The fan replaced an earlier fan. It took less than hour to install. Very easy. The lighting isn't a dimmer, but two colors: warm white, blue white, and a blend. Very useful. It even has a (moderately "common") app to control it: Smart Life. The price is very reasonable. The controller isn't connected directly to home wiring. I found it best to place an on/off switch in the previous dimmer outlet and then use the controller. It turned on/off easiest that way. Be happy. Buy this.
