Under-Cabinet Lighting (plug-in)
The kitchen workspace that has been dark since the contractor moved out — no under-cabinet lighting at all, the counter lit only by the overhead can lights that throw shadows from the upper cabinets onto every cutting board. The plug-in LED bars from the big-box store that have been sitting in the box for six months because the adhesive tape never stuck right and the cord routing was vague. The puck lights that the prior installer left dangling from a cord visibly down the side of the upper cabinet to the counter outlet. Plug-in under-cabinet lighting is the trade for the cleanest cord-routed fix to a dark counter — LED light bars, puck lights, or low-voltage ribbon strips mounted under the upper cabinets and plugged into an existing kitchen outlet. Handyman scope because the install runs entirely on an existing receptacle with no new circuit, no new junction box, no concealed in-wall wiring. From $250 for a single short LED bar to $700 for a multi-fixture install across a full upper-cabinet run with cord-channel coordination. Same-day install in 2 to 4 hours per kitchen.

What Does a Plug-In Under-Cabinet Lighting Install Include?
A plug-in under-cabinet lighting install covers fixture layout against the cabinet run, mounting (adhesive-back tape or screw-mount to the underside of the cabinet using cabinet-safe short screws that do not penetrate the cabinet face), cord routing in cord channels (Wiremold CordMate, Legrand Wiremold, or PVC raceway) along the back undersides of the cabinets to an existing kitchen outlet, in-line connector or daisy-chain wiring between fixtures, dimmer or remote-control setup where the fixture supports it, and function test of every fixture before sign-off. Handyman scope because the install runs entirely on an existing receptacle with no new circuit, no new junction box, no concealed in-wall wiring. From $250 for a single short LED bar to $700 for a multi-fixture install across a full upper-cabinet run. Most installs finish in 2 to 4 hours per kitchen.
LED Light Bar Install (Single or Daisy-Chained)
Linear LED light bars — typically 12, 18, 24, or 36 inches long, in warm-white, neutral-white, or cool-white — mounted under the upper cabinets in single fixtures or daisy-chained across a multi-cabinet run. Brands include Phillips Hue Lightstrip Plus, GE Enbrighten LED Plus, Honeywell, Utilitech. Adhesive-back mount or screw-mount to the underside of the cabinet. From $250 labor for a single short bar to $500 for a multi-cabinet daisy-chain run.
Puck Light Install
Small disc-shaped fixtures (typically 2-1/2 to 3-1/2 inches in diameter) mounted directly to the underside of the cabinet — 2 to 5 pucks per cabinet run depending on the desired spacing and brightness. Brands include Westek, GE, Lightkiwi, Power Pro. Adhesive-back or screw-mount. Wired to a single power supply that plugs into the existing outlet. From $300 labor for a small puck install to $500 for a multi-cabinet run.
Low-Voltage Ribbon Strip Install
Flexible LED ribbon strips — typically 8 to 16 feet per kit, in cuttable lengths — mounted with adhesive-back tape under the cabinet front lip or in a small aluminum channel for diffusion. Brands include Govee, Phillips Hue Lightstrip Plus, GE Cync. The most-discreet under-cabinet lighting option because the fixture itself is nearly invisible from any normal viewing angle. From $350 labor for a small ribbon install to $700 for a full multi-cabinet ribbon run with diffuser channels.
Cord Channel and Routing
Every plug-in install includes cord channels (Wiremold CordMate II or equivalent paintable plastic channel) to route the cord cleanly along the back underside of the cabinets to the existing outlet — never a cord running visibly down the side of the cabinet. Channels paint to match the cabinet color when needed. The detail that makes a plug-in lighting install read as integrated rather than DIY-improvised.
Dimmer and Smart-Control Setup
Where the fixture supports it, dimmer control via the included in-line dimmer, the included remote control, or the smart-home integration (Phillips Hue Bridge, Govee Home app, Lutron Caseta compatible models). Setup with the homeowner on the final visit so the dimmer scenes and the on-off schedule match the actual kitchen-use pattern.
