How Many Lights Do You Need in a Room?

Choosing the right number of lights is one of the most important parts of good home lighting. Too few lights can make a space feel dark, uneven, or tired. Too many can make it feel harsh, overlit, and uncomfortable - even with modern LEDs.

The guide below gives simple, real-world lumen targets for common rooms, based on typical Australian homes, layouts, and living habits. It’s designed to help you get lighting that feels right in everyday use, not showroom-bright or rental-dim.

We’ve assumed standard Australian ceiling heights, modern LED fittings, and average wall and floor colours. We’ve also already taken lux vs lumens into account and use lumens only, as that’s the number shown on every light box and the easiest way to plan how many fittings you need.

Recommended lumens by room type

Kids’ bedroom

• 2,000–2,500 total lumens ~3.0 × 3.0 m (9 m²)
• Comfortable brightness for play and homework without being harsh at night

Master bedroom

• 2,500–3,500 total lumens ~3.5 × 4.0 m (14 m²)
• Soft, even light for everyday use, with lamps doing the reading work

Living room

• 3,000–5,000 total lumens ~4.0 × 5.0 m (20 m²)
• Balanced general lighting that feels bright without glare

Open-plan kitchen / dining ~5.0 × 6.0 m (30 m²)

• 8,000–12,000 total lumens
• Higher output for cooking and dining, with task lighting added where needed

Bathroom

• 3,000–4,000 total lumens ~2.5 × 3.0 m (7.5 m²)
• Clear, shadow-free lighting for grooming and daily routines

Double garage

• 6,000–8,000 total lumens ~6.0 × 6.0 m (36 m²)
• Practical brightness for parking, storage, and workshop use

When choosing lights, focus on even coverage rather than raw brightness. Multiple lower-glare fittings spaced well will almost always feel better than a few very bright ones. Consider the colour temperature as well as the output - warmer light suits bedrooms and living areas, while neutral light works better in kitchens, bathrooms, and garages. Finally, think about how the room is actually used: ceiling lights provide general light, but task lighting (lamps, pendants, under-cabinet lights) is what makes a space genuinely functional and comfortable day to day.
