Looking to brighten up dark corners without overhauling your whole lighting setup? Puck lights might be just what you need. These small, round lights are perfect for adding focused light where you need it most—like under cabinets, inside closets, or around display shelves. They’re compact, easy to install, and surprisingly powerful for their size.
Whether you use puck LED lights for energy efficiency or battery-powered models for a tool-free setup, there’s a version for every space. Some stick right on, others mount in, and many even come with dimming or color-changing features for a more personalized touch.
In this guide, we’ll discuss the different types, their best use cases, how to install them, and how to choose the right ones for your home.
What Is a Puck Light?
A puck light is a small, round light that looks like a hockey puck—hence the name. But don’t let its size fool you. These compact lights pack a punch for accent lighting or brightening up small, shadowy spots. You’ll usually see them under cabinets, inside glass display cases, or even highlighting art on a wall.
What makes them so popular? Flexibility. Puck lights come in different styles: battery-powered, plug-in, or hardwired. These days, most people go for LED puck lighting because it lasts longer and uses way less energy. Some models stick on with adhesive (great for renters), while others screw in for a more permanent setup.
They’re not meant to replace your ceiling lights, but shine when it comes to focused lighting—think reading, prepping food, or showing off décor.
Types of Puck Lights
There’s more than one kind of puck light out there. Depending on your setup, budget, and how much brightness you need, you’ve got options. Here’s a quick breakdown of the main types—and what makes each one worth considering.
1. LED Puck Lights
For good reason, LED puck lighting is the most popular type right now. These lights are energy-efficient, long-lasting, and come in various brightness levels and color temperatures. If you’re looking for reliable lighting that doesn’t heat up or burn out quickly, puck LED lights are the way to go.
They’re perfect for everything from kitchen counters to closets. Many LED models are dimmable and have smart features like remote control or motion sensors.
2. Battery-Operated Puck Lights
Don’t want to deal with cords or wiring? Go for battery-operated puck lights. They’re super easy to install—just peel and stick. This makes them great for renters, temporary setups, or hard-to-reach spots where wiring would be a hassle.
The only tradeoff? You’ll need to replace or recharge the batteries every so often. But these are a solid pick if you want total flexibility without tools.
3. Hardwired Puck Lights
If you’re looking for a clean, professional look, especially in kitchens or custom shelving, hardwired puck lights are your best bet. These are installed directly into your home’s electrical system, so they turn on with a wall switch and don’t clutter the space with wires or plugs.
They take a little more effort to install, but they look great and work seamlessly once they’re in. Ideal for homeowners doing a remodel or new build.
4. Surface-Mounted Puck Lights
These lights sit on top of the surface you’re mounting them to. Surface-mounted puck lights are easier to install than recessed ones and still deliver that clean, low-profile look.
They work well in spots with insufficient depth to recess the light, like thin cabinet bottoms or shelves. Plus, they’re available in tons of styles to match your space.
5. Recessed Puck Lights
For the sleekest look possible, go with recessed puck lighting. These are installed into the surface, so all you see is the light, not the fixture. They’re perfect for modern kitchens, display cases, or anywhere you want lighting to be subtle but effective.
Just remember that installing recessed puck lights may require some drilling, so they’re better for permanent projects.
Where to Use Puck Lights
One of the best things about puck lights is how versatile they are. You can use them in any space where you need extra light, without the bulk of a prominent fixture. Here are some of the most popular spots to use them:
Under Cabinet Lighting
This is the most common use, and for good reason. Puck lights cabinet setups are perfect for adding task lighting in the kitchen. They light up your counters so you can prep food without straining your eyes. Plus, they make the space look high-end without spending a ton.
Depending on your needs and the permanence of the setup, you can choose plug-in, hardwired, or even battery-powered puck lights.
Closet and Wardrobes
Closets are often dark, and no one likes digging through shirts in the shadows. A few puck lights can completely change that. Stick-on battery-operated ones are ideal because you don’t have to mess with wiring.
Mount them on the closet’s ceiling or inside the wardrobe doors for instant brightness.
Bookshelves and Display Cases
Want to highlight your favorite books, artwork, or collectibles? Puck lights are great for this. You can’t tuck them above or inside your shelves to create that soft spotlight effect. It draws attention without being overwhelming.
LED puck lighting is best here—it gives off clear light and doesn’t get hot, so it’s safe around books and materials.
