Before you start installing under-cabinet lighting, it’s essential to understand the various options available. Under-cabinet lighting comes in several types, and the right choice for your space will depend on the desired effect, functionality, and style.

Types of Under-Cabinet Lighting

LED Strip Lights

LED strip lights are one of the most popular choices for under-cabinet lighting. These flexible strips consist of small LEDs that are mounted on a flexible tape. LED strip lights can be cut to fit any length and offer a sleek, modern look. They are also energy-efficient, have a long lifespan, and provide consistent lighting.
Puck Lights

Puck lights are small, round fixtures that emit focused light. These are ideal if you want to highlight specific areas, such as a countertop or workspace, with brighter, more concentrated light. Puck lights can be mounted either directly to the underside of cabinets or within a small housing for a more recessed appearance.
Recessed Lighting

Recessed lights are installed within the cabinet itself, creating a clean, almost invisible look. This type of lighting provides a sleek and minimalist aesthetic. While recessed lighting is typically used for general ambient lighting, it can also be installed under cabinets for a more uniform light spread.
Fluorescent Lights

Fluorescent under-cabinet lighting provides bright, even light. However, this type of lighting is becoming less popular due to the energy inefficiency and limited design flexibility compared to LEDs. Nevertheless, it can still be an option for larger projects or areas where bright, even lighting is needed.
Xenon Lights

Xenon lighting is another choice, known for its bright, white light. While more energy-efficient than halogen, xenon bulbs emit a warmer tone than LEDs, making them a good choice for creating a cozy atmosphere. However, xenon lights tend to generate more heat than LEDs and can be more expensive to run.

Factors to Consider

When selecting your under-cabinet lighting, keep the following factors in mind to ensure the right choice for your home:

Brightness (Lumens): Measure the brightness of the lights in lumens, not watts. LED lights typically provide the best balance between efficiency and brightness, with some models offering adjustable brightness settings.
Color Temperature: Choose a color temperature that complements your space. For instance, a warmer color temperature (around 2700K) works well in kitchens or living rooms, while cooler tones (4000K or above) are ideal for task lighting in workspaces.
Wiring and Power Supply: Determine whether you want a battery-powered or hardwired system. A hardwired system requires electrical knowledge to connect to the existing electrical setup, while battery-powered options can be easier to install but may require frequent battery changes.

Step-by-Step Guide to Installing Under-Cabinet Lighting

Now that you understand the different lighting options, let’s dive into the installation process. The steps outlined below will guide you through installing under-cabinet lighting, whether you’re using LED strip lights, puck lights, or any other type.

Tools and Materials Needed

Before you begin the installation, gather the necessary tools and materials. You’ll need:

Under-cabinet lighting kits (LED strips, puck lights, or other desired lights)
Measuring tape
Screwdriver
Pencil
Wire cutters and wire strippers
Drill with appropriate bits (if necessary)
Electrical tape (for connections)
Mounting clips or adhesive backing (for LED strips)
Power supply or transformer (if required)
Extension cord or hardwiring materials
Safety goggles and gloves

1. Plan the Layout

The first step in installing under-cabinet lighting is to plan the layout. Consider the following:

Placement of Lights: Determine where the lights will go under the cabinet. For example, LED strip lights can run the entire length of the cabinet, while puck lights may be placed in specific areas where you need more concentrated light, such as over the sink or stove.
Power Source: Decide where you’ll plug in or hardwire the lighting. If you’re using battery-powered lights, make sure they’re in a location that allows easy access for changing batteries. For hardwired options, you may need to connect the lights to an existing outlet or a dedicated circuit.
Spacing and Number of Lights: Measure the cabinet length and calculate how many lights you’ll need. With LED strip lights, you can cut the strips to the desired length, but for puck lights, you’ll need to ensure they’re evenly spaced for optimal coverage.

2. Prepare the Lights

Depending on the type of lights you’re installing, you may need to cut or adjust the fixtures before installation.

LED Strips: If you’re using LED strips, measure and cut them to fit the length of the cabinet. Most LED strips can be cut at marked intervals. Ensure that you’re only cutting where it’s indicated, as cutting in the wrong spot can damage the strip.
Puck Lights: If you’re using puck lights, ensure that they have the proper mounting hardware for your installation. Some puck lights have a magnetic base, while others require screws or adhesive backing.
Recessed Lights: If you’re using recessed lights, you’ll need to create small holes in the cabinet to fit the fixtures. Be sure to measure and mark where the lights will go so that you can drill the correct size holes.

3. Install the Lighting Fixtures

Once you’ve prepared your lights, it’s time to install them. Follow these general instructions based on the type of lights you’ve chosen:

For LED Strips:
1. Clean the surface of the cabinet where the LED strip will be installed. Use a mild cleaning solution to remove dust or grease.
2. Peel the adhesive backing off the LED strip (if applicable) and press it firmly onto the bottom of the cabinet.
3. For added security, you may want to use mounting clips to reinforce the strip, especially at the corners or where there are longer stretches of lighting.
4. Connect the strip to the power supply or transformer as per the manufacturer’s instructions.
For Puck Lights:
1. Use a pencil to mark the positions where the puck lights will be mounted.
2. Drill small holes for the mounting screws or use the adhesive backing if available.
3. Attach the puck lights to the cabinet, ensuring that they are evenly spaced and secure.
4. If using a transformer or power supply, connect the lights to the power source and check the wiring.
For Recessed Lights:
1. Measure and mark the spots where you’ll install the recessed fixtures.
2. Drill the appropriate-sized holes for the fixtures.
3. Insert the recessed lights into the holes and secure them.
4. Connect the lights to the power supply, ensuring all wiring is safely and securely attached.

4. Connect to Power

After the lights are mounted, the next step is to connect them to a power source.

Battery-Powered Lights: Simply insert the batteries into the light fixture and turn them on. Ensure that the battery compartment is easily accessible for future battery replacements.
Plug-in Lights: If you’re using plug-in lights, simply plug the light into an electrical outlet. If the cord is too long, you can hide the excess behind the cabinet or use clips to secure it neatly.
Hardwired Lights: For hardwiring, you may need to connect the lights directly to your home’s electrical system. If you’re unsure about electrical work, consider consulting a professional to ensure safety. Use wire nuts to secure the connections and electrical tape for added security.

5. Test the Lights

Once everything is connected, test the lights to ensure they work properly. If you’re using dimmable lights, test the dimming function to make sure it adjusts the brightness smoothly. If there are any issues, double-check the connections and make sure that the power supply is correctly installed.

6. Final Touches

After the lights are installed and functioning, take a step back and assess the overall look. You may want to adjust the angle of puck lights or re-position the LED strips to ensure even coverage. If you’re using smart lighting, you can configure the settings using an app to adjust the light color or schedule when the lights should turn on and off.

Conclusion

Installing under-cabinet lighting is an excellent way to elevate the look and functionality of your kitchen, bathroom, or any other area in your home. By carefully selecting the right type of lighting and following the installation steps outlined above, you can create a sleek, modern atmosphere that enhances both the beauty and utility of your space. Whether you’re a beginner or a seasoned DIYer, under-cabinet lighting is a manageable project that can add a touch of elegance to your home.
