Flickering lights in your home or building can be a little spooky and downright annoying. If you’ve eliminated Casper the Friendly Ghost, then it’s likely one of these common causes of flickering lights.
Dimmer Switches
The use of dimmer switches is the number one reason LED lights flicker. Traditional light bulbs have a glowing filament that slowly cools down when dimmed, while LED lights are either in an on or off state. Older dimmers were not designed to control loads below around 20W. As such, they can sometimes struggle to dim low-power LED lights. Because of the LEDs on or off state, the effect you get is strobing… which we see as flickering.
Make sure your light bulb is compatible with your dimmer. The EarthBulb by EarthTronics, Inc. Dimmer Compatibility List is easily accessible. If this still does not remedy the issue, you can replace your dimmer switch with one that is specifically designed for LED lights. This is typically an easy and low-cost fix, and well worth the benefits of LED lighting.
