Under-cabinet lighting: types, placement and wiring options

Table of Contents

Share:

Under cabinet lighting costs an average of $400, and most homeowners spend $200 to $800, according to Angi’s May 2026 cost data. The light is the easy part. The decision that moves the price is whether the fixtures plug into an outlet or are wired into the wall, and that choice belongs in the design phase, before the backsplash goes up.

This guide compares the three fixture types, explains plug-in versus hardwired in plain terms and covers the California control rules that catch people out. It also gives placement, brightness and Kelvin numbers that fit our guide to layered kitchen lighting. All prices are national. This guide found no independent county-level data for Marin, Sonoma or Napa, so none appears here.

Under cabinet lighting types compared

Three formats cover almost every kitchen that uses LED under cabinet lighting: light bars, LED tape and puck lights. They differ in how even the light looks on the counter, how much space they need under the cabinet and what they cost.

TypeHow the light looksAngi 2026 costSize, per PROLIGHTING
Light barRigid, even line$30 to $60 per bar6 to 48 inches long
LED tapeThin, continuous, turns corners$20 to $50 per linear foot16-foot reels
PuckRound, focused pools$10 to $30 each1 to 4 inches across

PROLIGHTING’s guide says light bars sit lower than traditional linear fixtures but higher than tape. It describes LED tape as the most flexible format and says puck lights give a focused, spotlight look. That makes pucks a better fit for display shelves than for a prep counter, which is a design judgment and not a claim from the source.

Polished counters add a wrinkle. Flexfire LEDs, a strip maker, says a shiny or reflective top may call for frosted diffusers to soften glare and prevent visible spotting. If you are still choosing a surface, our guide to kitchen countertop materials puts the options side by side. For the rest of the room, see our kitchen lighting design tips.

Plug-in or hardwired, the real decision

How plug-in and hardwired systems differ

Plug-in under cabinet lighting runs off an outlet, and hardwired under cabinet lighting runs off a 120-volt feed inside the wall. PROLIGHTING calls plug-in the simplest route and a smart choice for anyone without electrical knowledge, though it needs an outlet within reach. Hardwired fixtures give a clean, cord-free look and can link end to end once the first connection is made, but the same guide says to leave that work to an electrician.

Money follows the same split. Angi says plug-in systems are easier to install and cost less, while hardwired options need professional help and more wiring. Custom hardwired systems can pass $1,500. Electricians charge $50 to $120 an hour, and electrician labor often makes up 40 to 60 percent of the total.

Planning wiring before the backsplash

Timing is where a remodel changes the math. During demolition the walls are open, and running one more feed costs little because the electrician is already there. After the backsplash is set, the same feed means opening finished surfaces. That is a design inference and not a number from a source, but it is the reason lighting belongs on the plan early.

If a full gut is not planned, plug-in is a sensible choice. Our guide to planning a modern kitchen remodel without overspending and our tips to help you save when remodeling explain where lighting sits in a tight budget.

California rules and permits for under cabinet lighting

Permanently installed lighting and controls

The state energy code shapes hardwired plans. The California Energy Commission’s 2022 Residential Compliance Manual says all permanently installed luminaires must be classed as high efficacy. It also says kitchens need readily accessible wall-mounted dimming controls that let you adjust the lighting up and down.

One rule is about switching. The manual says undercabinet lighting must be controlled separately from ceiling lighting, so one can be on while the other is off. In plain terms, the under-cabinet run needs its own switch or dimmer. Plan that control location before the drywall closes.

For a remodel, the manual says new or altered lighting must meet the rules, while existing lighting you do not touch may stay as is. So a kitchen that keeps its old fixtures gets different treatment than one that is replanned from scratch. The manual’s wording covers permanently installed luminaires, so ask your building department how it treats a plug-in unit.

Local permit requirements

Permits are a local question. Model-code language, as quoted on the City of Mountain View’s permit page, exempts minor electrical repair work such as replacing lamps or plugging approved portable equipment into approved receptacles. New wiring and new fixtures fall outside that wording. Marin, Sonoma and Napa counties and their cities publish their own rules, so confirm with your local building department before you cut a hole. A kitchen and bath designer can flag these items early.

Placement on the cabinet underside

Two published guides disagree on where under cabinet lighting should sit, and the disagreement is worth knowing. Flexfire says that for task lighting the strip should sit toward the middle of the front edge so the counter gets as much light as possible. BuyRite Electric’s placement guide says to mount LEDs one to two inches behind the cabinet front so your body does not cast a shadow on the work surface.

Both agree on one point. Do not push the light against the wall. Flexfire notes a strip has a 120-degree beam, and a strip jammed to the back splashes light onto the wall and wastes it on the counter.

BuyRite also says to hide the diodes behind a diffuser, valance or shield, and cites a target of 300 to 500 lux on work surfaces. That is a vendor target, not a code number. The NKBA’s Kitchen Planning Guidelines are less specific. They recommend that every work surface be lit by appropriate task lighting on top of the general lighting the code requires.

The practical fix is a quick mock-up. Tape a strip in two positions and stand at the counter at night with your normal prep tools. To plan around how you cook, start with our smart kitchen design tips and our guide to maximizing kitchen space, which cover the work zones the light has to serve.

