Hello. I am considering installing 18x LED downlights in our living room. Each downlight is 4.8w. I would like to control all the lights from 3 different switches and place a dimmer in series. The idea would be to turn on/off the lights using one of the switch and adjust the intensity with the dimmmer. I like the MK grid switch and dimmer but not sure what are their rating. Could anyone please suggest a suitable dimmer for what I d like to do please?
