If you’re looking to update your home or office lighting, installing can lights may be an excellent option. Can lights, also known as recessed lights, are sleek and modern-looking light fixtures that sit flush with the ceiling. They provide both ambient and focused illumination, making them a popular choice for many spaces.

However, before installing can lights in an existing ceiling, you’ll need to understand the wiring involved. In this guide, we’ll walk you through the process of wiring can lights in an existing ceiling step-by-step.

Step 1: Choose the Right Can Lights

The first step is to choose the right can light fixtures for your space. At Rodec Lighting, we offer a wide range of LED Ceiling Lights that vary based on size, shape and type of bulb used (GU10 or MR16).

It’s essential to consider factors like spacing between each fixture and how much wattage each bulb consumes when selecting your fixtures. You also want to ensure they meet all necessary safety guidelines.

Our website provides detailed specifications for each product make it easier to select precisely what you need based on your space dimensions.

Step 2: Map Out Your Plan

Once you’ve selected your can light fixtures, map out where you want them installed on your ceiling using appropriate tools like laser levels or measuring tape but keep in mind local electrical codes requirements during planning phase contribute enormously towards avoiding any issues later down the line so read up before proceeding.

Also check if there are any obstacles such as pipes or ductwork in between joists which could affect positioning of the cans – adding these details into blueprints will also help contractors who might be bidding on this job gauge what work environment they’re getting into well beforehand.

Step 3: Cut Holes & Install Boxes

To install recessed lighting into an existing drywall ceiling or plaster, you’ll need to cut holes in the positions that you’ve mapped out. You can then proceed to installation of junction box through these openings.

The junction box provides a secure fix for the light fixture, with all the electrical connections enclosed within it. It also ensures that there is no energy loss from poor contact or loose wiring over time.

Use a drywall saw and gloves when cutting into drywall ceiling as dust from the material can be hazardous to your health without proper protection.

Step 4: Wire Your Can Lights

Now its time install wire into each junction box according to their respective color coding and connect them one by one firmly with an appropriate gauge wire nut.

As always make sure power source is disconnected at breaker panel before handling any wires.

Here’s how:

1) Strip off about half an inch of insulation off both ends of wire
2) Twist exposed end of supply wire around middle screw on bottom terminal
3) Connect remaining black (hot) wires together using wire nut
4) Repeat step 3 with white (neutral), red and green wires
5) Use cable staples to attach cables permanently in position

Step 5: Attach Trim & Bulbs

After wiring all fixtures correctly, assemble trims onto each bracket which gives lights a seamless appearance against ceiling before selecting bulbs suitable for selected fixtures like MR16 LED bulbs or GU10 LED bulbs ensuring correct wattage rating as well.

Finally, insert each bulb into corresponding socket gently until it clicks securely into place.

Congratulations! By following these five steps, you’ve successfully wired your recessed lighting fixtures in your existing ceiling. With our range of energy-efficient LED Ceiling Lights available at Rodec Lighting combined with this guide – you’re now ready to enjoy low-cost lighting solutions designed specifically for today’s environment-conscious consumer!

Professional Tips

  • Make sure power sources are disengaged before starting
  • Always use proper gauged wire nuts when connecting wires
  • Take note of local electrical codes and make sure you stay in compliance.

By following these tips, your installation will go smoothly and safely.


FAQ 1: Can I install can lights in an existing ceiling without cutting into the drywall?

Answer: Yes, it is possible to install can lights without cutting into the drywall. You can use remodel or retrofit recessed lighting kits that are designed specifically for installation in finished ceilings. These kits come with mounting brackets that allow you to attach the light fixture directly onto the surface of the ceiling between joists.

FAQ 2: What type of wire should I use when wiring can lights?

Answer: It is recommended to use a 14-2 electrical wire if you’re using a standard 15-amp circuit breaker. If your circuit breaker is rated at 20 amps, you will need to use a heavier gauge wire such as 12-2 cable. Always follow local building codes and consult with an electrician if you’re unsure about which kind of wire to use.

FAQ 3: How many can lights do I need for my room?

Answer: The number of cans needed depends on various factors, including room size, ceiling height, purpose of lighting (e.g., ambient or task lighting), and personal preference. A general rule of thumb is to space out recessed lights evenly across the ceiling at intervals equal to half the ceiling height (e.g., if your ceiling height is eight feet high, space out your cans four feet apart). For more specific guidelines or recommendations on how many cans to install in a particular space or project, consulting with an electrician or lighting designer may be helpful.
