Puck lights are small, versatile LEDs that add handy, wire-free light where you need it.

• Task lighting: Brighten kitchen counters, workbenches, and laundry areas with under cabinet lighting.
• Closets and pantries: Stick-on or magnetic lights make dark shelves easier to see.
• Hallways and stairs: Motion sensor options help guide nighttime movement.
• Display and decor: Highlight bookcases, art, and collectibles; RGB models add color.
• Bedrooms and kids’ rooms: Use dimmable or warm white settings as gentle night lights.

Many are battery operated or rechargeable, with remotes, timers, dimming, and color temperature options. For best results, mount on clean, dry surfaces and avoid high heat or damp areas unless the light is rated for those conditions. You can filter features and check pickup or delivery availability on Walmart.com.

Run time varies a lot because it depends on settings, battery type, and how often the lights are used.

• Battery type: Disposable AAA-powered lights and USB-rechargeable puck lights (often 1000–1200mAh) offer different capacities.
• Brightness and color: Higher brightness and colorful RGB modes generally use more power than warm white at a lower level.
• Modes: Motion sensor and timer functions can reduce on-time and help batteries last longer.
• Environment: Colder temperatures can impact battery performance.

To extend life, try dimming, enable auto-off timers, or use motion-activated modes where practical. Keeping spare batteries on hand or rotating rechargeable units can help. For estimated runtimes, check the product’s details on Walmart.com, as results may vary by model and usage.

Brightness for puck lights is listed in lumens, so that’s the best spec to compare.

• Lumen ratings: Many listings show around 50 lumens or 100 lumens per light; higher numbers generally appear brighter.
• Color temperature: Cool white can look crisper and brighter for tasks, while warm white feels cozier for ambience.
• Beam and placement: A wider beam spreads light, while positioning the light toward the front of a cabinet can reduce shadows on the counter.
• Quantity: Using multiple lights along a longer run can improve overall coverage.

Because rooms and surfaces vary, perceived brightness can differ. Check product pages for lumen specs, dimming options, and color modes, and consider your space’s size and finish to pick the right output.

Most puck lights are designed for simple, no-drill installs.

1. Prep the surface: Clean and dry the area so adhesive or magnets grip well.
2. Choose the mount: Use the included adhesive pads, mounting plates, or magnetic backs on metal surfaces.
3. Test placement: Temporarily position the light to check coverage before sticking it down.
4. Apply and hold: Press firmly for the time recommended in the instructions to help adhesion.
5. Wait, then use: Let adhesives set before adjusting settings or using the remote.

On painted or delicate surfaces, consider removable strips or mounting plates if provided. If you’re installing in a damp area, confirm the light is rated for that environment. Product pages on Walmart.com outline the included mounting method and any extra tips.

Both work well—it comes down to how you’ll use them and where.

• Rechargeable (USB): Convenient when outlets are nearby. Fewer disposable batteries, and many list capacities around 1000–1200mAh. Good for frequent use. Plan occasional charging time.
• Battery operated (AAA): Quick to swap batteries, handy for hard-to-reach spots or infrequent use. Keep spare batteries on hand for convenience.
• Features: Both types can offer dimming, remotes, motion sensors, timers, and color options (warm/cool white or RGB).

Consider access to power for charging, how often the lights will be on, and whether you prefer swapping batteries or recharging. Check product details on Walmart.com for battery type, estimated charge times, and feature sets to match your space.
