I used a similar RGBWW product for my kitchen cabinet lighting and it came out great. I used standard dimmers on the LED recessed can lighting. I actually didn’t go with the Fibaro RGBW controller (yet 
) My current setup was a kit that used a wireless handheld remote to change to whatever color or flash. Then I used a simply Zwave wall switch to turn it on-off. If I want to change the color I need to use the manual remote. It saved me money before I went all out and got the dimming RGBW controller.
