LED Recessed Lighting: A Comprehensive Guide to Installing

  5. Conclusion


Recessed lighting fixtures provide a subtle way to illuminate your office as they are almost invisible from most angles, creating a low-profile look that hangs from the ceiling with only a trim ridge visible. These lights may also be referred to as canisters, and they are particularly popular in modern commercial areas  as they emphasize the clean architectural lines of the interior.

If you have a nearby power source, installing LED recessed lighting in the ceiling can be an easy DIY project. However, if setting up a power source is needed, there are options like wiring your own circuit or enlisting an electrician's help, which will take extra time. If you decide to go the DIY route, ensure that you fully comprehend each fixture's amp rating and that all recessed lights are located at a safe distance from your ceiling's joists. If you want to know about selecting, view here: Your Comprehensive Guide to LED Recessed Lighting Selection.

Materials and Equipment Needed

  • Recessed light

  • Electrical cable

  • Hole saw, or drywall jab saw

  • Stud-finder

  • Wire ripper

  • Wire stripper

  • Side-cutting pliers

  • Voltage tester

  • Breathing protection

  • Piece of plywood large enough to span a few rafters

  • Eye protection

Safety concerns

To ensure your safety while working on the electrical cable, first, switch off the related circuit breaker. If the installation of recessed lights is still pending, wait until it's completed before the final connection. Verify the circuits with a voltage tester.

When working above ceilings, it's crucial to wear breathing protection and avoid roofing nails that may protrude from the roof. Only make use of rafters or joists to move around, as stepping on the ceiling drywall might lead to a fall. When working in the attic, it is best to stand or recline on a plywood board.

Step-by-step guide

  1. Find your preferred recessed light size - Determine the size of the recessed lights you want to place by determining their preferred dimensions. There are several sizes offered in addition to the 2'x2', 2'x4', or 1'x4' standard sizes.

  2. Determine the layout - You need to select a layout for your recessed lighting - this is where you choose where to place the lights. Mark the location on the ceiling to ensure that they are evenly spaced and have the desired effect. You can also use this Free Recessed Lighting Calculator to help you determine.

  3. Mark your cutting line - Measure the diameter of your recessed light fixture and use a compass or a circle template to draw the circle where you want to cut your hole. Make sure it's centered on your chosen location and clear of any obstructions.

  4. Cut the hole - Use a drywall saw, reciprocating saw, or jigsaw to cut along the circle you've traced. Use steady and careful movements as you cut to avoid damaging the ceiling or any wiring.

  5. Run the supply wire to the ceiling hole - If the wire is already installed in another recessed light, open the junction box of the previous light and attach the wire. If the wire is coming from its own circuit, pull it down through the hole. If there is a standard electrical ceiling box already in place, it must be removed to install the recessed light.

  6. Connect the wire to the recessed light - Use a wire ripper to remove 4 inches of cable sheathing. Then, strip the coating from the wires within the sheathing. Pull the wire into the light's junction box and make the appropriate connections. A black wire from the light should be connected to the cable's black wire. In some cases, push-fit connectors with identifying colors may be present in the lights.

  7. Install the light - Gently lift the recessed light upwards and place it into the opening in the ceiling. It should fit securely without harming the surrounding drywall. Typically, recessed lights feature a clip system that fastens to the inside of the top of the ceiling.

  8. Add the trim and the bulb - Install the appropriate light bulb as directed in the instructions of the fixture. The options include choosing "A" bulbs, which require reflective trim. Alternatively, "R" bulbs already come with a built-in reflective surface, Halogens, which offer bright lights featuring a controlled beam, or energy-saving LEDs.

  9. Wire the circuit to the panel - Pull the electrical cable into the electric service panel, also known as the circuit breaker panel. Next, attach the wire to a circuit breaker that is suitable in size, usually 15 amps. Finally, insert the circuit breaker into a slot that is available on the service panel.