How a Plug-In Under-Cabinet Lighting Install Works
Six sequential steps from on-arrival layout through mounting, cord routing, and function test — the actual sequence on every Handis plug-in under-cabinet lighting install.
Lay Out Fixture Positions Against the Cabinet Run
Measure the upper-cabinet run from end to end. Lay out fixture positions for even light distribution — LED bars typically 1 to 2 inches back from the cabinet front, puck lights centered on the cabinet width, ribbon strips against the cabinet front lip for the most-forward task lighting. Identify the existing kitchen outlet that the install will plug into and plan the cord route from each fixture to the outlet.
Confirm Outlet Power and Switch Configuration
Verify the existing kitchen outlet has power. Confirm whether the outlet is on a switched circuit (so the wall switch controls the lighting) or an unswitched outlet (so the lighting controls from the fixture's own switch, remote, or smart-home app). Plan the on-off path with the homeowner — wall switch, in-line cord switch, remote, or smart-home app.
Install Cord Channels Along the Back Cabinet Underside
Mount Wiremold CordMate II or equivalent paintable cord channels along the back underside of the upper cabinets, running from each fixture location to the kitchen outlet. Channels mount with the included adhesive-back tape on clean and dust-free cabinet surfaces. Channels paint to match the cabinet color when needed (typically on white or off-white cabinets; less critical on dark cabinets where the channel reads as shadow).
Mount the Fixtures with Adhesive or Cabinet-Safe Screws
For adhesive-back fixtures (most LED bars, puck lights, ribbon strips), clean the cabinet underside with isopropyl alcohol, press the fixture into position, hold for 30 seconds to bond the adhesive. For screw-mount fixtures, drill pilot holes with a cabinet-safe short bit (3/4-inch maximum depth so the screw never penetrates the cabinet face), drive cabinet-safe short screws (3/4-inch or shorter). Align fixtures with the layout marks.
Route Cords Through Channels, Daisy-Chain Connectors
Route the cord from each fixture into the cord channel and run to the next fixture or to the outlet. Daisy-chain in-line connectors (most LED bars include them) connect multiple fixtures to a single power tap. Snap the channel covers closed over the cord run. Final cord visible only at the plug end where it terminates at the outlet.
Plug In, Test Every Fixture, Set Dimmer or Remote
Plug the power supply into the existing kitchen outlet. Test every fixture under power — full brightness, dimmer or remote function (where supported), and the on-off path agreed with the homeowner. Set the smart-home pairing where the fixture supports it (Phillips Hue Bridge, Govee app, Lutron Caseta). Final walkthrough with the homeowner to confirm the lighting reads against the counter as expected.
Plug-In Under-Cabinet Lighting Pricing
Final pricing is labor plus the fixture cost (owner-supplied is fine; we can also source LED bars, puck lights, and ribbon strips from major brand lines). Cord channels and connectors included in every install. Hardwired upgrades, new circuits, new switches, or dimmer installs in the wall route to a licensed Washington L&I electrician as a separate scope (see Hardwired Under-Cabinet Lighting).

Why Handis for Plug-In Under-Cabinet Lighting
The most-common failure on a DIY plug-in under-cabinet lighting install is the cord that ends up running visibly down the side of the upper cabinet to the counter outlet — every kitchen reads it as a half-finished install from across the room. The second-most-common is the adhesive-back LED bar that falls off the cabinet underside three weeks later because the install was done on a greasy or dust-covered cabinet surface that the adhesive never bonded to. The third is the multi-fixture install where the daisy-chain connectors were not planned around an existing outlet position, leaving exposed in-line connectors in the middle of the cabinet run instead of cleanly inside the cord channel. Handis runs the cord-channel layout, the adhesive-prep wipe-down with isopropyl alcohol, and the daisy-chain plan before the first fixture mounts — three small disciplines that turn a plug-in install into an integrated finish instead of a DIY improvisation.
