If your lights buzz, or hum, only at the low end of the dimming range, adjust the low-end range of your dimmer until the lights stop buzzing.
Some LED lights buzz or hum more than others. If your lights are buzzing throughout the entire dimming range, use the <a target='_blank' href='https://www.lutron.com/en-US/Pages/LEDCompatibilityTool/Compatibility.a… style='color: #006dcc;'>Lutron LED Finder Tool</a> to find the best-performing bulbs for the dimmer. Alternatively, check with the manufacturer of the LED to see if the light is designed for a specific type of dimmer (low voltage, reverse-phase, etc.). This dimmer only works with 120V lights.
