Home Lighting Plan: The Room-by-Room Guide

Lighting is the one element in a home that changes everything — and the one that almost everyone plans last. That's the mistake.

A good lighting plan isn't about choosing beautiful fixtures. It's about understanding how each room is used, then placing light intentionally. Here's the foundation you need — room by room.

Start With the 4 Types of Lighting

No single light source can do everything. Every well-designed room layers at least three of the following:

• Ambient — the base layer. General ceiling lighting that lets you move safely through the space.
• Task — focused light where you work, cook, read, or groom. Always in front of you, never behind.
• Mood — indirect, soft light that makes a room feel warm. Floor lamps, LED strips, table lamps.
• Accent — highlights art, shelves, plants, or walls. Adds depth and a curated feel.

Rule: A single overhead light is never enough, no matter how nice the fixture. Every room needs a minimum of 3 light sources across different layers.

The 3 Specs That Actually Matter

Kelvin (color temperature) — Use 3000K as your standard throughout the home. It's warm without being yellow, and works in every room. Reserve 2700K for bedrooms, and 4000K only at bathroom mirrors or desk lamps where you need sharp clarity.

CRI (Color Rendering Index) — Always choose CRI 90 or higher. Below that, materials, wood, and fabrics lose their richness. A low-CRI bulb makes expensive interiors look budget.

Beam angle — 60° for general light, 45° for task areas, 15–30° for accent. Narrow angles highlight; wide angles illuminate.

Spot Placement: The Rules Designers Use

The most common mistake is placing spots by feel rather than by measurement. These rules apply to standard 2.4–2.7 m ceiling heights:

• Place spots 60–80 cm from the wall — not flush against it.
• Keep 90–120 cm between spots for even distribution.
• Always use furniture as your reference, not the geometric center of the room.
• Never place a spot above the TV, directly above the bed, or behind your work position.
• Light should always fall in front of where you sit or stand — not behind you.

Per room, in short: Living room: light falls in front of the sofa, not behind it. Kitchen: under-cabinet strips are non-negotiable. Bedroom: no spot above the bed — use side or indirect lighting. Bathroom mirror: side lighting at eye level (≈160 cm), not from above.

Always Install Dimmers

Dimmers are not optional. Without them, you're locked into one brightness level for every time of day, mood, and activity. Every circuit in every room should be dimmable — this single decision transforms how a home feels from morning to evening.

FAQ

What are the 4 types of lighting in interior design? Ambient, task, mood, and accent. A well-designed room always combines at least three of these types — a single overhead source is never enough.

What Kelvin temperature is best for home lighting? 3000K for most rooms. Use 2700K in bedrooms for a warmer feel, and 4000K only for task-specific areas like the bathroom mirror or a desk lamp.

How far from the wall should recessed spotlights be placed? 60–80 cm from the wall, with 90–120 cm between spots. Use furniture — not the room's center — as your reference point for placement.
