Installing Canless Recessed Lighting in an Existing Ceiling

Learning how to install canless recessed lighting in an existing ceiling is a rewarding skill for homeowners looking to enhance the look and feel of their living spaces. With a few simple steps and some safety precautions, the canless recessed lighting installation process can be easily tackled as a DIY project or with professional assistance.

Start by turning off the power at the circuit breaker to ensure a safe working environment. Next, mark and cut holes for each fixture on the ceiling using the supplied template and a suitable cutting tool, such as a drywall saw or Dremel Multi-Max. Be sure to double-check the size and placement before proceeding with installation.

After cutting the holes, prepare the junction box by removing any knockouts and inserting cable connectors. Feed the existing ceiling wires through the junction box and follow the color-coded quick connectors to connect black (hot) wires together, white (neutral) wires together, and bare (ground) wires with green (ground) wires.

Once all the wires have been connected, close up the junction box and prepare the canless recessed lighting fixture. Ensure the fixture is compatible with your ceiling type and that it has the necessary spring-loaded wings or clips to hold it securely in place. Attach the fixture to the existing ceiling by pushing it firmly upward until it clicks into place and sits flush with the ceiling surface.

Finally, test your new canless recessed lights by turning the power back on at the circuit breaker. Admire your handiwork and enjoy the sophisticated ambiance that your canless recessed lighting installation brings to your home.

Connecting and Securing the Canless Lights

Installing multiple canless recessed lights in an existing ceiling may require connecting them in a series, known as daisy-chaining. Proper daisy-chaining and securing of the lights result in a seamless and professional installation.
