Turn off the circuit breaker for the Cooper Portfolio flush mount lights. This helps prevent accidental shock when replacing the light.
Set up a stepladder or step stool under the Portfolio flush mount light. It is necessary to reach the light comfortably without overstretching.
Grab the sides of the Portfolio light trim with your fingers. Pull the trim down slightly until it stops. The two spring clips should be visible between the trim and the light.
Press the two pieces of each spring clip together with your fingers. Pull the spring clips down and take the trim out of the ceiling. The light bulb is now accessible for changing.
