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. 
<h4 style='box-sizing: border-box;padding: 0px;font-size: 12pt;display: block;margin-inline: 0px;line-height: 1.2;margin-block: 1.33em;color: rgb(24, 24, 24);white-space: normal;margin: 2pt 0in 0in;background-color: white;font-family: 'Times New Roman', serif;'>LED Lights Turn Off Before the Dimmer Does (Drop Out)</h4>

<p style='box-sizing: border-box;margin: 0in 0in 8pt;padding: 0px;color: rgb(24, 24, 24);white-space: normal;background-color: rgb(255, 255, 255);line-height: 16.96px;font-size: 12pt;font-family: 'Times New Roman', serif;'>Use the low-end trim setting to raise the low-end range of the dimmer. This helps create a smooth dimming curve, specific to the range of the LED being used. Watch the video above to learn how to adjust your Lutron dimmer's low-end trim.
