Undercabinet lighting is one of the highest-impact, lowest-disruption upgrades you can make to a kitchen. It's also one of the most commonly done wrong — visible cords, mismatched color temperatures, dim spots where you actually need light. Here's how to get it right.
Why Homeowners Add Undercabinet Lighting
Overhead kitchen lighting casts shadows exactly where you're working — over the counter, right where your hands and the cutting board are. Undercabinet lighting solves that directly, and it does double duty: real task lighting while you're cooking, and a warm ambient glow the rest of the time. It's also one of the more noticeable upgrades to buyers when it comes time to sell — clean, layered kitchen lighting reads as a finished, cared-for space.
LED Strip vs. Puck Lights vs. Linear Fixtures
- LED strip lighting — continuous, even light along the full run of cabinets. The most popular choice for a clean, modern look with no visible hot spots.
- Puck lights — individual round fixtures, spaced along the cabinet. Good for accent lighting or open shelving, but can create visible bright spots with shadows between them for task lighting.
- Linear bar fixtures — rigid aluminum-housed LED bars. Very clean look, good heat dissipation, slightly more visible than a low-profile strip.
For most kitchens, we recommend LED strip in an aluminum channel — it diffuses the light evenly and protects the strip itself.
Plug-In vs. Hardwired: What's the Difference
This is the decision that actually matters most:
- Plug-in kits are DIY-friendly and cheap, but come with a visible transformer/driver box and a cord that has to run somewhere — usually down the side of a cabinet or through a drilled hole, and it plugs into a nearby outlet that's now dedicated to the lights.
- Hardwired lighting is wired directly into your home's electrical system, with the driver hidden inside the cabinet and no visible cords anywhere. It also lets us tie the lights into a wall switch or dimmer — flip a switch instead of reaching under the cabinet.
If you want it to look like it was always part of the kitchen, hardwired is the only way to get there.
What Does Professional Undercabinet Lighting Installation Cost?
| Scope | Typical Range |
|---|---|
| Single run, existing switch/circuit nearby | $300 – $600 |
| Full kitchen, new switch/dimmer circuit | $600 – $1,200 |
| Add smart/app-controlled dimming | +$150 – $350 |
Cost depends on total cabinet run length, whether we can tie into an existing switch leg or need to run a new one, and whether you want dimming or smart control added.
Dimmers, Switches, and Smart Control Options
Most homeowners tie undercabinet lighting into a dedicated wall switch — sometimes the same switch as the overhead lights, sometimes its own. Dimmable LED drivers are standard at this point and barely add to the cost. If you want app or voice control, we can wire in a smart switch or dimmer instead of a standard one for a modest upcharge.
What to Expect During Installation
- Quick site visit or photos — we look at your cabinet layout and existing switch/outlet locations.
- Quote — firm price based on total run length and whether new wiring is needed.
- Installation — most kitchens are done in a few hours, with minimal disruption since we're working inside cabinets and behind a small section of wall or trim.
