Introduction to Under Cabinet LED Lighting

Hey there If you're thinking of adding some under cabinet LED lighting to your kitchen, you're in the right place. This guide will walk you through the process step-by-step, making it easy to understand and do yourself.

Planning Your Undercabinet LED Lighting Installation

Measure Your Cabinet Space

First, measure the length of each cabinet section where you plan to install lighting. Add these measurements together to figure out how much LED strip you'll need. It's a good idea to buy a bit more than you think you'll need, just in case.

Choose the Right LEDs

When picking out your LEDs, think about brightness (at least 200 lumens per foot), color temperature (warm white or cool white), and whether they can be cut to size. For example, if you want even lighting under your cabinets, look for strips with 60 LEDs per meter.

Gather Tools and Materials

You'll need some basic tools and materials like cleaning supplies, a dimmer switch, drill, drywall saw, electrical tape, fish tape, LED strip lights, power supply, scissors, screwdriver, staples, and wire strippers.

Preparing for Installation

Safety Precautions

Before you start, make sure to follow these safety tips: turn off the power at the breaker, use a voltage tester, and wear safety glasses when drilling or cutting. This will keep you safe during the installation process.

Clean and Prep the Cabinet Surface

Clean the cabinets with a degreasing cleaner and wipe them down with rubbing alcohol. Let them dry completely before you start installing the lights. This step is crucial for a smooth and even lighting installation.

Step-by-Step Installation

Step 1: Feed Up the Tape

If you need to install a remodeling wiring box above an upper cabinet, do it now. Turn off the power at the breaker, check with a voltage tester, and pull out the outlet to access the wiring. Use a fish tape to feed the wires through the knockout and out the new hole in the drywall.

Step 2: Pull Down the Wire

Strip the insulation off the wire, hook the ground to the fish tape, and pull it through until you expose about 10 inches of wire. Cut and strip the ends of the pigtails and the 12⁄2 wire. Join the wires with wire nuts and rewire the existing outlet.

Step 3: Add the Dimmer

Cut the 12⁄2 wire and thread it through a remodeling box. Install the box, strip the wires, and attach them to the new outlet. Add the power supply’s red and black wires to the inputs on the wireless dimmer and secure the connection.

Step 4: Plug in the Power Supply

Place the power supply and dimmer on top of the upper cabinets and plug in the power supply. Cut a length of 18⁄2 solid-core wiring to reach from the dimmer down the back of the cabinets.

Step 5: Wire Up the Terminal

Cut the red and black wire to reach the center underneath the corner cabinet. Add the wires to the terminal and tighten the setscrew. Branch the wiring to cover both walls of an L-shaped kitchen.

Step 6: Cut the Tape

Measure and cut the LED tape across the center of the copper contacts using scissors. Repeat for the other wall of cabinets.

Step 7: Wire Up the LEDs

Use LED tape-light extension connections to send power to both walls. Peel away the adhesive backing, slide the tape into the connector, and secure the connection. Repeat for the other wall of cabinets.

Step 8: Mount the LED Strips

Wipe the undersides of the cabinets with denatured alcohol. Peel off the backing from the LED tape and press it in place under the straight run of cabinets. Ensure it’s aligned with the holes drilled earlier.

Step 9: Hide the Wires

Use wire clips or cord hiders to secure and hide the wires along the lip of the cabinet doors or inside the cabinets.

Step 10: Test and Finalize

Test the LED strips to ensure they're working properly. Plug in the power supply, turn on the switch, and adjust the dimmer to your desired brightness level. Make sure all connections are secure and the lights are evenly distributed.

Additional Tips

Drilling Holes and Running Wires

When drilling holes for wires, use a paddle bit or an oscillating tool for precise cuts. Ensure holes are just large enough for wires to pass through without damaging them. Typically, holes should be at least 1 1/4 inches from the edge of studs or joists.

Using Diffuser Channels

To enhance lighting, consider using aluminum or plastic diffuser channels. These help soften and spread light more evenly, preventing LED dots from reflecting on shiny surfaces. This step can significantly improve your under-cabinet lighting system’s aesthetic and functionality.

Securing the LED Strips

Once wires are in place, secure LED strips using double-sided mounting strips or foam tape. Make sure strips aren’t too close to the front edge to avoid casting shadows. Proper placement ensures even distribution of light without creating unwanted shadows.

Troubleshooting

As with any electrical installation, troubleshooting is essential. Check connections for secure contact, verify polarity, and replace any damaged strips or connectors if you encounter issues like flickering or non-functioning sections. Regularly inspecting connections and wiring can help prevent future problems and keep your system running efficiently.

Enhancing Your Installation

To take your under-cabinet lighting to the next level, consider adding motion sensors, color-changing LEDs, or integrating lights with your smart home system. These features can add significant functionality and convenience to your kitchen or workspace. Motion sensors can automatically turn lights on and off based on movement, while color-changing LEDs can adjust color temperature to suit different moods or tasks.

Maintenance

Regular maintenance is key to keeping your LED under-cabinet lighting system in good condition. Clean LED strips with mild solutions to remove dust and debris. Inspect connections and wiring regularly to ensure they are secure and not damaged. Test the dimmer switch to ensure the system remains in good working order. By following these maintenance tips, you can extend the lifespan of your LED strips and keep them performing optimally.

Conclusion

Installing LED strip under cabinet lighting is a straightforward process that requires careful planning and execution. By following these steps—drilling holes, using diffuser channels, securing LED strips, troubleshooting potential issues, enhancing your installation with smart features, and maintaining your system—you can create a beautifully lit and functional kitchen or workspace. Always remember to follow safety guidelines and building codes to ensure a safe and efficient installation.
