Caseta compatibility question LUTRON PD-6WCL-WH

Hi,

I recently installed about 30 of these in my house: http://www.feit.com/products/retrofi...ledr56-927-mp/

Half are just on non-dimmer switches, but I have two rooms on LUTRON PD-6WCL-WH dimmers and two on non-caseta lutron manual slider dimmers.

The bulbs on the Caseta dimmers buzz faintly while the the bulbs on the non-caseta dimmers make no buzz at all.

Looking at the dimmer compatibility here: http://www.feit.com/compatibility-li...compatibility/ none of the Caseta models are listed... but I can't believe that there are no caseta dimmers available that will eliminate this buzz?

Is this what I need https://www.amazon.com/Lutron-PD-5NE...dp/B01M22SK1W/ and if so, why? Hard to swallow buying $200+ in new dimmers just to eliminate a little buzz.

Try changing the bulbs. Some bulbs buzz with Caseta dimmers, whereas others do not. I've found Cree dimmable LED bulbs do not buzz on the caseta dimmers. Green-lite bulbs seem to work in enclosed fixtures without buzzing (only LED bulb I found that was dimmable and rated for enclosed fixture, so good thing they didn't buzz).
