I am having an issue with my Cree BR30 (SBR30-06527FLFD-12DE26-1-13) bulbs buzzing. I have tried a LUTRON PD-6WCL-WH dimmer and also a GE 12724 dimmer. Both dimmers cause the Cree LEDs to buzz. The GE dimmer will only buzz when I dim the lights. When turned to 100% there is no buzz. The Lutron dimmer will buzz at all settings. The Cree website shows the Lutron dimmer is compatible. Does anyone have any suggestions that I can try?
