What are under cabinet LED strips and puck lights?

Under cabinet LED strips are linear, flexible light sources; puck lights are small, round fixtures that provide spot or accent lighting. Both illuminate countertops, but they differ in form factor, distribution, and installation.

Under cabinet LED strips are thin, often adhesive-backed circuits containing many small LEDs spaced along a tape. They cut to length at marked points and come in single-color, tunable white, or RGB options. Puck lights are discrete, usually 1.5–3 inches in diameter, with a concentrated LED emitter behind a lens or diffuser.

Common variants:

• LED strips: 12V or 24V low-voltage strips, 2835/3528/5050 chip densities, waterproof (IP65+) or non-waterproof.
• Puck lights: hardwired, plug-in, battery-operated, recessed or surface-mounted, with integrated lenses or frosted diffusers.

How do light quality and performance compare?

Compare lumens, color temperature, color rendering (CRI), and uniformity—strips deliver linear, even light; pucks create brighter points needing diffusion for even coverage.

Key metrics to evaluate:

• Lumens (brightness): Choose by task—300–700 lumens per linear foot is typical for countertop task lighting. Pucks may output 100–300 lumens each.
• Color temperature (K): 2700–3000K warm for cozy kitchens; 3000–4000K neutral for task accuracy; 4000–5000K for workshops.
• Color Rendering Index (CRI): Aim for CRI ≥ 90 for accurate food and surface color (important in kitchens and retail). The Lighting Research Center provides guidance on CRI and perceived color quality.
• Uniformity: Strips produce continuous lines of light and minimize shadows; pucks require spacing and diffusers to avoid “hot spots.”

Installation varies: strips are highly flexible but sensitive to voltage drop; pucks are simpler individually but can require multiple holes and wiring runs.

Practical installation differences:

• Mounting: Strips adhere to the cabinet bottom and can be recessed; pucks are surface-mounted or recessed using cutouts.
• Wiring: Strips typically use a single feed and mean running one driver; long runs need 24V to reduce voltage drop. Pucks often need daisy-chain wiring or individual connections to a power source.
• Power sources: Both use low-voltage drivers (12V/24V) or integrated drivers with plug-in adapters; battery pucks eliminate wiring but increase maintenance.

Actionable installation checklist

1. Measure run length and plan driver location—keep runs under recommended length for the chosen voltage.
2. Choose strip density (LEDs per foot) based on desired uniformity (e.g., 120 LEDs/meter ≈ smoother output).
3. Select compatible dimmers/controllers (PWM controllers for RGB/tunable, TRIAC for line-voltage if supported).
4. Test layout with temporary tape before permanent mounting.

Essential tools and materials:

• Voltage tester, wire stripper, low-voltage connectors or soldering iron, measuring tape, isopropyl alcohol for cleaning mounting surface.

Energy use, heat, and lifespan: which saves more?

LEDs (both strips and pucks) are highly energy-efficient compared to halogen/incandescent; lifespan and heat depend on quality, driver, and thermal management.

Energy and longevity facts:

• LEDs typically use 70–90% less energy than incandescent equivalents and last tens of thousands of hours. The U.S. Department of Energy documents substantial energy savings from LEDs over legacy lighting.
• Typical rated lifespans are 25,000–50,000 hours for consumer-grade LEDs; higher-quality modules with proper heat sinking last longer.
• Heat matters: strips mounted on metal channels (aluminum profiles) dissipate heat and extend life; puck lights with enclosed housings need adequate ventilation to avoid premature lumen depreciation.

Upfront costs vary: strips generally cheaper per linear foot and easier to hide; pucks cost more per fixture but may be reasonable for small runs. Long-term, LEDs reduce operating costs.

Typical price ranges (U.S., 2024 market averages):

• LED strip kits (decent quality, adhesive-backed, 12V): $10–$35 per 5‑meter roll.
• LED puck lights (hardwired or plug-in): $15–$60 per puck depending on features (CRI, dimmable, smart).
• Drivers/dimmers: $20–$100 depending on wattage and smart features.

Example ROI scenario: Replacing four 20W halogen puck fixtures (80W total) with LED equivalents at 15W total saves ~65W. At $0.15/kWh and 3 hours/day, annual savings ≈ $10.70; lifetime savings accumulate with reduced maintenance costs and longer LED life.

Aesthetics and ideal applications for strips vs. pucks

Choose strips when you want continuous, shadow‑free task lighting; choose pucks for spotlighting, accenting interiors, or when wiring multiple small zones.

