I installed for 6 inch LED wafer recessed lights in the downstairs entertainment room I came out of an existing three gang switch box and fish my wires of the wall and ran my wires through the finish the ceiling there was no attic access so I had to cut holes but I did put the drywall back after shadow boarding the drywall then I installed a caseta smart switch so the customer controls the lighting from both entrances to the room due to the fact that I installed a remote to pair with the hardwired smart switch. I removed a chandelier in the dining/kitchen area then I fish the wire from the box down through the ceiling to the sink and I cut in a 6 inch LED wafer recessed light I attached the wires together so both the dining room light in the kitchen sink light will come on at the same time and I installed a Caseta smart switch so the customer could turn the lights on at the existing lighting location and also right next to the sink with the remote
