Lutron Caseta switch used with Lutron MLC capacitor

[Hansjohnson123]

I have a flood light that is controlled by a lutron caseta on-off switch. The led was ghosting so I installed a lutron mlc capacitor which then caused a buzzing. Any ideas
Any feedback appreciated thanks

Found this. IDK if it will help or not.

The LUT-MLC was only designed to be used on Lutron digital switches. They should not be used on dimmers with the exception of ones rated for electronic low voltage, such as the Caseta PD-5NE. The LUT-MLC will only help with a light not turning completely off once the switch has been turned off. It will not help with other dimming issues caused by the type of light bulb, such as flashing or buzzing.

Is it the capacitor itself that's buzzing or is the Caseta switch doing it? The capacitor might have to be temporarily moved away from the switch using wires if it's hard to tell what's doing the buzzing.

That would be because forward phase dimmers have a fast risetime when they turn ON during each half cycle. This will cause a spike in current that may cause buzzing. Reverse phase dimmers instead turn ON at zero crossings of the voltage waveform and so such current spikes will not occur.