Puck Lights for Ceiling Use
While not meant to replace full overhead lighting, puck lights for ceiling use can still be handy. For example, in a hallway, small utility room, or even inside recessed niches, recessed or hardwired models work best for this since they blend in and don’t hang down.
This is a subtle, stylish option if you want ceiling accent lights without installing bulky fixtures.
Bathrooms and Vanity Areas
Installing puck lights near your mirror or vanity can help you get clearer lighting for grooming and makeup. They’re especially useful when paired with a dimmable feature that allows you to adjust the brightness to your liking.
Just choose a moisture-resistant model if you place them in bathrooms.
Accent Lighting for Decorative Areas
Do you have a cool piece of art on the wall? Or a cozy corner that could use a little pop? Puck lights work well as accent lighting. Stick them under floating shelves or behind decorations to give your space depth and character.
This is a great place to experiment with color-changing LED models, too.
Garage and Utility Spaces
Sometimes you just need functional lighting—nothing fancy. Puck lights get the job done in garages, tool sheds, or laundry rooms. Battery-powered ones can go on cabinet doors or above workbenches. And since they’re small, they don’t get in the way.
How to Install Puck Lights
Installing puck lights isn’t as complicated as you might think. Depending on the type you pick, it can be a total DIY win—even if you’ve never handled a screwdriver before. Here’s how it generally goes:
Step 1: Choose Your Location
Decide where you want to place the lights. Under cabinets? Inside a shelf? On the ceiling? Mark the spots with a pencil. Ensure the light beam will hit the area you want to illuminate, especially for task lighting.
Step 2: Pick the Type
- Stick-on (battery): Great for renters or quick installs.
- Plug-in: Good if you have an outlet nearby.
- Hardwired: Best for a clean look in permanent setups.
Step 3: Mount the Light
- Just peel off the adhesive backing for stick-on puck lights and press the light into place. Done.
- You’ll usually need a small drill or screwdriver to attach the mounting plate to the surface for screw-mount lights. Then, snap or screw the puck light into the plate.
- For recessed puck lights, you’ll need to cut a hole the size of the fixture using a hole saw or drill bit. This step is a bit more advanced but gives a sleek result.
Step 4: Connect the Power
- Plug-in lights: Just plug them into the nearest outlet.
- Battery-powered: Insert the batteries before mounting.
- Hardwired lights: Unless you’re confident with wiring, it’s safest to call a licensed electrician. These connect directly to your home’s power and often to a wall switch.
Step 5: Test and Adjust
Turn the lights on to make sure everything works. Adjust the angle or position if needed before finishing up.
Tip: If using multiple puck lights, space them evenly for a balanced look. Around 8–12 inches apart usually works well for under cabinets or shelves.
Advantages of Using Puck Lights
Puck lights might be small, but they bring a lot to the table. Whether you’re looking to boost your home’s style or make specific tasks easier, here’s why these little lights are a wise choice:
Discreet and Space-Saving
One of the best things about puck lights is how low-profile they are. They tuck right under cabinets, inside closets, or on shelves without getting in the way. You get the light you need, without a bulky fixture stealing attention.
Easy to Install and Move
Stick-on versions are about as DIY-friendly as it gets. Even hardwired models aren’t too complex if you’ve got some basic tools. And if you go with battery-powered puck lights, you can easily move them around when you reorganize or redecorate.
Energy-Efficient (Especially LED Models)
Using LED puck lighting means you’re saving money on your electricity bill. LEDs use way less energy than traditional bulbs and last for years. That’s a win for your wallet—and the planet.
Adds Value and Visual Appeal to Interiors
Good lighting can completely change how a space feels. Install puck lights under kitchen cabinets, inside a glass case, or around artwork, and suddenly your home looks more polished, modern, and welcoming. That kind of upgrade adds both style and value.
Ideal for Both Task and Accent Lighting
Need bright light for chopping veggies? Or a soft glow to highlight your favorite book collection? Puck lights do both. They’re bright enough for close-up work but soft enough to set a relaxing mood when used as accent lights.
How to Choose the Right Puck Lights
Not all puck lights are the same, and picking the right one depends on what you need them for. Here’s what to think about before you click “add to cart.”
