Wall panelling is everywhere. You can't scroll through Instagram without seeing those sleek wooden slats or classic Shaker squares. But honestly? Most of them look flat. They lack that "wow" factor because the lighting is an afterthought—usually just a bright ceiling bulb that washes everything out. Panelling with LED lights changes the entire vibe of a room. It’s the difference between a DIY project that looks like a DIY project and a space that feels like a boutique hotel.
If you're thinking about adding strips or pucks to your walls, stop. Don't just stick them on. There is a specific way to do this so you don't end up with visible "dots" or a room that feels like a gaming cave from 2012. You want a glow. You want depth.
The glow is in the gap
The biggest mistake I see? People mounting LEDs directly onto the surface where you can see the tape. It’s distracting. To get that high-end look, you need to create a "pocket" or a shadow gap. This is essentially a small recessed area where the light can bounce off a secondary surface before it hits your eyes.
When you’re panelling with LED lights, the goal is indirect illumination. Think about a floating media wall. If you build a frame that sits two inches off the main wall, and you tuck the LED strip behind the lip of that frame, the light bleeds out softly. This creates a halo effect. It makes the heavy wood or MDF panels feel weightless. Designers like Kelly Hoppen have been using this "layered lighting" trick for decades to make rooms feel more expensive than they actually are.
Most people buy the cheapest 12V strips they can find on Amazon. Don't do that. 12V strips suffer from "voltage drop," which basically means the light gets dimmer the further it gets from the power source. If you’re doing a long run of wall panelling, use 24V strips or, better yet, COB (Chip on Board) LEDs. COB strips have way more diodes per inch, which gives you a seamless line of light without those annoying dark spots between bulbs.
Shadows are actually your friend
Wall panelling is all about texture. Whether it's fluted panels, wainscoting, or slat walls, the beauty is in the 3D nature of the material. If you light it from the front, you kill the texture. It becomes 2D.
By grazing the light—which means placing the LEDs very close to the wall and pointing them up or down—you highlight every single ridge and groove. This is why slatted wood walls look so good with top-down lighting. The light catches the edge of each slat and casts a long, dramatic shadow into the recessed part. It’s moody. It’s architectural.
You also need to think about the "Color Temperature." This is measured in Kelvins. If you go for 5000K, your living room will look like a dentist's office. It's too blue, too sterile. For a home, you’re looking for 2700K or 3000K. That’s the "Warm White" sweet spot. It mimics the glow of a sunset or a fireplace. It makes the wood grain pop.
Why smart controllers are non-negotiable
Let’s be real: fumbling for a tiny plastic remote that looks like it came from a 90s TV is annoying. If you’re going to the trouble of installing panelling with LED lights, you have to integrate the controls.

Zigbee or Matter-enabled controllers are the way to go in 2026. This allows you to sync your wall lights with your existing smart home ecosystem like Philips Hue, Apple Home, or Google Home. You can set "scenes." Imagine a "Movie Night" scene where your main lights go off, and your wall panels dim to a 10% golden glow. That's the level of polish we're aiming for.
And for the love of everything, hide the transformer. These "drivers" are bulky bricks. I’ve seen people do beautiful panelling jobs only to have a black power brick dangling near the baseboard. You need to plan a "comms cupboard" or a hidden hatch within the panelling to store these. They get warm, too, so make sure there’s a bit of airflow. Safety first.
Materials matter more than you think
Not all panels are created equal when it comes to light reflection. If you use a high-gloss paint or a shiny plastic panel, your LEDs will reflect like a mirror. You’ll see every single individual diode reflecting back at you. It looks cheap.
Go for matte or satin finishes. These finishes diffuse the light. They soak it up and spread it out. If you are using a material like Acupanel or similar felt-backed slats, the felt actually helps absorb the "spill" of the light, making the highlights on the wood even more pronounced.
Some people try to use neon flex. It’s trendy. It looks cool in a bar. But in a bedroom or a formal lounge? It’s often too intense. Stick to traditional strips hidden behind a diffuser channel. An aluminum channel with a frosted "milky" cover is your best friend. It protects the LEDs from dust and makes the light much softer.

The "Floating" illusion
One of the coolest things you can do with panelling with LED lights is the "recessed plinth." Basically, you stop your wall panelling about 4 inches above the floor. In that gap, you tuck an LED strip pointing downwards.
When you turn it on at night, the entire wall looks like it’s hovering. It’s a great trick for small hallways because it draws the eye to the floor edges, making the space feel wider. It also works as a perfect nightlight. You don't have to turn on the big lights to go to the kitchen for a glass of water; the "floating" floor light is enough to guide you without waking you up fully.
Putting it all together: The technical reality
Look, I'm not going to lie and say this is a 5-minute job. It requires planning. You need to know where your power outlets are. You might need to chase wires into the drywall.
- Calculate your wattage. Each meter of LED strip draws a certain amount of power. Make sure your power supply (the driver) can handle at least 20% more than what you need. This is called the "80% rule," and it prevents the driver from overheating and flickering.
- Think about the "CRI." Color Rendering Index. Most cheap lights have a CRI of 80. Food and skin look weird under them. Look for CRI 90 or higher. It makes colors look "true."
- The "Tail." Every strip needs a wire that goes back to the power. If you’re doing a huge wall, you might need to power the strip from both ends to keep the brightness consistent.
Actionable Next Steps
To get started with panelling with LED lights, don't buy anything yet. Start by grabbing a cheap flashlight. Wait until it’s dark, hold the flashlight against your wall, and point it upwards. Move it closer and further away. See how the shadows change? This tells you exactly where you need to mount your LED channels to get the look you want.
Once you’ve found the "sweet spot" for the light, measure your wall and draw a diagram. Mark where the wires will go. If you aren't comfortable with 110V/240V wiring, hire an electrician to install a recessed outlet behind where the panels will go. Then, you can handle the low-voltage LED side yourself.

Choose a COB LED strip in 3000K Warm White, pair it with a matte-finished wood or MDF panel, and ensure you have a dedicated space to hide the driver. This setup ensures your panelling isn't just a wall—it's a feature that defines the entire atmosphere of your home.
