Short answer
Light every room in three layers: ambient (general fill), task (light on the surface where you actually do something) and accent (the decorative and dramatic layer). Each layer needs its own switch, and everything should dim.
For a warm domestic result, choose bulbs around 2700K, keep the color temperature consistent throughout the house, and look for a CRI above 90 so materials and skin tones look right. All of this must be decided before drywall goes up, because it determines wiring.

The three layers
Ambient
The general light that lets you move around and see the room as a whole. Recessed downlights, a central fixture, cove lighting, or light bounced off the ceiling from floor lamps. Ambient light alone is flat — it is the base, not the design.
A note on recessed lights: they should be positioned relative to what they light, not laid out as a symmetric grid. Cans placed on a grid inevitably wash the middle of the ceiling and leave the counters, art and reading chairs in shadow.
Task
Light aimed at a surface where something happens: the kitchen counter, the desk, the book, the mirror. Task lighting is the layer people most often skip and most often miss. Overhead light puts your own shadow onto the counter you are chopping on — under-cabinet lighting exists precisely to solve that.
Accent
The layer that creates atmosphere and hierarchy: a chandelier, pendants, picture lights, cabinet lighting, uplights on a plant, a lamp glowing in a corner. This is the layer people notice and photograph, and it only works when the other two are right.
A useful test: at night, turn off the overhead lights entirely. If the room is unusable, the ambient layer is doing all the work and the design is unfinished.
Color temperature, CRI and dimming
| Spec | What to choose | Why |
|---|---|---|
| Color temperature | 2700K for living spaces; 3000K acceptable in kitchens and baths | Warm light is what a home is supposed to feel like. 4000K and above reads as an office |
| Consistency | The same temperature throughout a sightline | Mixed temperatures in one view look like a mistake, because they are |
| CRI (color rendering) | 90+ | Below 90, fabrics go gray, wood goes flat and food looks unappetizing |
| Dimming | Everything, on quality dimmers matched to the fixture | A kitchen at 7am and at 9pm are different rooms |
| Beam angle (recessed) | Narrow to highlight, wide to fill | One beam angle everywhere gives you no control |
| Warm dimming | Worth it in living and dining rooms | The light warms as it dims, the way incandescent used to |
Two practical warnings. Cheap LEDs flicker, sometimes below conscious perception but enough to cause headaches and to ruin video. Buy from a reputable manufacturer and check the dimmer compatibility list — mismatched LED and dimmer is the usual cause of buzzing and flicker. And bulbs are not interchangeable after the fact in integrated LED fixtures: when the LED fails, the fixture is done. That is a legitimate reason to prefer fixtures that take replaceable lamps in places you care about.
Heights and sizes that are always right
| Fixture | Height / size |
|---|---|
| Chandelier over a dining table | 30–34″ above the tabletop; width roughly ½ to ⅔ the table width |
| Pendants over an island | 30–36″ above the counter, 24–30″ apart, at least 6″ in from each end |
| Entry fixture | Bottom at least 7 ft above the floor; in a two-story entry, centered in the window |
| Bathroom sconces | Roughly 60–66″ from the floor, flanking the mirror, 36–40″ apart |
| Wall sconces generally | Centered about 60–66″ from the floor |
| Table lamp beside a chair | Bottom of the shade near seated eye level, about 40–42″ from the floor |
| Under-cabinet lights | Toward the front of the cabinet, so light falls on the counter not the backsplash |
| Recessed cans from a wall | About 24–30″ out, so the beam washes the wall rather than skimming it |
The chandelier sizing rule that avoids most errors: add the room's dimensions in feet, and the result in inches is a reasonable fixture diameter. A 14 by 16 foot room suggests a fixture around 30 inches across. Adjust for ceiling height and for how much presence you want, but the arithmetic is a good sanity check against a fixture that will look apologetic.
Room by room
Kitchen
Under-cabinet task lighting is non-negotiable. Add recessed or surface fixtures positioned over the working zones, decorative pendants over the island, and consider in-cabinet lighting behind glass fronts. Three circuits minimum. See the kitchen guide for how lighting fits the wider sequence.
Living room
Aim for at least five light sources at different heights: a couple of table lamps, a floor lamp, something architectural, and picture or accent lighting. Put lamps on switched outlets so one switch by the door brings the room up. A living room lit entirely from the ceiling never feels comfortable.
Dining room
The chandelier is the accent layer, not the working light. Add discreet ambient light — recessed or wall washers on the art — so the room is not a bright island of table in a dark space. Dim the chandelier low at dinner and let the room around it carry.
Bathroom
Light the face from both sides, not from above; a single overhead fixture casts shadows straight down. Add ambient light for the room and a low-level night light on its own switch. Details in the bathroom guide.
Bedroom
Independent light on each side of the bed, reachable without getting up. Wall-mounted or pendant reading lights free the nightstand. Keep the overall level low and warm, and put any overhead fixture on a dimmer.
Stairs and hallways
These are safety spaces before they are design spaces: even light, no dark treads, and three-way switching at both ends of every run and every flight. A hallway also benefits enormously from wall washing on art rather than downlights in a line.
Switching: the decisions that come before drywall
This is the part that cannot be fixed later without opening walls, and it is where most homes are quietly compromised.
- Separate the layers. Ambient, task and accent each on their own switch. If they share one, you have one lighting scene, forever.
- Three-way and four-way switching wherever a room has two or more entrances, and at both ends of every hallway and stair flight.
- Switched outlets for lamps, so a wall switch controls them. Decide which half of which outlet, and where.
- Dimmers everywhere, sized for the load and compatible with the LEDs specified.
- Switch position. On the latch side of the door, at a consistent height, not behind a door that will be open most of the time.
- Decide about smart controls early. Whether the system is app-based or conventional changes the wiring, the boxes and the neutral requirement.
- Exterior and landscape lighting needs its own circuit and control, plus a timer or photocell.
All of this belongs on the plan and elevations before rough-in, which is the point in the remodel sequence where the layout becomes permanent.
Common lighting mistakes
- A grid of downlights and nothing else. Flat, shadowless and unflattering to everything in the room, including the people.
- Mixed color temperatures within one sightline. Buy all the bulbs at once and write the specification down.
- Pendants centered on the room rather than on the island. They must relate to what they hang over.
- Undersized fixtures. Fear of "too big" produces fixtures that look lost. Use the room-dimension rule.
- No dimmers. The cheapest upgrade in the entire house, skipped constantly.
- Recessed cans in a sloped ceiling without sloped-ceiling trims, so every beam points at the far wall.
- Nothing lighting the art. Art in shadow is decoration you paid for and cannot see.
- Forgetting daylight. Where windows face, and what window treatments do to that light, is half of a room's lighting design.
Key takeaways
- Three layers — ambient, task, accent — each independently switched, all dimmable.
- 2700K and CRI 90+ for a warm, true-color home; keep temperature consistent within a sightline.
- Chandelier 30–34″ above the table; pendants 30–36″ above the island.
- Add the room dimensions in feet for a sensible fixture diameter in inches.
- Bathroom light comes from beside the mirror, never only from above.
- Switching, three-ways and switched outlets are wiring decisions — make them before drywall.
