I installed 4 wafer led recess lights in customer front office room I then fished the switch leg down the wall and installed a caseta smart switch and linked the remote together with the hard wired switch so the customer can turn the lights on and off from both entrances to the room I then put all the drywall pieces back in the cut holes and screwed them to the joists Customer will have to have a different contractor to patch and paint the drywall Customer has a 1 year warranty