Room Type and Purpose
Start with where you’re putting the lights. Is it a kitchen? Closet? Bookshelf? Each space has different needs. For example, under-cabinet lighting usually needs brighter, more focused light, while shelves and display areas work better with a soft, warm glow.
Brightness and Color Temperature
When choosing puck lights, don’t just go by the size—brightness and color temperature make a huge difference in how the light feels.
Brightness is measured in lumens. The higher the lumens, the brighter the light. Here’s a quick guide:
| Area | Recommended Lumens per Puck Light |
| Kitchen counter (task lighting) | 200–300 lumens |
| Closet or pantry | 100–200 lumens |
| Accent lighting (shelves, décor) | 50–150 lumens |
For example, if you’re chopping veggies or doing detailed work, you’ll want something in the 250–300 lumen range. But if you’re lighting up a bookshelf or art piece, something softer (around 100 lumens) will do the trick.
Color temperature is measured in Kelvins (K), and it affects the tone of the light:
| Color Temperature | Light Appearance | Best Use |
| 2700K–3000K | Warm white | Cozy areas, bedrooms, and living rooms |
| 3500K–4100K | Neutral white | Bathrooms, closets, and display cases |
| 5000K–6500K | Cool white / Daylight | Kitchens, workspaces, utility areas |
If you’re aiming for a relaxed, soft glow, go warm. Cool white is ideal for crisp, clean lighting, like kitchens or craft rooms.
Power Source: Wired vs. Battery vs. Plug-In
- Hardwired: Clean look, but needs more effort to install.
- Plug-in: Easy setup if there’s an outlet nearby.
- Battery-powered: Cordless, great for renters or temporary setups—but keep extra batteries around.
Pick the one that matches your setup and how permanent you want the lighting.
Dimming Capabilities
Want more control? Look for dimmable puck lights. Some have built-in buttons, others have remote controls, and others even work with smart home setups. Dimming is great for setting the mood or saving power.
Size and Design Compatibility
Puck lights come in different sizes and styles. Some are slim and modern, others have a more classic look. Measure your space and make sure the lights won’t stick out or look awkward. If you’re going for a recessed look, double-check the cabinet’s or shelf’s depth.
Control Options (Switch, Remote, Motion Sensor)
- Switch-controlled: Great for hardwired setups tied to a wall switch.
- Remote control: Makes it easy to turn lights on/off or dim from a distance.
- Motion sensors: Super handy for closets, pantries, or bathrooms. The lights turn on when you walk in.
Choose the control style that fits your daily routine. No one wants to crawl under a cabinet just to press a button.
Color-Changing Puck Lights
If you want mood lighting, this is where things get fun. Many LED puck lights now come with dimmable features and color-changing modes. You can switch from bright white task lighting to a soft, warm glow or add colors like blue, red, or green for a playful touch.
Some models let you cycle through colors or set timers for automatic changes. These lights are perfect for bedrooms, game rooms, or any space where you want lighting to do more than just “turn on.”
Maintenance and Troubleshooting
Puck lights don’t need much upkeep, but a little attention now and then keeps them shining bright. Here’s how to keep things working smoothly—and what to do if something goes wrong.
Cleaning and Battery Replacement
Dust and grime can build up, especially under cabinets or closets. To clean your puck lights:
- Turn them off (and unplug or remove batteries if needed).
- Wipe the surface gently with a soft cloth—microfiber works best.
- For tougher spots, a slightly damp cloth with mild soap is fine. Just avoid getting moisture inside the light.
If you’re using battery-operated puck lights, swap the batteries as soon as the brightness disappears. Most models use AA or AAA batteries; replacing them only takes a minute. Always keep spares nearby if you rely on these lights daily.
Common Issues and Fixes
Light won’t turn on?
Check whether the batteries are fresh or the unit is securely plugged in. Double-check the wiring connection for hardwired versions—or call an electrician if needed.
Light flickers or dims randomly?
Loose connections, weak batteries, or poor contact with the power source could cause this. For plug-in or battery models, try removing and reinserting the power or batteries to reset the connection.
Remote not working?
Make sure it has fresh batteries. Also, check the sensor range—some remotes need a clear line of sight to work properly.
Motion sensor not detecting?
Clean the sensor lens gently. Sometimes dust or placement can interfere with how well it picks up movement.
If the problem sticks around, it might be time for a replacement. Most puck lights are affordable, so swapping in a new one is usually easy.
