Their energy efficiency, as they use less power compared to traditional lighting fixtures.
Their slim profile, which makes them almost invisible, creating a clean and modern look.
Types of Can Lights
Before adding can lights to an existing circuit, it’s essential to understand the different types available. The primary categories include:
New construction can lights, designed for installation during the building phase.
Remodel can lights, ideal for retrofitting into existing ceilings.
IC-rated can lights, suitable for installation in insulated ceilings.
Air-tight can lights, designed to prevent air leakage and reduce heat loss.
Preparation is Key
Before starting the project, it’s crucial to prepare the necessary tools and materials. This includes:
A voltage tester to ensure the power is off.
A drill with a hole saw attachment for creating holes in the drywall.
A fish tape or fish stick for pulling wires through the ceiling.
A can light housing and trim ring.
Wire connectors and electrical tape.
Evaluating the Existing Circuit
Before adding can lights to an existing circuit, it’s vital to evaluate the circuit’s capacity and ensure it can handle the additional load. This involves:
Checking the circuit’s amperage rating and the total wattage of the existing lights.
Verifying the type of wire used and its gauge.
Identifying the existing light fixtures and their wattage.
Determining the Circuit’s Capacity
To determine the circuit’s capacity, follow these steps:
Calculate the total wattage of the existing lights.
Check the circuit breaker or fuse box to determine the circuit’s amperage rating.

Upgrading the Circuit (If Necessary)
If the existing circuit is not capable of handling the additional load, it may be necessary to upgrade the circuit. This can involve:
Installing a new circuit breaker or fuse.
Upgrading the wire gauge.
Adding a new electrical panel or subpanel.
Installing the Can Lights
Once the existing circuit has been evaluated and upgraded (if necessary), it’s time to install the can lights. This involves:
Locating the Joists
Use a stud finder to locate the ceiling joists, as the can light housing will need to be secured to these.
Creating Holes for the Can Lights
Use a drill with a hole saw attachment to create holes in the drywall, ensuring they are centered between the joists.
Installing the Can Light Housing
Insert the can light housing into the hole, ensuring it is securely attached to the joist.
Connecting the Wires
Use wire connectors to connect the can light wires to the existing circuit wires, ensuring all connections are secure and meet local electrical codes.
Installing the Trim Ring
Install the trim ring, which will cover the edge of the drywall and create a finished look.
Testing and Finalizing the Installation
After completing the installation, it’s essential to test the can lights to ensure they are working correctly. This involves:
Turning the power back on at the circuit breaker or fuse box.
Verifying the can lights are functioning properly and not flickering.
Checking for any signs of overheating or electrical issues.
Final Inspection and Touch-ups
Perform a final inspection to ensure all connections are secure, and the installation meets local electrical codes. Make any necessary adjustments or touch-ups to the drywall or trim ring.
