Position the J-box: Place the remote J-box into the ceiling opening, ensuring it rests securely above the ceiling tile or drywall.
Install the Downlight: Connect the cable from the downlight to the remote J-box. Push the spring clips on the sides of the downlight upwards and insert the fixture into the ceiling hole. Release the clips to secure the downlight flush against the ceiling.
