LED Lights for Every Room: How to Choose Watts, Brightness and Colour
Lighting changes how a home feels. The same room can look warm and cosy, or bright and fresh, depending on the lights you choose. Good lighting also makes everyday tasks easier: cooking, reading, studying and getting ready in the morning. LED lights have made lighting cheaper to run and longer lasting. But shopping for them introduces new terms: watts, lumens, colour temperature, CRI. This guide explains each one simply and gives you a practical room-by-room plan.
Watts vs Lumens: What Really Matters
In the days of old incandescent bulbs, we judged brightness by watts. A 100 watt bulb was brighter than a 60 watt bulb. With LEDs, watts only tell you how much electricity the light uses, not how bright it is. Brightness is measured in lumens.
| Old incandescent bulb | Approximate LED brightness | Typical LED wattage |
|---|---|---|
| 40 W | About 450 lumens | 5 to 6 W |
| 60 W | About 800 lumens | 8 to 10 W |
| 75 W | About 1100 lumens | 11 to 13 W |
| 100 W | About 1600 lumens | 14 to 18 W |
When comparing LED lights, look at lumens for brightness and watts for power use. More lumens per watt means a more efficient light.
| Colour | Kelvin range | Feel | Best for |
|---|---|---|---|
| Warm white | 2700 to 3000 K | Yellowish, cosy, relaxing | Bedrooms, living rooms, dining |
| Neutral white | 3500 to 4500 K | Balanced, natural | Living rooms, study, dressing |
| Cool white / daylight | 5700 to 6500 K | Bright, crisp, bluish | Kitchens, bathrooms, work areas |
Many homes in India use cool white everywhere, but mixing warm and cool lights by room creates a much more comfortable home.
Colour Rendering (CRI)
CRI tells you how naturally a light shows colours, on a scale up to 100. A CRI of 80 or above is good for homes. For dressing areas, art or makeup, a higher CRI helps colours look true.
Room-by-Room Lighting Guide
A simple way to plan is to think in three layers:
- General lighting to light the whole room
- Task lighting for specific jobs like cooking or reading
- Accent lighting for mood and decoration
Living Room
- General: LED panel lights or downlights, neutral or warm white
- Accent: Cove lights, wall lights or a statement fixture
- Tip: Use dimmable lights or separate switches so you can change the mood for movie nights or guests
Bedroom
- General: Warm white downlight or panel
- Task: Bedside reading lights
- Tip: Avoid very bright cool white lights before sleep; warm light is more relaxing
Kitchen
- General: Bright cool or neutral white panel or batten
- Task: Under-cabinet strip lights over the counter so you are not cooking in your own shadow
- Tip: The kitchen needs more brightness than any other room
Bathroom
- General: Moisture-resistant downlight or batten
- Task: Light near the mirror for grooming
- Tip: Choose fittings suitable for damp areas
Study or Home Office
- General: Neutral white panel
- Task: Desk lamp with good brightness
- Tip: Avoid glare on screens by placing lights to the side
Dining Area
- General or accent: Warm white pendant light over the table
- Tip: Hang pendants low enough to light the table without blocking the view
Balcony and Entrance
- General: Weather-resistant wall light or bulkhead
- Tip: A warm light at the entrance feels welcoming
| Room | Approximate brightness needed |
|---|---|
| Bedroom | 10 to 20 lumens per sq ft |
| Living room | 10 to 20 lumens per sq ft |
| Kitchen | 30 to 40 lumens per sq ft |
| Bathroom | 20 to 30 lumens per sq ft |
| Study | 30 to 50 lumens per sq ft at the desk |
Example: A 12 ft x 12 ft bedroom is 144 sq ft. At about 15 lumens per sq ft, it needs around 2,200 lumens in total, which might be two or three downlights plus a bedside lamp.
Popular Types of LED Lights

Frequently asked questions
- Colour Temperature: Warm, Neutral or Cool?
- Colour temperature is measured in Kelvin (K) and describes how warm or cool the light looks.
- How Much Light Does a Room Need?
- A rough guide for Indian homes:
- What is better for home: warm white or cool white?
- Use both. Warm white for bedrooms and living areas, cool or neutral white for the kitchen, bathroom and study.
- How many watts LED bulb do I need for a bedroom?
- It depends on room size and lumens. For a typical bedroom, a total of about 1,500 to 2,500 lumens across the lights works well, which is often 2 to 3 LED downlights.
- Do LED lights save electricity?
- Yes. LEDs use far less electricity than incandescent bulbs and CFLs for the same brightness, and they last much longer.
- Can I change my tube light to an LED batten myself?
- It usually needs basic wiring. For safety, ask an electrician to do it.
