How to Choose Under Cabinet Lighting | Fit, Light, and Power

Choose LED under-cabinet lights sized to the cabinet run, with enough brightness for tasks, a warm color temperature, and a power method that fits your wiring.

Under cabinet lighting is one of the fastest kitchen upgrades, but the options can feel endless. The right choice for how to choose under cabinet lighting comes down to five decisions: purpose, fixture form, power method, size, and light quality. Work through them in order and the right fixture becomes obvious.

Start With Your Purpose: Task Light or Ambience?

Lowe’s buying guide says to settle this first, because it drives every other choice. Task lighting means bright, even light on the countertop for chopping and reading recipes. Ambience means a soft glow that makes the kitchen feel warm at night. If you want both, that’s normal. Many people install bright task lights under the main prep areas and use a dimmer to drop them to mood lighting when needed — that single decision covers most kitchens.

Pick a Fixture Form: Bars or Pucks

• Light bars (linear strips) run the length of the cabinet and spread light evenly across the counter. Lamps Plus says the bar should closely match the cabinet width to avoid uneven coverage.
• Puck lights are round spotlights placed individually. Lamps Plus recommends spacing them 8–12 inches apart for even distribution, or farther apart if you want pockets of light rather than full coverage.

Bars win for task lighting; pucks win for accent lighting or for cabinets with obstructions where a long bar won’t fit. Fixture profile matters: Lamps Plus notes the fixture should be shallow enough to hide behind the cabinet face — a tall fixture that hangs below the wood line ruins the look.

Choose a Power Method: Plug-In, Hardwired, or Battery

• Plug-in lights are the easiest. They need an outlet within reach, and the Lowe’s guide says to confirm the power adaptor reaches the nearest outlet. The cord is visible unless you hide it.
• Hardwired lights connect directly to 120-volt house wiring, so there are no cords. The result is clean, but installation is more involved and you may want a licensed electrician.
• Battery lights need no wiring at all. They are ideal for rentals or quick installs, though you’ll swap batteries or recharge them regularly.

If you’re installing several light strips, Lowe’s recommends linkable fixtures so one power connection runs the whole set. This is the smart middle ground — one plug, multiple lights, no visible cord gaps between cabinets. For a tested roundup of cord-free options, our battery under cabinet lighting picks cover the best rechargeable fixtures for kitchens where outlets are scarce.

Match Brightness, Color Temperature, and Quality

Two numbers matter most: lumens (brightness) and kelvin (color warmth). If you prep food daily, aim for the higher end. Color temperature is about feel. Yale Appliance recommends fixtures rated at 2,700–3,200 kelvin for best effect. That range covers warm white to neutral white. Products at 3,000 K sit squarely in this zone and suit most kitchens; anything cooler can look clinical. Quality shows up in evenness. ColorsLED says high-CRI LEDs and dot-free diffusion reduce hotspots. CRI is the color rendering index — high CRI (90+) means colors look natural rather than washed out.

Install Safely: Power, Code, and Clearance

Safety comes before aesthetics. Lowe’s installation guide is clear: turn off power at the main fuse box or circuit breaker before starting. Electrical connections must comply with local codes and the National Electrical Code, and you should check with the municipal building department about permits. Older homes need extra care. A qualified electrician should assess the wiring before you hardwire anything new. Follow the clearance rules too. The mounting surface should be at least 1/2 inch thick, and you should allow about 3 inches of linking-cord space at both ends of fixtures. Protect wire insulation from sharp edges — a cut in the jacket can cause a shock.
