Have three switches on a circuit in master bedroom running 7 can lights in ceiling.
Some of the last convert to LED. They make some nice PAR38 reflector LEDS with a color temp equivalent to tungsten. Finally. So have thought of a dimmer on this for years. 3 switches. Could put a dimmer in one place that would control the whole circuit but that would not be good if you dimmed it then wanted to control from another location. So went all googly and came up with a Lutron product. Has to be a particular product that will work for LEDS. And has to be the RF version, not IR remote. The master dimmer uses one of the travelers as a data circuit to talk to the other dimmers and come to agreement as to the level that is wanted. Can dim from any location. You can put any number of dimmers/switches on a circuit. Has a preset dim button too. Gotta make sure to only have ONE master dimmer on the circuit. They all get unhappy if more than one is the master. This detail is very hard to find in the instructions. All of the switches have the dimmer controls. Only the master has the RF receiver. Have as many remotes as you want. Too several purchasing misfires (and one factory packing error), two very light at night tech support calls to Lutron (native American English speaker that actually knew his stuff). Blew some sparks when jamming all the wires into one of the outlet boxes (everybody does residential electrical work hot right, else how would you know of you blew a circuit breaker when jamming all those wires back in that little box). All the switches are finally in the wall, the grounds are even connected and the coverplates are on. This after about a month of bloody ended wires hanging out of the wall in three places and touching wires together to turn the lights on and off... I would recommend this system now that the pain of learning the different components and the wiring scheme is over. Two touches up and full brightness. One touch up and preset dimming. Turning them off makes them ramp down to a nice soft finish.