Brightness, Kelvin and CRI for LED under cabinet lighting

Brightness and dimming

Brightness for strips is counted in lumens per foot. Flexfire’s guide sorts it by purpose, and the under-cabinet range for work light is the middle row.

PurposeLumens per foot (Flexfire)
Principal lighting500 to 1,000
Task or accent lighting200 to 500
Mood or low accent lighting80 to 200

Choose strips that dim down rather than fixtures sized to the minimum. Flexfire says its strips dim to 1 percent, so one install can serve prep light at full output and a night glow at low output.

Kelvin and matching the ceiling lights

Color temperature matters as much. The U.S. Department of Energy’s lighting guidance lists 2,700K as warm, 3,000K as soft, 3,500K as neutral and 4,100K as cool. PROLIGHTING recommends 3000K to 4000K for kitchens, while Flexfire extends its range to 5000K. The common band is 3000K to 4000K.

Our layered lighting guide says similar temperatures across layers keep a room cohesive, but it gives no Kelvin numbers. The simple rule is to match the ceiling layer. If your recessed lights read 3000K, buy 3000K strips. Mixing 2700K above with 4000K below can leave the counter looking uneven.

CRI and color accuracy

Color accuracy is the third number for any under-cabinet lighting spec. PROLIGHTING says a CRI of 85 is adequate and 90 or higher gives better kitchen color. The DOE says ENERGY STAR bulbs must reach CRI 80. A higher CRI means truer color on food, which is why it deserves a line on your spec sheet. For a spare, quiet look, see our guide to minimalist kitchen design.

Power supplies, voltage and run length

Drivers and strip voltage

LED under cabinet lighting needs a low-voltage driver, also called a power supply, that turns wall power into low voltage. Flexfire says 24-volt strips are the most popular for under-cabinet use. The 24-volt version lets you place the driver farther away, even under the sink. A 12-volt strip works on shorter segments.

Run length and voltage drop

Run length matters because voltage drops as current travels. HitLights, another strip maker, gives about 16 feet as the longest 12-volt run and about 32 feet for 24-volt, without extra feeds. Many kitchen runs fall under that, but a long wall with a corner turn adds up fast. Uneven brightness at the far end is the usual symptom.

Driver capacity, dimmers and access

Size the driver with spare capacity. Flexfire’s rule is to multiply watts per foot by total feet, then add 20 percent so the supply is not overloaded. Dimming compatibility adds a check. BuyRite notes that 0-10V dimming needs separate signal wires alongside power, and it recommends high-frequency dimming drivers above 2kHz. Ask the supplier to confirm that the dimmer and driver are a matched pair.

Put the driver where someone can reach it. A hidden box that cannot be reached is a service call waiting to happen. For other planning errors worth avoiding, see our list of kitchen layout mistakes.

Cost drivers for under cabinet lighting

Angi’s 2026 figures give a useful frame for under cabinet lighting. A 10-foot run of LED tape at $20 to $50 per foot comes to about $200 to $500 in fixture cost, by simple arithmetic on Angi’s per-foot range. The fixtures are the cheap side of the project. Wiring, a new switch, patching and paint are what push the invoice up.

Labor deserves a second look. Angi puts electrician rates at $50 to $120 an hour and says labor can be 40 to 60 percent of the total. A plug-in bar avoids most of that, which helps explain the spread between $200 and $1,500 in Angi’s figures. The top number is for custom hardwired work, so treat it as an upper limit.

Projects Within Reach has not published lighting prices, and this guide found no second dated source to cross-check Angi. Treat the numbers as a starting point and expect real quotes to differ. Cabinet color also changes how a strip reads on the counter, so our overview of top kitchen cabinet trends is worth a look before you pick a finish.

Choosing under cabinet lighting by household

Lighting an existing kitchen

If you are not remodeling, choose plug-in bars or tape with a plug-in driver and a dimmer on the cord. You get the work light for a few hundred dollars and no wall repair. If you cook a lot and your counters are dark or glossy, add frosted diffusers and aim for 90-plus CRI.

Lighting during a remodel

If you are remodeling now, ask for a hardwired run on its own dimmer, with the driver in a reachable spot. That is the version that keeps the counter clear of cords and meets the separate-control rule. I tell clients to settle the switch location before cabinets are ordered, because the cabinet maker needs to know where the wiring path runs.

Island and breakfast-area work zones

If you have an island or a breakfast area, light the work surface, not the seating. For island and nook layouts, see our guide to kitchen islands that steal the spotlight and our breakfast nook ideas. Each separate zone can take its own light.

FAQ

Lifespan of LED strips and bars

The DOE’s FEMP page lists a rated lifetime of 25,000 hours for LEDs, based on ENERGY STAR minimums, which is about 22 years at three hours a day. That figure is for LED bulbs, so check the maker’s rating for the exact strip, bar or driver you buy.

Dimmer compatibility and flicker

Flexfire says its strips dim down to 1 percent. BuyRite adds that 0-10V systems need separate signal wires and that drivers above 2kHz suit high-frequency dimming. Flicker often points to a mismatched pair, so buy the dimmer and driver together.

Battery-powered options

Angi says plug-in or battery-powered lights avoid electrical work. They suit a short run with no outlet nearby, though this guide found no independent data on brightness or runtime. Look for a rechargeable model with a dimmer and treat it as a stopgap.
