Why Is Your Lutron Caseta Light Blinking?

There are 3 reasons why your Lutron Caseta Light could be blinking. The reasons for solutions are as follows:

Compatibility Issues:

Lutron Caseta lights are LED light bulbs. So, Lutron lights flicker when off because they’re more sensitive to electric fluctuations. 

A filament is not present in an LED bulb. It features an electronic driver instead. When current flows to that bulb, the current will apply to those individual LEDs.Thus, the bulb lights up. 

LEDs are more directly impacted by fluctuations. This impact also depends on the LED bulb’s design.


  1. Make sure your dimmer and LED bulbs are compatible: For LED lights, there are no manufacturing standards. They could vary from one bulb to the next.

Even though some lights claim to be dimmable, some will dim more gradually and further than others.

Some bulbs work best with a particular style of dimmer. Therefore, you have to be sure that your dimmer and LED bulbs are compatible.

  1. Adjust your dimmer’s low end: At lower light intensities, flicker is frequently more noticeable. The following adjustments can be made to your dimmer’s lower end to lessen low-end flicker.

Also, your Alexa might show compatibility issues with your devices.  

Not Using A Dimmer with A Neutral Wire:

Another possible reason could be the PD-6WCL dimmer. It can cause your Lutron Caseta with flashing issues.  You must switch to a different dimmer if you are using a new bulb, adjust the dimmer’s lower end, and use a neutral connection.

  2. A status light will start to flash when you have held the top and bottom buttons down for six seconds.
  3. For the forward phase (MLV), tap the top button. The top status light will start to flash.
  4. Tap the bottom button to access the reverse phase (ELV). The status light at the bottom will start to flash.
  5. Hold the bottom button down until the status light stops flashing to finish the setting.
  6. Don’t delay finishing the setting. The power will shut off and the setting won’t be saved if the dimmer times out after one minute of inactivity. You’ve to repeat the process.

Low-End And High-End Trim:

Another reason could be when low-end and high-end trims of the light are not correctly set.

The lowest percentage other than zero at which your light can be dimmed is considered a low-end trim. And high-end trim is the highest level you can set.


Hold the center button’s right side and the top button together for the first six seconds. On the switch, a flashing status light will be seen.

  1. Hold down the middle right button until the light stops dimming or until it turns off.
  2. Hold the center left button down until the light stops flickering to adjust.
  3. Hold the bottom button down until the status light stops flickering to save this setting.
  4. Tap the top button once to turn off the light to make sure that these procedures were successful in stopping your flashing problem.
  5. Tap brighter once more after that. The light ought to turn on.
  6. Repeat these instructions if your issue is still not resolved and the light is flashing.
