Lighting Design 101

How to plan lighting that works for the way you live, from the lighting specialists who specify it every day.

Good lighting starts with how a room is used, not with the fittings. Get that right and the rest is a handful of numbers: colour temperature, brightness and three layers of light.

This guide covers those foundations first, then walks through eight rooms. Each room links to a full guide in the Lighting Journal and to the matching collection.

Start with how the room is used

Every good lighting plan answers one question first: what happens in this room, and when? Most lighting that feels wrong, too harsh or too dim to read by, was chosen before anyone asked.

Walk through a normal day in the space and note three things:

  • The main purpose. Relaxing, focused work, or both. This sets your colour temperature and how bright the room needs to be.
  • The specific tasks. Reading in bed, chopping at the bench, working at a screen. Each one needs light aimed at it.
  • The mood after dark. How you want the room to feel at 9 pm decides how much accent light and dimming you plan.

A bedroom for someone who reads every night needs an adjustable reading light on each side. A bedroom for someone who scrolls their phone before sleep needs soft, low light instead. Same room, different plan.

The numbers that matter

Four numbers on a datasheet tell you most of what a light will do in a room. For the full glossary, see Technical Lighting 101.

Colour temperature (Kelvin, K) sets the mood. Lower is warmer and more relaxing; higher is cooler and more alerting.

Colour temperature How it looks Where we use it
2700K Warm, golden, like late-evening light Living rooms, bedrooms, dining, outdoors
3000K Warm white, a little crisper Kitchens, bathrooms, desks in shared rooms
3500K–4000K Neutral white Dedicated home offices, commercial spaces
5000K and above Cool, bluish daylight Workshops and detailed task areas only

Pick one colour temperature per room and stick to it. Mixing 2700K and 4000K in the same space makes both look wrong.

Brightness (lumens, lm) is how much light comes out. Compare lumens, not watts. As a guide, 450 lm is a soft glow (an old 40W bulb), 800 lm lights a small room (60W), and 1,600 lm suits a large space (100W).

Colour rendering (CRI) is how true colours and skin tones look, out of 100. Choose CRI 90 or higher at vanities, in kitchens and anywhere art is lit.

Dimming turns one light into several. Put your brightest layer on a dimmer, and check the fitting's dimming type matches the dimmer before installation.

Layer the light

A room lit by one overhead source looks flat. Combine three layers, each on its own switch or dimmer, and the same room can be bright for cleaning, focused for reading and soft for the evening.

01

Ambient

Fills the room so you can see and move safely. Usually downlights, a ceiling light or a pendant.

02

Task

Puts light where the work happens: the reading chair, the benchtop, the mirror. Reading lights, under-cabinet strips, adjustable spots.

03

Accent

Creates the mood and the depth. Wall washers, picture lights, a lamp in a corner, uplights in the garden.

A bedroom, for example: downlights or a ceiling light for ambient, a wall-mounted reading light each side of the bed for task, and a pair of wall washers for accent. Use them together in the morning, and only the accent layer at night.

Most rooms need at least two layers. Living areas, kitchens and voids work best with all three.

Which fitting does which job

Once you know the layers, choosing fittings is a matter of matching each one to its job. Style comes after.

Fitting Best at Watch for
Downlights Ambient light, and task light when adjustable Too many in a grid makes a room flat and glary
Ceiling lights Broad ambient light from one point Poor for tasks; one alone leaves corners dark
Pendants Ambient or focused light, and the room's statement piece Hang height: 75–95 cm above a dining table
Wall lights Accent and ambient; reading light by the bed Underused: most plans need more of them
Spotlights and track Aiming light at art, benches or features Glare if aimed at eye level
Marker lights Low, safe guidance on stairs and paths Spacing: closer together where ambient light is low
Table and floor lamps Flexible task and accent light, no electrician Need a nearby power point

Room by room

The same three layers apply in every room. What changes is the balance. Pick your room for the short version here, then read the full guide in the Lighting Journal.

Bedroom

Soft, warm and fully dimmable, with real reading light by the bed.

  • 2700K–3000K throughout; nothing cooler than 3500K
  • A wall-mounted reading light each side keeps bedside tables clear
  • Never put a bright light directly over where your head lies

Bathroom

The one room where the rules decide where a light can go.

  • Inside the shower (Zone 1), lights need at least IPX4; inside the bath or shower base (Zone 0), IPX7 and 12V
  • Light the mirror from the sides, at face height, not from above
  • CRI 90+ at the vanity so skin tones look true

Kitchen

Task light first: the benchtop is where it has to work.

  • Under-cabinet lighting removes the shadow your body casts on the bench
  • Fewer, wide-beam downlights beat a dense grid of narrow ones
  • Put pendants, downlights and strip lighting on separate switches or dimmers

Voids

A double-height space should be the best-lit feature of the house, not a dark shaft.

  • Scale the pendant to the volume: small fittings look lost
  • Light upwards as well as down, or the top of the void disappears
  • Asymmetric or wall-washing downlights keep it residential, not commercial

Home office

Task lighting does the heavy lifting.

  • 3500K–4000K in a dedicated office; about 3000K for a desk in a shared room
  • An adjustable desk or wall light on the work surface, not more downlights
  • Keep light sources behind or beside you, never reflecting in the screen
