How to Install LED Strip Lighting Behind Kitchen Cabinets – A Simple Step‑by‑Step Guide

If you’ve ever walked into a kitchen that feels flat and dim, you know the vibe can kill the whole day. A little glow under the cabinets can change that instantly. At GlowSpace Interiors I’m always looking for quick fixes that make a big impact, and LED strip lights are my go‑to. In this post I’ll walk you through everything you need to get that modern shine without hiring an electrician.

Why This Project Is Perfect Right Now

The holidays are coming, the weather is getting cooler, and we all spend more time at home. A warm, soft light under your cabinets not only looks sleek, it also makes food prep safer. Plus, LED strips are cheap, energy‑saving, and easy to hide. So why wait? Let’s get that glow on.

What You’ll Need (and Where to Find It)

Item	Why It’s Needed
LED strip kit (12V, cut‑to‑length)	The light source. Choose a kit with a remote or app for color control.
Power supply (adapter)	Turns wall AC into low‑voltage DC for the strips.
Double‑sided mounting tape (often comes with the strip)	Holds the strip in place.
Measuring tape	To get the right length.
Scissors (sharp)	For cutting the strip at the marked points.
Wire connectors or soldering kit (optional)	For joining pieces if you need extra length.
Screwdriver (if you need to open a cabinet)	To access the back of the cabinet.
Clean cloth	To wipe dust before sticking the tape.

All of these items are easy to find at a hardware store or online. I usually order a 5‑meter kit from a reputable brand; it’s long enough for most kitchens and you can always trim the excess.

Step 1: Plan Your Layout

Before you start peeling any tape, take a quick walk around your kitchen. Look at the length of each cabinet run and decide where you want the light to start and stop. Most people like the strip to run the full length of the cabinet underside, but you can also do a “U‑shape” around the back if you prefer a brighter look.

Tip from GlowSpace Interiors: Sketch a simple line on a piece of paper. Write down the measurements. This saves you from guessing and cutting the wrong length.

Step 2: Clean the Surface

Dust and grease are the enemies of good adhesion. Grab a clean cloth, a little bit of rubbing alcohol, and wipe the back of each cabinet where the strip will sit. Let it dry for a minute. This step takes a few seconds but makes a huge difference—trust me, I learned that the hard way when a strip fell off after a week.

Step 3: Cut the LED Strip to Size

Most LED strips have tiny scissors printed on the backing. Look for a dotted line or a small cut icon; that’s where you can safely cut. Measure the length you need, mark it lightly with a pencil, then cut. If you need to join two pieces, use the connectors that came with the kit or solder the wires together.

GlowSpace Interiors note: If you’re not comfortable soldering, the snap‑on connectors are a lifesaver. They click in place and hold the wires securely.

Step 4: Attach the Strip

Peel off the protective backing from the double‑sided tape and press the strip onto the clean cabinet surface. Start at one end and work your way across, pressing firmly as you go. Make sure the strip lies flat with no bubbles. If you hit a corner, gently bend the strip; the silicone coating is flexible enough to follow the shape.

Step 5: Connect the Power Supply

Now it’s time to bring the light to life. Plug the strip’s connector into the power supply adapter. Most kits have a simple “plug‑and‑play” design: the strip connector fits right into the adapter’s socket. Place the power supply in a hidden spot—under the cabinet or behind a nearby outlet. If you need to run the cord through a hole, use a small grommet to protect the wires.

Safety tip: Keep the power supply away from water sources and make sure the cord isn’t stretched tight. A little slack is fine and makes future adjustments easier.

Step 6: Test the Lights

Before you seal everything up, plug the adapter into a wall outlet and turn the strip on. If you have a remote or app, play with the colors and brightness. This is the fun part—watch your kitchen transform! If any section stays dark, double‑check the connections and make sure the strip isn’t cut at a non‑cuttable spot.

Step 7: Hide the Wires

Once everything works, tidy up the cords. Use small cable clips or zip ties to guide the wires along the back of the cabinet and into the power supply. If you have a gap between cabinets, you can run the cord behind the baseboard for a clean look. At GlowSpace Interiors we love using paint‑matched clips so they blend in.

Step 8: Enjoy Your New Glow

Step back, turn on the lights, and admire the soft, even glow under your cabinets. It adds depth to the room, makes the countertops look cleaner, and gives you a modern vibe without a full remodel. I love turning on the kitchen lights at night and seeing the gentle blue‑white glow—feels like a tiny starry sky right in the heart of the home.

Quick Troubleshooting

Problem	Fix
Some LEDs stay dark	Check the cut point; you may have cut at a non‑cuttable spot. Re‑join the strip or move the cut.
Flickering light	Make sure the power supply is rated for the total length of strip you installed.
Strip won’t turn on	Verify the adapter is plugged in and the outlet works. Try a different outlet.
Light is too bright	Use the remote/app to lower brightness, or add a diffuser strip (a thin frosted tube) over the LEDs.

A Little Story From GlowSpace Interiors

When I first tried this in my own kitchen, I was nervous about the wiring. I ended up tripping over a loose cord and almost knocked a pot off the stove. After that little “adventure,” I learned to keep the power supply tucked away and the cords secured. Now I can’t imagine a kitchen without that subtle glow. It’s become my go‑to trick for clients who want a modern look on a budget.
