Undercabinet Light Fixture Selection Guide

Undercabinet lighting turns a shadowed counter into a usable work surface, and the main decision is the voltage system, which sets how the fixtures wire and link. These fixtures sit in the Undercabinet Lighting family alongside Puck Lights and LED Undercabinet Accessories. The voltage specific subcategories, 120V LED Undercabinet, 24V LED Undercabinet, and 12V LED Undercabinet, hold the matched fixtures.

Choose the Undercabinet Voltage System

The voltage system sets the wiring, the driver, and how fixtures link. Match it to the install.

Output, Color, and Dimming

For counter task light, aim for even, bright light with good color so food and work look right, typically 3000K to 4000K and a CRI of 90 plus for kitchens. Linear bars give smoother, more even coverage than spaced pucks for a continuous run. Choose dimmable fixtures and a compatible control so the counter sets a bright task scene or a low accent glow at night.

Linking, Mounting, and Wiring

Measure the run under each cabinet and plan the link cords and corner connectors before ordering, since gaps show as dark spots. Low voltage 24V and 12V systems use a remote driver sized to the total load, while 120V bars wire directly and link end to end. Mount the bars toward the front edge of the cabinet to light the counter, not the backsplash. For spot accents and puck options, see Puck Lights.

Frequently Asked Questions About Undercabinet Light Fixtures

120V fixtures wire directly to line voltage and link end to end with no separate driver. 24V and 12V are low voltage systems that use a remote driver or transformer, which gives slimmer bars and clean longer runs. Match the system to the install.

Linear bars give smoother, more even light across a continuous counter, while puck lights create spaced pools of light. For general counter task lighting, linear bars are usually the better choice.

3000K to 4000K works well for kitchen counters, with a CRI of 90 plus so food and work look true. 3000K feels warmer and 4000K reads crisper and brighter.

Measure the run under each cabinet and plan link cords and corner connectors so the bars form a continuous line. Gaps between fixtures show as dark spots on the counter, so size the run before ordering.

Most are dimmable with a compatible control. Dimming lets the counter switch between bright task light and a soft accent glow. Confirm the fixture and dimmer are matched to avoid flicker.

Mount the fixtures toward the front edge of the underside of the cabinet so the light falls on the counter and work area rather than the backsplash. This gives the most usable task light.
