I have a few 6wcl's and the pro dimmer 10nxd and using Satco s9438 bulbs and getting a slight buzzing noise. I have a few cases of these bulbs and thought I would try them as I don't see them listed on the Lutron list. I doubt there is anything I can do to cut the noise but thought I would ask. I am using a neutral on the pro dimmer and get the same exact buzzing. Just want to confirm it is compatibility issue. Thank You
