Under-Cabinet Lighting: Brighten Counters the Right Way
Overhead kitchen lights cast shadows right where you work, leaving countertops dim while you chop, read recipes, or measure. Under-cabinet lighting fixes that by putting light directly on the work surface, but the wiring and mounting need to be hidden and tidy or the upgrade looks like an afterthought. Choosing between plug-in and hardwired, and between strips and pucks, trips up a lot of homeowners.
Under-cabinet lighting is about clean, even task light with the wiring kept out of sight. The first decision is plug-in versus hardwired: plug-in is simpler and avoids opening walls, while hardwired runs to a switch for a finished, cord-free look but is a bigger job. The fixture choice — continuous LED strips or tape for smooth, shadow-free light versus puck lights for focused pools — shapes the result. A pro plans placement near the front edge of the cabinet to light the counter rather than the backsplash, conceals the wiring, and ties everything to a switch or dimmer. Hardwired installs that add a new circuit or switch may require a licensed electrician.
How the job is done
- 1
Plan placement and choose the fixtures
We decide between LED strips for even coverage or puck lights for accents, and position them toward the front underside of the cabinets so light hits the counter.
- 2
Pick plug-in or hardwired and kill power if needed
For hardwired runs we shut off and test the circuit first; for plug-in systems we plan the route to an existing outlet so no wiring is exposed.
- 3
Mount the lights
Fixtures are secured to the underside of the cabinets, kept straight and consistent, and spaced so there are no dark gaps between them.
- 4
Route and hide the wiring
Wires and connectors are tucked along the back lip of the cabinets and through small holes where needed so nothing dangles into view.
- 5
Connect power and controls
Lights are linked together and connected to a switch, dimmer, or a discreet plug-in transformer, and any low-voltage driver is placed where it is accessible but hidden.
- 6
Test and fine-tune
We power up the lights, check for even brightness and matching color, and adjust the dimmer and placement until the counter is lit cleanly with no glare.
What a pro checks
- Mounting lights near the front edge of the cabinet lights the countertop; mounting them at the back mostly lights the backsplash.
- Matching color temperature to the rest of the kitchen keeps the new lights from looking out of place.
- Hardwired installs give a cord-free look but may involve a new switch leg or circuit, which can require a licensed electrician.
- Low-voltage LED systems need a correctly sized driver or transformer placed where it stays cool and reachable.
- Linkable LED strips with a dimmer let you set bright task light for cooking and softer light for evenings — the AZ Smart Fix team can wire this in cleanly.

Frequently asked questions
Plug-in or hardwired — which is better?
Plug-in is faster, cheaper to install, and avoids opening walls, but you see a cord to an outlet. Hardwired looks seamless and runs to a wall switch, but it is a bigger job.
Are LED strips or puck lights better under cabinets?
Strips give smooth, even coverage across the counter, while pucks create brighter pools with gaps between them. Most kitchens look best with continuous strip or tape lighting.
Can under-cabinet lights be dimmed?
Yes, with a compatible dimmer and dimmable LEDs. We match the two so you get smooth control without flicker or buzz.
Will this require an electrician?
Plug-in systems usually do not. A hardwired setup that adds a new switch or circuit may need a licensed electrician, and we will tell you up front which path your kitchen calls for.
