Puck lights are compact, disk-shaped light fixtures commonly used for under-cabinet lighting, closets, display cases, and accent lighting in modern homes. Their sleek design and directional illumination make them a stylish and functional lighting choice. However, like all electrical fixtures, puck lights eventually need replacing due to age, wear, or malfunction.
Whether you're upgrading to a more energy-efficient LED puck light or simply replacing a broken one, this guide covers everything you need to know—from identifying your type of puck light to a safe and clean installation.
🔍 What Is a Puck Light?
Before we begin the replacement process, let’s quickly review what a puck light is. Named for its resemblance to a hockey puck, a puck light is a small, round light fixture that can be:
- Battery-powered
- Plug-in (AC powered)
- Hardwired (connected to your home’s electrical system)
The replacement process will depend on which type you’re working with.
🧰 Tools & Materials You’ll Need
Here's a checklist of items you might need for this project:
| Tool/Item | Purpose |
|---|---|
| Screwdriver (Phillips/Flathead) | To remove old fixtures and secure new ones |
| Wire strippers | For stripping insulation from wires (hardwired only) |
| Wire nuts | For safe wire connection (hardwired only) |
| Voltage tester | To ensure power is off (hardwired only) |
| Replacement puck light | Choose one with the same size/type |
| Drill (optional) | For creating new holes if needed |
| Double-sided adhesive (optional) | For mounting battery lights without screws |
| Fresh batteries | For battery-operated puck lights |
🛠️ Step-by-Step Instructions for Replacing a Puck Light
STEP 1: Identify the Type of Puck Light
Look closely at your current puck light setup:
- Battery-powered? You’ll find a removable battery compartment.
- Plug-in? Look for a power cord connected to an outlet.
- Hardwired? These are usually installed directly into your home's electrical system, without visible wires or plugs.
⚠️Caution: If your light is hardwired, you’ll be working with live electrical connections. Always turn off power at the circuit breaker before proceeding.
STEP 2: Turn Off Power (for Plug-in or Hardwired Only)
If your puck light is hardwired or plug-in:
- Unplug the unit if it’s a plug-in type.
- Shut off the power at the circuit breaker if it’s hardwired.
- Use a voltage tester to double-check that no electricity is running to the fixture.
STEP 3: Remove the Old Puck Light
The removal method depends on how the light was mounted.
➤ Battery-Powered Lights
- Remove the light cover (usually snaps or twists off).
- Take out the batteries.
- Unscrew or unstick the puck from the surface.
➤ Plug-In Lights
- Unplug the cord.
- Unscrew the mounting bracket (if attached).
- Gently remove the light and disconnect any retaining clips.
➤ Hardwired Lights
- Unscrew the puck light from its surface mount.
- Carefully pull the fixture away to expose the wires.
- Use a screwdriver to disconnect the wire nuts.
- Separate and safely cap the exposed wires if you're pausing between removal and replacement.
STEP 4: Prepare the Area
Once the old light is removed:
- Wipe the surface clean of dust, adhesive residue, or dirt.
- If you're drilling new holes, mark your measurements carefully.
- Check the replacement puck light's mounting instructions—it may differ slightly in size or layout.
STEP 5: Install the New Puck Light
➤ Battery-Powered Installation
- Mount the light using included screws or double-sided tape.
- Insert fresh batteries.
- Attach the lens/cover and test the light by pressing the switch or using a remote (if applicable).
➤ Plug-In Installation
- Align the mounting bracket with the holes (you may need to drill new ones).
- Attach the puck light securely using screws.
- Plug the cord into a nearby power outlet.
- Switch it on to test.
➤ Hardwired Installation
- Match wire colors: black to black, white to white, ground (green or copper) to ground.
- Twist wires together and secure with wire nuts.
- Tuck the wires neatly back into the junction box or wall cavity.
- Mount the puck light with screws.
- Restore power at the circuit breaker and test the fixture.
⚠️ If you're uncomfortable with electrical work, consider hiring a licensed electrician.
STEP 6: Test and Adjust
- Turn on the light.
- Confirm it functions properly.
- Adjust the light's angle if it's directional.
- For smart or dimmable puck lights, sync them with your system or remote.
🆚 Should You Upgrade?
If you're already replacing a puck light, you might want to consider upgrading to:
- LED Puck Lights – Low energy use, long lifespan, and minimal heat.
- Rechargeable Wireless Models – Ideal for renters or areas without outlets.
- Smart Puck Lights – Controlled by remote, app, or even voice assistants.
Modern options also include touch-sensitive controls, motion sensors, and dimming capabilities for convenience and energy efficiency.
🏁 Final Thoughts
Replacing a puck light is a relatively quick and satisfying home improvement task. Whether you’re improving your kitchen lighting or brightening a dark closet, a fresh puck light can make a big visual and functional difference. Just remember to choose the right type and take the necessary safety precautions, especially when working with electricity.
