Why Choose LED Under Cabinet Lighting?

LED under cabinet lighting has become the preferred choice for homeowners, interior designers, and even professional chefs. It offers energy efficiency, a sleek design, and practical brightness for cooking, reading recipes, or just creating a warm ambiance in your kitchen.

The advantages go far beyond aesthetics. LED under cabinet lights are cost-effective, emit less heat than traditional bulbs, and have an impressive lifespan—often lasting over 25,000 hours. If you're replacing outdated halogen or fluorescent fixtures, LED strips are a modern, efficient alternative.

Planning Your LED Strip Lighting Project

Before you install, careful planning is key. Begin by identifying the areas under your cabinets where lighting would be most beneficial. Most people choose to install strip lights beneath upper kitchen cabinets to illuminate countertops, but you can also install them in offices, workshops, or laundry rooms.

Measure the length of each cabinet section where the strip will be placed. Add an extra inch or two to your measurements to ensure complete coverage and accommodate connectors, if needed. Determine where your power source will be. If using a 110V power outlet, make sure it’s within reach of the lighting system or plan to install new wiring.

Choosing the Right LED Strip Lights

Not all LED strips are created equal. Look for strip lights specifically designed for under cabinet installations and compatible with 110V input. These are often described as plug-and-play kits or hardwire-compatible models. Check that the brightness level meets your needs. A good benchmark for task lighting is 300 to 400 lumens per foot.

Also, decide whether you want features like dimmability, color temperature options, or smart home integration. Dimmable white light is the most common and practical for kitchens. Warm white tones create a cozy environment, while cool white enhances clarity for food preparation.

Select a product that is UL-listed or certified for safety, especially when working with 110V power sources.

How to Install LED Strip Lights Under Cabinets Using 110V Power

The installation process will depend on whether you choose a plug-in or hardwired model. Here is a complete guide for both methods.

Step 1: Turn Off the Power

If you're planning to hardwire the lighting, turn off the power at the circuit breaker before starting. Safety should always come first when working with electricity.

Step 2: Prepare the Installation Surface

Clean the underside of your cabinets with a degreasing solution to ensure the adhesive backing of the LED strip lights adheres properly. Any dust, grease, or residue can weaken the adhesive.

Step 3: Attach the LED Strip Lights

Unroll the LED strip and test it to confirm it’s working before attaching it. Peel the adhesive backing and stick the strip underneath the cabinet along the front edge to avoid shadows. For added support, you can use mounting clips or brackets, especially for longer runs.

Cut the strip only at designated points if you need to shorten it. Most strips are marked with a scissor icon at cut lines, ensuring you don’t damage the circuitry.

Step 4: Connect to the Power Source

If you’re using a plug-in model, plug it into a nearby 110V outlet. You can use a cable management system to hide the cord for a neater appearance.

For a hardwired setup, connect the wires to an existing power line. Typically, this involves matching black (hot), white (neutral), and green or bare copper (ground) wires. Use wire nuts and a junction box to protect the connections.

In some cases, a transformer or power supply may be needed between the 110V outlet and the low-voltage LED strip. Always read the manufacturer’s instructions.

Step 5: Add a Switch or Dimmer

To control the lights more efficiently, consider installing a wall dimmer switch. Smart dimmers can also be connected to Wi-Fi or voice assistants like Alexa or Google Home. A basic inline switch will work for plug-in models, while wall-mounted dimmers are ideal for hardwired systems.

Step 6: Test and Secure the Installation

Once all wiring is connected, turn the power back on at the breaker and test the lighting system. If everything lights up correctly, secure any loose wires using clips or adhesive cable organizers. Make sure the lighting is evenly distributed without any dark spots or visible connectors.

Replacing Old Lights with LED Strips

If you're wondering how to replace under cabinet lighting with LED, the process is similar. Begin by turning off the power and removing the old fixture. Disconnect the existing wiring and mount the LED strip in the same location. Use the old power supply or install a new one as needed.

LED strips offer a slimmer, cleaner look compared to older fluorescent or halogen fixtures, and they generate far less heat. This makes them ideal for tight spaces and frequent use.

Common Installation Mistakes and How to Avoid Them

One of the most common errors is not measuring properly before installation. Always double-check your dimensions to ensure a perfect fit. Another issue is poor adhesion due to greasy cabinet surfaces. Clean surfaces thoroughly before attaching any adhesive.

Overloading a power source or skipping the use of a transformer when required can damage your LED strips. Always read product specifications and safety guidelines before connecting to a 110V supply.

Avoid installing the strips too close to the wall or too far from the cabinet edge, as this can create uneven lighting and harsh shadows.

Benefits of Kitchen Under Cabinet LED Lighting

Upgrading your kitchen with under cabinet LED lighting adds both functional and aesthetic value. You'll enjoy better lighting for meal prep, enhanced safety, and a modern look that can make even a small kitchen feel more spacious.

LED technology is also cost-effective in the long run. These lights consume less energy and last significantly longer than traditional lighting options. You can leave them on for hours without worrying about high electricity bills or frequent replacements.

Many homeowners also appreciate the flexibility of LED strip lights. You can install them in various areas beyond the kitchen, including bathrooms, home offices, display cabinets, and closets.

FAQs: How to Install Under Cabinet LED Lighting

How do I install under cabinet LED strip lights using 110V power?
You can either plug the strip lights directly into a 110V outlet or hardwire them into your home’s electrical system. For plug-in models, installation is as simple as sticking the lights in place and plugging them in. For hardwired setups, you’ll need to connect the wires to an existing power source using wire nuts and a junction box.

Do I need a transformer for LED strip lights?
Some LED strips are designed to run directly on 110V, while others require a transformer to convert high voltage to low voltage. Always check the product specifications before connecting to a power source.

Can I install under cabinet LED lighting without hiring an electrician?
Yes, if you're using plug-in LED strips. If you plan to hardwire the lights into your home’s electrical system, it’s best to consult or hire a licensed electrician unless you’re experienced with electrical work.

How do I remove old under cabinet lighting and replace it with LED?
Turn off the power, remove the old fixture, and disconnect the wiring. Install the LED strip in its place and connect it using the same wiring method, ensuring compatibility with the new LED system.

Are under cabinet LED lights dimmable?
Most are, but you need a dimmable driver and compatible dimmer switch. Check the manufacturer’s label before purchasing.