Cord channels on every install — never a visible cord
Every plug-in install includes Wiremold CordMate II or equivalent paintable cord channels to route the cord cleanly along the back underside of the upper cabinets to the existing outlet. Channels paint to match the cabinet color where needed. No cord running visibly down the side of the cabinet to the counter outlet — the detail that makes a plug-in install read as integrated rather than DIY.
Adhesive prep with isopropyl alcohol before the bond
Adhesive-back LED bars, puck lights, and ribbon strips bond properly only on a clean, dust-free, grease-free surface. We wipe the cabinet underside with 70-percent isopropyl alcohol on a clean rag before pressing the fixture into position, then hold for 30 seconds to set the bond. The adhesive failure most DIY installs hit traces back to the cabinet underside that was never cleaned.
Cabinet-safe screws on screw-mount fixtures
For screw-mount fixtures (most longer LED bars and puck installs), pilot holes are drilled with a 3/4-inch maximum depth bit so the screw never penetrates the cabinet face, and screws are 3/4-inch or shorter to stay safely inside the cabinet bottom. The detail that prevents a screw tip showing on the inside of the upper cabinet — a small visible damage that every kitchen owner notices.
Daisy-chain plan against the outlet position
Multi-fixture daisy-chain runs are planned around the existing outlet position so the in-line connectors land cleanly inside the cord channel and the power tap connects directly to the outlet. The wrong plan leaves exposed connectors in the middle of the cabinet run; the right plan keeps the entire cord path concealed in the channel.
Dimmer and smart-home setup walkthrough on the final visit
Where the fixture supports dimmer or smart-home integration (Phillips Hue, Govee, Lutron Caseta), we set up the pairing with the homeowner on the final visit so the lighting scenes and on-off schedules match the actual kitchen-use pattern. The setup walkthrough is included in the install scope — not an upsell.
Insured, background-checked, 30-day workmanship guarantee
Every Handis tech carries liability insurance and has cleared a background screening. 30-day workmanship guarantee on every plug-in under-cabinet lighting install — if a fixture comes loose from the cabinet underside, a cord channel separates from the cabinet, a daisy-chain connector loosens, or a fixture stops working within 30 days because of our install, we come back and fix it at no extra charge. The guarantee covers our install; it does not cover the LED fixture itself failing months later (a known wear part on a separate lifecycle), damage from owner-applied cleaning chemicals on the adhesive bond, or smart-home integration issues that trace to the homeowner's app, account, or hub configuration.

Customer Reviews
Plug-in under-cabinet lighting reviews from real Handis customers.
Plug-in LED light bars under the upper cabinets across about 8 linear feet of our kitchen. Three sections of cabinet. The tech ran the cord channels along the back undersides of the cabinets so no cord shows from the counter side. Plugged into an existing outlet behind the cabinet at the end of the run. Looks like a proper install, not a DIY job.
Puck lights under our upper cabinets with the wireless remote that came with the kit. Tech mounted three pucks per cabinet over about 6 linear feet, wired everything to one power supply at an outlet behind the cabinet, paired the remote with the homeowner walkthrough at the end. The kitchen counter went from shadowed to evenly lit.
Low-voltage ribbon strips in aluminum diffuser channels under the upper cabinets. The diffusers softened the LED light so there are no hot spots on the counter. About 10 feet of run, daisy-chained to one power supply. The strips themselves are invisible from any normal viewing angle. Done in 4 hours.
I bought a set of GE Enbrighten LED bars and had them sitting in the box for six months because I could not figure out the cord routing. Handis installed the whole set in one visit — cord channels along the back undersides, daisy-chain connectors hidden inside the channels, plug at the existing outlet behind the corner cabinet. Should have called them six months ago.
Phillips Hue Lightstrip Plus under our upper cabinets, plus the Hue Bridge for smart-home integration. Tech installed the strip, set up the Hue Bridge with our home Wi-Fi, walked us through the app scenes (full-bright for cooking, dim warm-white for evening). The strip reads as part of the cabinet now instead of a fixture stuck on.
