All.
We purchased bunch of LED Retrofit FEIT RT56/927 and Lutron Dimmer DVWCL-153PH-WH.
However, Whenever we dim lights (4 cans of 2700K), we can hear buzzing sound.
Lutron dimmer is listed as compatible dimmer.
Lutron team, please provide compatible dimmer information to avoid buzzing sound.
We had this issue with a customer and another FEIT retrofit that is on "the list". We switched to a DVELV300PWH and this solved the problem. I believe FEIT may have changed their design or driver supplier causing this problem. I assume the new driver from FEIT is going to require a neutral wire from now on.