Best-use scenarios:

• LED strips: Under-cabinet task lighting, toe-kick lighting, under-shelf continuous illumination, ambient soffit lighting, integrated modern cabinetry.
• Puck lights: Inside cabinets for display lighting, above small islands with segmented lighting needs, retrofit where only small cutouts are practical.

Design tips:

1. For visual continuity, use a frosted diffuser or high-density strips to avoid seeing individual LED dots.
2. Mount strips behind the cabinet lip (baffle) for indirect, glare-free light.
3. Space pucks closer (every 9–12 inches) if used for task lighting to minimize patchiness.

Controls, dimming, and smart home integration

Both strips and pucks can be dimmed and connected to smart systems; choose appropriate drivers and controllers to avoid flicker and ensure consistent color control.

Control options:

• Basic dimming: Use compatible low-voltage LED dimmers (check PWM vs. constant current/constant voltage compatibility).
• Smart control: Zigbee, Z-Wave, Wi‑Fi, or Bluetooth controllers work with strips and many smart puck systems for schedules, scenes, and voice control.
• Color tuning: Tunable white (CCT) or RGB/RGBW strips require specific controllers and offer temperature adjustments from warm to cool light.

Technical cautions:

• Mixing LED types on one driver can cause flicker or uneven output—match voltage and total wattage to driver ratings.
• Cheap dimmers and non‑LED-rated switches often cause buzzing or poor dimming range—purchase LED-compatible components from reputable manufacturers.

How to choose, measure, and install: step-by-step guide

Measure, select light type by function and style, size the power supply, test layout, and install with attention to heat management and wiring standards.

Step-by-step selection and installation

1. Define function: Task lighting (strips preferred), accent/display (pucks OK), mood/ambient (strips with dimmer).
2. Measure: Measure cabinet runs, depth, and mounting clearance. Determine visible vs. hidden mounting zones.
3. Choose specs: Select lumens/ft, CRI ≥ 90 for color accuracy, and color temperature that matches the room (typically 3000K–3500K for kitchens).
4. Size the driver: Add up total wattage + 20% buffer. For long strip runs, choose 24V to reduce voltage drop, or feed at multiple points.
5. Create a trial layout: Temporarily mount strips/pucks and test at night for uniformity and glare before finalizing placement.
6. Mounting and wiring: Use aluminum channels for strips to improve heat dissipation and finish. Secure wiring with low-voltage connectors; maintain clear access for the driver.
7. Commission: Check dimming range, color consistency across runs, and measure light levels—aim for 300–500 lux on work surfaces for typical tasks.

Common pitfalls to avoid

• Ignoring voltage drop on long 12V runs—results in dimmer ends and color shift.
• Using non-LED dimmers or mismatched drivers that cause flicker.
• Mounting strips on painted wood without an aluminum channel, which can reduce lifespan.

Frequently Asked Questions

Quick answers to common buyer questions about compatibility, brightness, and retrofit options.

1. Can I mix LED strips and puck lights in the same run?

Yes, but avoid connecting different-rated fixtures to a single driver. Use separate drivers or compatible controllers and ensure voltage and dimming method match across devices.

2. How far apart should puck lights be for even lighting?

For countertop task lighting, space pucks every 9–12 inches if used as the primary light. If used for accenting, spacing can be wider (12–18 inches) depending on lumen output and diffuser quality.

3. Do LED strips require ventilation?

LEDs need heat dissipation to reach rated lifespans. Mounting strips in aluminum channels or on surfaces that conduct heat reduces thermal stress; fully enclosed housings can shorten life if heat builds up.

4. Will my existing dimmer work with LED under-cabinet lights?

Not always. Many legacy dimmers intended for incandescent loads produce buzzing or limited range with LEDs. Use LED-compatible dimmers or drivers rated for electronic low-voltage LEDs.

5. Are battery-powered puck lights a good option?

Battery pucks are convenient for retrofits or inside cabinet lighting without wiring, but expect ongoing battery replacement and lower brightness compared with hardwired LEDs. Consider rechargeable options if access is limited.

Final recommendation: Choose LED strips when you want continuous, shadow-free task lighting and a modern aesthetic; choose puck lights for targeted accenting, simple retrofits, or when individual replaceability is a priority. For most kitchen under-cabinet uses, a high-density, high-CRI 24V strip mounted in an aluminum channel with a quality dimmable driver offers the best balance of appearance, performance, and lifetime value.
