If you chop vegetables in your own shadow, read recipes under a single dome light, or still have a fluorescent box humming over the counter, the lighting is working against you. Better light is one of the most noticeable changes a kitchen remodel can make. It is also the part where it helps to know which updates are simple fixture swaps and which mean new wiring.

Layers of light

A well-lit kitchen draws on several sources, each with a different job:

• Ambient light fills the room, usually from recessed lights or a ceiling fixture.

• Task light lands on the work surfaces: under-cabinet lights over the counters, a light over the sink, pendants over an island.

• Accent light adds depth, such as lighting inside glass-front cabinets or above the uppers.

Daylight is a layer too: a kitchen with a big west window may need very little light at noon and a lot after dark. Over the sink, a recessed light or small pendant lights the basin where you rinse produce and scrub pans, and the light built into a range hood covers the cooktop. A single ceiling fixture, by contrast, puts your body between the light and the counter every time you face the wall. Layering fixes that, and our kitchen lighting plan basics walk through laying out each layer.

Recessed lights, under-cabinet strips and pendants

Recessed lights

Recessed lights are placed over the front edge of the counters rather than down the middle of the room, so light falls where your hands are. Low-profile LED fixtures fit shallow ceilings, and California’s energy code sets rules for recessed downlights, including airtight housings and no screw-in bulb sockets.

Under-cabinet lighting

Nothing on the ceiling does as much for counter work. LED strips or bars mounted toward the front of the cabinet throw light across the whole counter; over a polished counter, mounting them toward the back and aiming at the backsplash cuts glare. Hardwired fixtures with hidden wiring look cleaner than plug-in strips.

Pendants

Pendants over an island are usually hung about 30 to 36 inches above the counter, high enough to see under and low enough to light the work. Two or three is typical, depending on the island’s length. Clear glass shows the bulb and every bit of dust, while opaque or frosted shades direct light down and hide both.

Inside the cabinets

Lights inside glass-front uppers or drawers are a finishing touch rather than a necessity. Behind solid doors, California’s energy code calls for them to switch off when the door or drawer closes, so they are planned along with the cabinets.

Color, brightness and controls

Choose one color temperature and keep it consistent. Warm light around 2700K to 3000K feels like the rest of a home, while 3500K to 4000K reads crisper and cooler. Mixing them makes some fixtures look yellow and others blue. A color rendering index of 90 or higher makes food, wood and paint colors look true.

Controls matter as much as fixtures. When lighting is replaced or added under a permit, California’s energy code generally calls for dimmers on kitchen lighting and separate switching for under-cabinet lights. Dimmers also have to match the fixtures, since an LED light on an incompatible dimmer can flicker or hum at low settings. Grouping lights so you can run task lighting alone, or dim the room in the evening, lets one kitchen work for cooking and for sitting.

Fixture swaps versus new wiring

Replacing a light with a new one in the same spot, on the same circuit, is straightforward fixture work: a new ceiling fixture, a pendant on an existing box, or an LED fixture in place of an old fluorescent one. Adding recessed lights where there were none, wiring under-cabinet lights, hanging pendants over a new island, or adding circuits is different. That is licensed electrical work, done by licensed electrical trades we coordinate, and whether it needs a permit is confirmed during the in-home consultation. Smart switches and dimmers can often replace existing switches without new wiring, though many need a neutral wire that some older switch boxes lack.

Older homes raise their own questions. About half of Fresno’s homes were built before 1980, according to Census estimates, and kitchens from those decades were often built around a single ceiling light. Whether the existing wiring can support more lighting is evaluated during the consultation rather than assumed, and any panel or circuit work is for licensed electricians. Older wiring is one of several issues covered in our guide to remodeling older Fresno homes.

Lighting in the estimator and the investment

Lighting shows up in two places in the kitchen estimator. The plumbing and electrical step offers three answers: standard updates, where outlets and lighting stay put; minor changes, where a few outlets, lights or fixtures are moved or added; and major changes, where wiring is relocated more broadly. The finish level question, from standard to high-end, reflects the fixtures and details you have in mind.

If your lighting plan adds new wiring, choose minor or major changes so the range reflects it. Because lighting is usually one part of a larger kitchen project, the useful numbers are the whole-kitchen planning bands: most projects begin around $25,000, a typical kitchen remodel sits near $40,000, and remodels that move walls or choose premium selections run $50,000 to $60,000.

Plan lighting before the walls close

Fixtures go up last, but lighting is decided early. Wiring for recessed lights, pendants and under-cabinet strips has to run while ceilings and walls are open, before cabinets, drywall patches and backsplash tile close everything in. The lighting plan is confirmed alongside the cabinet plan, so under-cabinet wiring lands where the cabinet bottoms will be. If you are replacing cabinets or adding an island or new layout, that is the time to plan lighting with it, because adding wiring after the tile is up means cutting into finished work.
