How to Plan Lighting at Home: An Interior Designer's Rules for Calm, Warm Light
In my studio, good home lighting is mostly indirect: light from coves, joinery and walls rather than from visible bulbs, one warm color temperature of 3000K throughout, high color rendering (CRI above 90), and dimmable scenes for day, evening and night.

Lighting is the part of a renovation people think about last and notice first. A beautiful room under the wrong light looks flat, cold or tiring. Lighting follows a short list of rules in every project, from a small apartment to a private house.
Key takeaways
Start with indirect architectural light, and keep light sources out of sight.
Use one color temperature, 3000K, in every room and every fitting.
Choose fittings with a CRI above 90, so materials and skin look natural.
Use few, trimless downlights, aligned with the ceiling and the joinery.
Make everything dimmable, with two or three scenes per main space.
Common lighting vs. architectural lighting
Common approach | Architectural approach |
Many downlights in a grid | Few trimless downlights, aligned with the joinery |
Visible bulbs and fittings | Hidden coves and strips in the ceiling and joinery |
Mixed warm and cool light | One color temperature, 3000K |
One switch, one level | Dimmable scenes for day, evening and night |
Several decorative pendants | One statement fixture per space |
Start with indirect light
Indirect light means the light source is hidden and you see only its glow, for example a LED strip in a ceiling slot, under or above joinery, or washing a wall. It's the base layer of a calm room, because it lights surfaces instead of shining into your eyes. Plan it with the ceiling and the joinery, before construction, because it lives inside them. In the S apartment in Hod Hasharon, an 8 cm lowered ceiling across the home carries the air-conditioning ducts and the recessed lighting, so the whole ceiling stays at one height.
One color temperature: 3000K
Color temperature describes how warm or cool white light looks, measured in kelvin. In my projects, every space and every fitting is 3000K: living rooms, bedrooms, kitchens, bathrooms, coves and tracks. It's warm enough to feel like home and clear enough to work by. Mixing temperatures makes a home look patchy, as if every room was lit by a different person.
Color rendering: CRI above 90
CRI (color rendering index) measures how faithfully a light source shows colors, on a scale up to 100. I specify a CRI above 90 for every fitting. With a low CRI, wood, stone and skin tones look dull and slightly off. With a high CRI, the materials you chose look the way they do in daylight, so check the light as well as the sample in the showroom.
Fewer downlights, and in line
A ceiling full of round holes, sometimes called a Swiss cheese ceiling, is the most common lighting mistake. Use few downlights, trimless and recessed, and align them with the ceiling grid and the joinery. In the MG House, recessed linear lights draw clean, continuous lines across the kitchen and dining space instead of a scatter of spots.
Magnetic tracks for accent light
For accent and task light, I use recessed magnetic tracks, trimless and flush with the ceiling, in the color of the ceiling or of the project's metal. Spots can be moved and aimed as the room changes. Even where a track is surface-mounted, as in the main bedroom of the BN apartment, keep it to one straight line in the project's metal, here black, above the gray wall cabinet and its pink dressing niche.
One statement fixture per space
Decorative pendants are the jewelry of the room, so limit them to one statement fixture per space, usually over the dining table or the kitchen island. In the RA apartment, a vintage asymmetric Stilnovo pendant in black, white and brass is the only decorative fixture, hung above the dining table so the ceiling doesn't feel visually busy. A recessed light strip runs along the window wall, with spots and task light over the island and the worktop.
Scenes: day, evening, night
Everything should be dimmable, with two or three scenes in each main space. By day, daylight leads and artificial light only fills in. In the evening, coves and wall light take over. At night, a low scene guides you through the home without waking anyone. For more on making the most of daylight, read how to bring natural light into a dark room.
Frequently asked questions
What color temperature is best for a home?
3000K is a warm white that suits living rooms, bedrooms, kitchens and bathrooms. Using it everywhere keeps the home consistent.
What does CRI mean in lighting?
CRI, the color rendering index, measures how accurately light shows colors. A CRI above 90 makes wood, stone and skin look natural.
How many downlights does a room need?
Fewer than most people think. Start with indirect light and add a few trimless downlights, aligned with the ceiling and the joinery.
What is a Swiss cheese ceiling?
It's a ceiling with many scattered round downlights, which looks busy. A few trimless downlights, aligned with the joinery, look much calmer.
What is indirect lighting?
Indirect lighting hides the light source, for example in a ceiling cove or behind joinery, so you see a soft glow instead of a bulb.
When should I plan lighting in a renovation?
At the start, together with the ceiling, the joinery and the electrical plan, because indirect light and recessed tracks are built into them.
