Understanding the Causes of Buzzing and Humming Noises in Light Fixtures
Electric current and LED operation can contribute to buzzing and humming noises in light fixtures, as can common causes such as incompatibility between LED lights and dimmer switches, dying light bulbs, faulty fluorescent tubes, and malfunctioning ballasts.
Electric current and LED operation
LED lights work with electric current. They send this current in a single way or path, much like water flowing down a river. But sometimes, there can be issues. LED lights create light when the current flows through them.
This is different from other types of bulbs that turn hot and then glow to make light. Sometimes an LED light might buzz if there’s too much current passing through it. It can also happen if the power supply changes quickly or often.
So, careful control of the electric conditions is key for stoping buzzing sounds in LED lights.
Common causes of buzzing and humming noises
Buzzing and humming noises in light fixtures can be caused by a few different things. Here are some common causes:
