The Complete Guide to Under-Cabinet and Puck Lights
Under-cabinet and puck lights improve visibility, reduce shadows, and make everyday tasks easier. Whether you are upgrading a kitchen, improving a retail display, or planning a commercial workspace, the right lighting makes a noticeable difference.
At 1000Bulbs, we help customers cut through technical confusion and choose commercial-grade lighting that performs reliably. This guide explains what under-cabinet and puck lights are, how to use them correctly, how to select the right products, and what to consider when replacing older systems.
What Are Under-Cabinet Lights?
Under-cabinet lights are linear fixtures installed beneath cabinets to illuminate countertops and work surfaces. They are commonly used in:
Residential kitchens
Office breakrooms
Retail shelving
Workshops
Healthcare and laboratory prep areas
Most modern systems use LED technology because it offers higher efficiency, longer lifespan, and lower heat output than fluorescent or halogen lighting.
Benefits of LED Under-Cabinet Lighting
Even illumination across the entire surface
Reduced shadows while preparing food or working
Lower energy consumption
Longer operating life
Minimal maintenance
LED systems are especially beneficial for spaces that operate daily and require dependable performance.
What Are Puck Lights?
Puck lights are small, round fixtures designed for focused lighting. They can be surface-mounted or recessed and are often used when you want accent lighting or targeted brightness.
Common uses include:
Highlighting backsplashes
Lighting display cases
Illuminating shelves
Adding decorative lighting in kitchens
Because puck lights create concentrated beams, spacing and brightness levels must be planned carefully.
Under-Cabinet vs Puck Lights
Both options serve different purposes.
Linear under-cabinet lighting works best when you need:
Continuous, shadow-free task lighting
Full countertop coverage
A clean and uniform appearance
Puck lights work best when you need:
Accent lighting
Decorative highlights
Focused lighting on specific areas
Flexible placement
Many kitchens and commercial installations use both to create layered lighting that balances function and style.
Best Practices for Installation
Proper installation improves performance and safety.
Install Fixtures Toward the Front Edge
Mount lights closer to the front of the cabinet to minimize backsplash shadows.
Keep Color Temperature Consistent
Typical recommendations include:
2700K to 3000K for warm residential kitchens
3500K for neutral task lighting
4000K or higher for commercial prep spaces
Mixing color temperatures can create an uneven appearance.
Select the Right Wiring Option
Choose from:
Hardwired systems for remodels and commercial projects
Plug-in systems for easier retrofits
Direct wire fixtures for permanent installations
Confirm voltage requirements before installation.
Verify Dimmer Compatibility
If dimming is important, confirm that the LED fixture and dimmer are compatible. Not all systems work together.
How to Choose the Best Under-Cabinet or Puck Lights
Selecting the right product requires looking beyond wattage and focusing on performance.
Brightness Measured in Lumens
For task lighting:
Plan for 200 to 500 lumens per linear foot
Puck lights typically range from 150 to 300 lumens each
Color Rendering Index
Choose CRI 80 or higher for general use. For food prep or retail displays, CRI 90 provides better color accuracy.
Voltage and Driver Compatibility
Many puck lights require:
12V or 24V drivers
Dedicated LED drivers
Compatible transformers
Always verify compatibility when replacing halogen or xenon systems.
Certifications and Safety Compliance
Look for fixtures that are:
UL Listed or ETL Listed
Rated for damp locations if installed near sinks
Compliant with current electrical standards
Commercial projects should always confirm local code requirements before installation.
Replacement and Compatibility Considerations
Upgrading older lighting systems is common in both residential and commercial spaces.
Replacing Fluorescent Under-Cabinet Fixtures
Measure fixture length
Confirm voltage
Review mounting points
Consider full LED fixture replacement instead of retrofitting tubes
Replacing Halogen Puck Lights
Confirm voltage
Verify transformer compatibility
Measure cutout diameter for recessed models
If you are unsure, consult with a lighting professional before ordering replacement products.
A Smarter Approach to Under-Cabinet Lighting
Under-cabinet and puck lights are practical upgrades that improve safety, visibility, and energy efficiency. In kitchens, they create a well-lit workspace. In retail and commercial settings, they improve task accuracy and presentation quality.
The right solution depends on your layout, brightness requirements, voltage configuration, and installation preferences. Choosing commercial-grade LED products ensures durability, energy savings, and long-term performance.

Frequently Asked Questions
What is the best type of under-cabinet lighting for kitchens?
LED linear light bars are the most effective for kitchen task lighting because they provide consistent illumination across the entire countertop.
Are puck lights bright enough for food preparation?
They can be if spaced correctly and selected at the proper lumen output. For larger prep areas, linear lighting typically provides more even coverage.
Can I install under-cabinet lighting without hardwiring?
Yes. Plug-in systems are available and are often used in retrofit projects. Hardwired systems are recommended for remodels and commercial installations.
How long do LED under cabinet lights last?
Most commercial-grade LED fixtures operate between 30,000 and 50,000 hours depending on usage conditions.
Do under cabinet lights increase electricity costs?
LED under cabinet lighting uses significantly less energy than halogen or fluorescent fixtures and can reduce overall lighting costs.
Are under cabinet lights safe near sinks?
Yes, provided they are rated for damp locations and installed according to electrical code.
How do I replace old puck lights?
Measure the cutout size, confirm voltage, and verify transformer compatibility before ordering replacements.
