How to Plan Home Lighting, Room by Room

Lighting is the cheapest way to transform a home — and the most commonly botched. The secret isn't more light; it's the right layers of light.

3 layersAmbient + task + accent
2700–3000KWarm, for living spaces
4000K+Cool, for kitchens/baths

The three layers

  • Ambient — general fill (cove lighting, downlights).
  • Task — focused light where you work (under-cabinet, reading lamps).
  • Accent — drama and depth (wall washers, picture lights).

Get the colour temperature right

RoomTemperatureFeel
Living & bedrooms2700–3000KWarm, cosy
Kitchen3500–4000KClean, functional
Bathroom3500–4000KFresh, accurate
Study / workspace4000KAlert, focused

Room-by-room tips

  • Living — layer cove + a floor lamp + accent on art. Avoid one central light.
  • Kitchen — under-cabinet task lighting removes counter shadows.
  • Bedroom — bedside task lights on dimmers; keep ambient soft.
  • Bathroom — light the mirror from the sides, not just overhead.

Common mistakes

One harsh ceiling light flattens every room. Add dimmers, mix warm and functional zones, and never rely on a single source — layered light is what makes a space feel designed.

Frequently asked questions

How many lights does a room actually need?

Rough rule: 70–100 lumens per sq ft for living spaces. A 150 sq ft room needs ~12,000–15,000 lumens spread across ambient, task and accent sources — not one 20W panel.

Are smart lights worth it in India?

For dimming and scenes, yes — smart bulbs and switches now cost little more than premium regular fittings. Start with living and bedroom circuits rather than the whole house.

Warm white or cool white for homes?

Warm (2700–3000K) for living and bedrooms, neutral-to-cool (3500–4000K) for kitchens and task areas. Mixing them zone-wise is what professionals do.
