Home lighting: how to plan the three layers of light

In short

Good home lighting has three layers: ambient (even light across the whole room – hidden LED lines, recessed spotlights), task (where you cook, read, work or do your make-up) and accent (backlit niches, artwork, display cabinets and wall lamps for atmosphere). For a home, warm light of around 2700–3000 K with dimming is recommended. Lighting is planned in the design, before the rough works, because the cables are laid in the walls and ceiling.

Lighting is the most underestimated part of the interior. You can choose the most beautiful materials, but if the light is wrong, the home will look flat, cold or tiring. And the reverse – well-planned light makes even the simplest space cosy. Here is how we plan lighting in every project.

The three layers of light

1. Ambient lighting

This is the main light that lets you move around safely and see the whole room. Instead of one chandelier in the centre, today we use hidden LED lines in the suspended ceiling, recessed spotlights or linear profiles. The aim is even light, with no dark corners and no glare.

2. Task lighting

Directed light where precision is needed: over the kitchen worktop, the desk, the bathroom mirror, the bedside table for reading. It is brighter and must be positioned so you don't cast a shadow on what you are doing.

3. Accent lighting

The light that creates atmosphere – backlit niches and display cabinets, a lamp above a painting, wall sconces, an LED strip behind the headboard or under a wall-hung cabinet. Accent lighting adds depth and makes the home cosy in the evening.

Colour temperature and brightness

Colour temperature	Feeling	Where
2700 K	Warm, cosy	Living room, bedroom, dining room
3000 K	Warm-neutral	Kitchen, bathroom, corridors
4000 K	Neutral, “working”	Walk-in closet, utility room, office

It is important that all sources in one room have the same colour temperature – mixing warm and cold light looks restless. Pay attention to the colour rendering index (CRI) too – with CRI above 90, the colours of materials and skin look natural.

LED strips and hidden lighting

In the suspended ceiling – indirect light that “lifts” the ceiling and makes it feel higher.
Under the kitchen wall cabinets – task light on the worktop.
Around mirrors – even light for the face.
In niches and display cabinets – highlights the objects.
Around the plinth of furniture – night light that doesn't wake you.

Profiles with a diffuser hide the dots of the LED strip and give an even line of light. Drivers must be accessible for replacement – this is decided in the design.

Lighting room by room

Living room

Hidden ambient lighting, a floor lamp by the sofa, wall lamps and backlighting for the TV wall or bookcase. All dimmable, so there are different scenes. More ideas in living room interior design.

Kitchen

LED under the wall cabinets is a must, pendant lamps over the island or table and even ambient lighting. Find out more about kitchen interior design.

Bedroom

Soft ambient light, reading lamps on both sides of the bed (so you don't disturb each other), backlighting behind the headboard and wardrobe lighting that switches on when you open it.

Bathroom

Even light around the mirror, moisture-protected fittings in the shower area (with the right IP rating) and soft backlighting in niches for evening relaxation. More in bathroom interior design.

Entrance hall and corridor

Lighting with a motion sensor and night mode. The mirror in the entrance hall deserves its own light.

Control and lighting scenes

Dimmers are the simplest way to adapt lighting to the moment. With a smart system you can create scenes – “morning”, “dinner”, “film”, “night” – and switch them on with one button or from your phone. More about this in the article on the smart home.

When lighting is planned

Lighting is decided in the interior design project, before the rough works. That is when the positions of all light fittings, switches, power supplies and cables are set. Once the walls are plastered, every change means breaking them open. See the right order of renovation stages.

The most common lighting mistakes

One chandelier in the centre of the room and nothing else.
Cold light in living spaces.
Different colour temperatures in one room.
Spotlights directly above your head when eating or reading.
No task lighting over the kitchen worktop.
Switches in inconvenient places.

Frequently asked questions

What light is best for the home?

Warm light around 2700–3000 K with a high colour rendering index (CRI 90+) and the option to dim.

How many light fittings does a room need?

At least three sources at different heights – ambient, task and accent lighting. The exact number depends on the size and function of the room.

Is hidden LED lighting enough as the main light?

In most cases yes, if it is well positioned. We often combine it with recessed spotlights for stronger light when needed.

When should I decide on the lighting?

Before the rough works – in the design. That is when the cables are laid and the suspended ceilings are built.
