Walk into most Chicago-area kitchens built before 2000 and you find the same setup: one fixture in the middle of the ceiling. Turn it on, stand at the counter, and your own shoulders cast a shadow over the exact spot where you are chopping. We install countertops for a living, and it pains us to watch good stone spend its life in shadow. No single fixture can light a room and its work surfaces at the same time — which is why designers plan kitchen light in three layers, each with its own job and its own switch.

Layer 1: Ambient — light to move by

Ambient light is the soft, general illumination that fills the room. In most kitchens that means recessed downlights, a central fixture, or both. Two placement rules do most of the work:

Space recessed cans about half the ceiling height apart. Under an 8-foot ceiling, that is roughly 4 feet between cans; under 10 feet, about 5 feet. The light cones overlap and the room reads evenly lit.
Keep cans a few inches inside the countertop edge line, not directly over where you stand, so your head does not shadow the counter.

Ambient light alone is where most older kitchens stop — and why they feel dim even with a bright bulb.

Layer 2: Task — light to work by

Task lighting is focused light on the surfaces where knives, heat, and water live. The workhorses:

Under-cabinet lights are the single highest-value upgrade in kitchen lighting, and the best friend your new countertop will ever have. Placement matters more than brand: mount them within about 1-3 inches of the cabinet's front rail, aimed down at the counter, and hide them behind the face frame or a light-rail molding. Mounted at the back of the cabinet, they light your backsplash and leave the cutting board in shadow.

Choose the fixture type by the job. Continuous LED tape or linkable linear bars give one even line of light with no dead spots — right for any run where you actually prep. Puck lights throw circles of light with dim gaps between them, and every puck reflects as a bright dot in polished stone — we see those little constellations in every polished slab we deliver under them; save pucks for glass-door cabinets and display shelves.

Pendants put task light on islands and sinks. Hang them so the bottom sits 30-36 inches above the counter (closer to 30 under 8-foot ceilings). For two pendants, set each center in from the island ends by the island length divided by 3 to 4, keep at least 6 inches of end clearance, and 24-30 inches between centers. Two larger pendants usually beat three small ones on islands up to about 10 feet; past that, consider a single linear fixture.

Layer 3: Accent — light for depth

Accent light is optional but transforms how a kitchen feels after dinner: toe-kick strips, interior cabinet lighting, a glow above the crown molding. Keep accent zones dimmer than task zones and on their own switch, so the kitchen can idle at a low, warm level in the evening.

Put every layer on its own dimmer

The cheapest luxury in lighting is control. Ambient, task, and accent should each dim independently — bright for cooking, low for entertaining, one zone on for the midnight glass of water. In Illinois there is also a code angle: under the state's 2021 energy code, permanently installed fixtures must use high-efficacy (LED) sources and be controlled by a dimmer, occupancy sensor, or built-in control. Dimmable LED everywhere satisfies the inspector and the design at once. Outside Illinois, code editions differ — ask your local building department what applies.

What it costs

Under-cabinet lighting, the layer most kitchens are missing, is not a big-ticket item. As of late-2025 market pricing, a typical project runs $200-$800 installed, with a median around $400. Plug-in kits cost $15-$70 and skip the electrician entirely; hardwired systems add labor that can average roughly $200 per fixture. Custom multi-zone systems with drivers and smart controls can pass $1,500.

The smartest scheduling move — and the one we flag for every countertop customer: hardwire task lighting while your backsplash is off during a countertop or tile replacement. The wall is already open, so the wiring costs a fraction of a standalone retrofit. We watch this window close unused every week; do not let yours.

Where to spend first

Under-cabinet task lighting — the biggest daily-use payoff per dollar.
Dimmers on whatever you already own.
Pendants over the island, sized and hung to the numbers above.
Accent zones last — they are polish, not function.

Layered light will not make a small kitchen bigger or an old countertop new. What it does is let one room do every job you ask of it — prep station at 5:30, dinner table at 7, night light at midnight — without a remodel-sized budget.
