The Lights My Maestro LED+ Dimmer Is Controlling Are Flickering, Buzzing, or Dropping Out

Flickering or Flashing LED Lights

Complete the following steps if your LED lights are flickering:

Check the lights you are dimming

Many LEDs are not dimmable. This includes smart, or connected, bulbs.

Confirm your LED does not have a warning like: "Not for use with dimming devices" or "non-dimmable". If it does, replace it with an LED from the Lutron LED Finder Tool.

If the lights flash or strobe…

Confirm you are not using 2 LED+ dimmers to control the same lights.

Only one Maestro LED+ dimmer can be installed in a lighting circuit. The other location must use a mechanical switch or a Maestro companion dimmer (SKU: MA-R-XX* / MSC-AD-XX*). Visit “Maestro LED Dimmer 3-Way 4-Way Install Tips” for more information.

If the lights flicker or shimmer…

Adjust the low-end range of the dimmer until the lights stop flickering.

If your lights flicker only at the low end of the dimming range, the LED you are using may not dim as low as the dimmer.

Maestro Low-End Trim Adjustment

 

      1. Press and hold the LOWER ROCKER and the on/off TAPSWITCH at the same time (for about 6 seconds), until an indicator light on the dimmer starts to blink. 
      1. Release both buttons and hold the LOWER ROCKER until the lights reach the dimmest level before becoming unstable or turning off.  
      1. Tap the RAISE ROCKER if the lights begin to flicker. Continue tapping RAISE until the lights are on and stable.
      1. Tap the on/off TAPSWITCH once to save and exit the low-end trim setting. The indicator lights stop blinking once the low-end trim setting is exited. 

       

       

      Buzzing or Humming LED Lights

      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 Lutron LED Finder Tool 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. 

       

      LED Lights Turn Off Before the Dimmer Does (Drop Out)

      If your lights drop out at low levels, it typically means you are dimming the LED lower than it is designed to be dimmed.

      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.
