I installed a Lutron wireless in-wall dimmer today. It seems to work well, excepting the LED ceiling light does not switch off completely. I have tried to adjust the low-end trim as per this document: http://casetawireless.com/Documents/...ced%20Inst.pdf
Lutron Caseta Model Number: PD-6WCL (as per bottom of the packaging box).
Ceiling Light: Patriot Lightning Dimmable LED https://www.menards.com/main/p-2395856-c-7243.htm
Note it is difficult to ascertain which LED exactly is in this device, as it's a sealed unit.
Thanks for your time.
