Under-cabinet lighting is the most impactful upgrade you can make in a kitchen. It eliminates the shadows cast by upper cabinets, providing essential illumination for prep work. At night, it serves as sophisticated ambient lighting that makes your entire kitchen feel warmer and more inviting.
Takeaway: LED light bars provide the most even, professional-looking illumination. We avoid puck lights for primary task areas because they create distracting “scalloped” light patterns on the backsplash.
Understanding the Options
There are three primary ways to light under your cabinets. Each has specific pros and cons.
| Type | Best For | Pros | Cons | Installation |
|---|---|---|---|---|
| Light Bars | Task lighting | Even, continuous light | Hardwired required | Moderate |
| Puck Lights | Accent lighting | Easy placement | Creates scallops | Simple |
| Tape Lights | Budget / Flexible | Very slim profile | Can fail early | Easy |
1. LED Light Bars (The Professional Choice)
Light bars are the gold standard for kitchen task areas. They are usually 8 to 24 inches long and offer a seamless line of light.
Recommended Product: GE Enbrighten Direct Wire LED Bar ($55 per 18-inch bar). This fixture is professional-grade. It requires hardwiring, which means no visible cords or bulky plugs. You can select the color temperature (e.g., 3000K or 4000K) to match your overhead lighting.
Pro-Tip: Install light bars toward the front edge of your upper cabinets. Mounting them toward the back casts shadows while you work and causes direct glare if your countertop is glossy.
2. LED Tape Lights (The Budget Choice)
If hardwiring is not an option, tape light is your best bet. It is essentially a flexible strip of LEDs with adhesive backing.
Recommended Product: Wobane Under Cabinet LED Flexible Strip ($25). It is incredibly simple to install. Peel the backing, stick it to the underside of the cabinet, and plug the power adapter into a wall outlet. It is dimmable, slim, and nearly invisible when off.
The weakness of tape light is longevity. Cheap adhesives often fail after a year or two, causing the strips to peel. Use a secondary mounting clip or a bit of extra-strength double-sided tape for a permanent hold.
Proper Lighting Placement and Spacing
Do not just stick lights randomly. Follow these rules for a professional look:
- Surface Reflectance: If you have glossy granite or marble countertops, be very careful. LEDs reflect intensely off glossy stone. Use dimmers to soften the effect, or choose “diffused” light bars that have a frosted cover to hide the individual diodes.
- Backsplash Interaction: Mounting lights too close to the backsplash highlights every texture and imperfection in the tile or stone. Moving them to the front edge focuses light on the counter, not the wall.
- The “Scallop” Effect: If you must use puck lights, space them exactly 8 to 12 inches apart to allow the light circles to overlap smoothly. Do not exceed 12 inches of spacing, or you will end up with dark gaps between lights.
How to Choose the Right Color Temperature
Your under-cabinet lighting must match your overhead lighting. If your kitchen has 3000K warm white overhead cans, install 3000K under-cabinet lights. Mixing 3000K and 5000K daylight in the same space makes the kitchen feel disjointed and uninviting.
Quick Reference:
- 2700K - 3000K: Warm, cozy, matches traditional incandescent bulbs.
- 3500K - 4000K: Neutral, clean, excellent for task-heavy kitchens.
- 5000K+: Very clinical, blue-tinted. Generally avoid this in kitchens unless you are a professional chef.

Installation Strategies
Hardwiring (Best): If you are renovating, hire an electrician to run cables inside the walls. The “no wire” look is worth every penny of the investment.
Plug-in (Easiest): If you are retrofitting, hide the cords inside the small gap between the cabinet and the wall or use a cord cover that matches your cabinetry color.
Dimmers: Never install under-cabinet lighting without a dimmer. The light intensity you need for dicing onions is far too bright for late-night kitchen visits. A simple $15 plug-in dimmer switch for tape lights or a wall-mounted dimmer for hardwired bars is essential.
Integrating With Other Kitchen Lighting
Under-cabinet lighting is only one part of the puzzle. You need a complete “layering” approach.
- Task: Under-cabinet lights handle the counter work.
- Ambient: Overhead recessed cans or flush mounts provide general light.
- Feature: Pendant lights over the kitchen island serve as a focal point.
For the island area, read our guide to the best pendant lights for kitchen islands. If you need to refresh your overhead lighting, our comparison of recessed vs track vs surface mount lighting will help you choose the right fixtures. Finally, understand the broader concept of layering in our guide on how to layer lighting.
The bottom line: Choose LED light bars for the best performance, mount them at the front edge of your cabinets, and always include a dimmer switch. This configuration provides the functional task light you need and the sophisticated look you want.
