“These lightbulbs state they’re compatible with the Lutrion Diva and MACL dimmers. I tried both of them and the lightbulb made an audible humming noise when dimming. The only solution I found was to use a Lutron MA-Pro dimmer and companion 3-way which is substantially more expensive. Overall I was disappointed that the listed dimmers I had already installed did not work and forced me to change out an entire house plus detached garage and apartment on my own dollar.”
