Planning Kitchen Lighting in an Older Riverside House
Why Does Kitchen Lighting Go Wrong So Often in Older Riverside Homes?
Many kitchens in the older houses around Downtown, the Eastside, and Casa Blanca were lit with one ceiling fixture in the middle of the room and a bulb over the sink. That worked when the kitchen was a small room with a single cook. Once the cabinets are replaced and the countertop gets longer, the same fixture throws shadows exactly where the knife is working. Lighting is planned in layers, and a remodel is the only time the ceiling and walls are open enough to do it cleanly.
The questions below come up on nearly every kitchen job, and the answers shape how the electrician, the cabinet installer, and the plasterer sequence their work.
What Are the Three Layers of Kitchen Light?
Crews talk about ambient, task, and accent light. Ambient light fills the room evenly and usually comes from ceiling fixtures or recessed cans. Task light sits close to the work: under the upper cabinets, over the sink, above the range. Accent light is optional and picks out glass doors, an open shelf, or the inside of a cabinet.
The task layer does most of the useful work. A countertop in the shadow of an upper cabinet is the dimmest surface in the room, and a strip light fixed under the cabinet edge fixes that at the source. Ambient light alone makes the room bright but leaves the work surface dark.
Where Do Recessed Lights Go in a Plaster Ceiling?
Recessed cans are the usual ambient choice, and they are harder to install in an old house than in a new one. A plaster and lath ceiling is heavy and brittle. Cutting a round hole cracks the surrounding plaster unless the crew scores the circle first and supports it from above. Beyond the plaster, the cavity above the ceiling may hold old knob and tube wiring, fiber insulation, and in some Queen Anne houses the remains of a gas lighting line.
Mid-century tract homes are easier. A drywall ceiling takes cans readily, though the attic above can be shallow, and a can that is not rated for insulation contact cannot sit under blown insulation. In a hot attic the heat trapped around a can shortens the life of the fixture, so a rated unit with a sealed housing is the right pick.
Spacing follows the work, not a grid. Cans are placed over the front edge of the countertop and the sink, not the center of the floor, so the cook does not stand in their own shadow.
How Does Natural Light Change the Plan?
Riverside gets strong sun for most of the year, and a kitchen window can flood a room in the afternoon. That helps in winter and works against the air conditioning in summer. A west window above the sink often needs a shade or an awning, and the lighting plan should assume the room is bright in the day and artificial light is mainly an evening matter.
Glare is the usual problem. Polished stone on a countertop and a glossy tile backsplash bounce window light straight back at the eye. A honed or matte surface reduces it, and so does placing the sink and prep area off to the side of the window, not in line with it. The designer looks at where the sun lands at four in the afternoon in July, not just at noon.
Which Kind of Under-Cabinet Light Is Worth Using?
Under-cabinet lights come in rigid bars, flexible strips, and round pucks. Each has a character.
- Bars are even and sturdy, and the best choice for a long run of countertop.
- Strips are thin and can follow a curve or a corner, but they need a diffuser, or the individual points of light show as bright dots on a glossy surface.
- Pucks are quick to install and leave a scalloped pattern of light and dark along the countertop.
Whichever type goes in, it should sit at the front of the cabinet, close to the edge, so the light lands on the work surface and not on the backsplash. A fixture pushed against the wall lights the wall and leaves the countertop dim. The wiring comes from a switched circuit, and in a remodel the electrician runs it through the wall before the drywall is closed, since fishing a wire behind finished tile is nearly impossible.
What Color of Light Looks Right?
Bulbs and strips are sold by color temperature, from a warm yellow to a cool blue-white. A kitchen usually wants something between the two: warm enough to flatter wood cabinets and skin, clean enough to judge the color of food. The bigger rule is consistency. Mixing warm cans with cool strips makes the room look patched together, and a mismatch on a stone countertop shows right away. The crew picks one temperature for the whole room and tests it against the actual cabinet and counter samples before ordering.
Dimmers belong on the ambient layer. A kitchen that is a workroom at six and a dining room at eight should not have only one brightness. Dimmers must match the bulbs, since not every light dims smoothly, and a mismatch causes buzzing or flicker.
Do Lights Need Their Own Circuit?
Lighting normally shares a general circuit with the dining area or nearby rooms, and the outlets above the countertop run on separate small-appliance circuits. Heavy loads, such as the range, the dishwasher, the disposal, and the microwave, get their own. Adding a dozen recessed cans and a run of strip light to an old panel can push a circuit past its limit, and older houses often have a panel that is already full.
The electrician adds up the load before cutting anything. In an older Riverside house, that count may show the panel needs an upgrade or a subpanel before the new kitchen can be wired. Lighting changes that include new wiring are inspected at rough-in, with the walls still open, like other electrical work in the kitchen.
How Does Lighting Affect the Order of Work?
Lighting is one of the first things settled and one of the last to be seen. The rough wiring goes in with the walls open, then the ceiling is patched or the drywall hung, then the cabinets and countertop are set, then the backsplash tile, and only at the end do the trim kits and fixtures go on. Moving a can after the ceiling is finished means a new hole and a new patch, and the plasterer is not always on site the same week.
That is why the layout of lights is drawn on the same plan as the cabinets. The cabinet run sets where the task lights go, and the task lights set where the ambient lights should and should not be.
What Should the Final Walk-Through Check?
With the room finished, a crew turns every fixture on and looks at the surfaces, not the bulbs. Shadows on the countertop, glare off the backsplash, a dim corner by the range, or a switch that controls the wrong light are all easy to fix on the last day and annoying to live with afterward.
A good kitchen light plan is one the cook never thinks about. Put the light where the hands work, keep one color throughout, and give the old wiring a proper look before adding to it.
