the components in the bulb to vibrate or oscillate. Sometimes it can be caused by using other electrical devices, like your microwave.

But it can also be a sign of an electrical issue. It could be a loose connection, a worn-out fixture, a problem with the wiring, or if it is a dimmer, perhaps it’s not compatible with the type of lights you have installed.

If it’s a loose bulb or fixture, it’s usually an easy fix. But if the bulb is not securely fastened, it can cause the fixture to vibrate, creating a buzzing sound. Tighten the bulb or fixture until it is secure.

In some cases, light buzzing may be due to the type of bulb you are using. Some LED bulbs are designed to buzz, which is usually not noticeable. If you are using an LED bulb and the buzzing is loud or distracting, switching to a different type of bulb would be the easiest solution.

But if the buzzing has worn out the light fixture – which happens over a longer period- the vibration causes the fixture to become loose or damaged. In this case, it is best to replace the fixture altogether.

The biggest issue is if the electrical wiring in your home causes the light to buzz. If the wiring is not installed correctly or has become damaged, it can cause the lights to buzz. This is a serious issue that a licensed electrician should address before it causes a fire.

If the buzzing is accompanied by flickering lights, it may indicate a problem with the electrical supply. Various issues, such as a damaged circuit breaker, a loose connection, or a problem with the electrical supply to your home, can cause this. Again, this is a serious issue that you should get us to investigate.

When a light switch, or any switch for that matter, is buzzing audibly, it can mean that the current between the metal wire contacts inside the switch is arching – jumping rather than flowing through. This jumping can also produce high temperatures, so if the switch is warm, it’s another reason to check your lighting.

So, if you can’t fix the buzzing by tightening the bulb or fixture and replacing the bulb has had no effect, perhaps we can visit to do an electrical audit of your property. The audit reviews the entire property, including the switchboard, because we would much rather stop electrical fires from happening than repair the damage they cause.
