The right LED bulb comes down to three things: the fitting (E27 or B22), the colour temperature, and the brightness for the room. Here's how to choose for a Singapore home, room by room.
Quick answer
For most Singapore living rooms and bedrooms, a 9–12 W LED bulb in your existing E27 or B22 fitting gives ample light. Pick warm white (2700–3000K) for bedrooms and living rooms, and cool white (4000–6500K) for kitchens, study and bathrooms.
E27 vs B22: which fitting do I have?
- E27 — screw-in (Edison screw). Common in newer fittings and many lamps.
- B22 — bayonet (push and twist). Common in older HDB fittings.
Check your old bulb's base, or bring it along to match.
Colour temperature by room
| Room | Colour | Kelvin |
|---|---|---|
| Bedroom, living | Warm white | 2700–3000K |
| Kitchen, study, bathroom | Cool white | 4000–6500K |
| Display / retail | Daylight | 6500K |
How bright? (lumens, not watts)
With LED, judge brightness by lumens, not watts. As a guide, a 9 W LED ≈ 800 lumens ≈ a traditional 60 W bulb. A small bedroom needs 600–800 lumens; a bright kitchen may want 1,000–1,500 lumens total.
Why switch to LED?
LED bulbs use up to 80% less electricity than incandescent and last far longer — a clear win in Singapore where lights run daily. Look for energy-saving models with a local warranty.

Frequently asked questions
Warm white or cool white for a Singapore home?
Warm white (2700–3000K) for bedrooms and living rooms; cool white (4000–6500K) for kitchens, study and bathrooms.
What's the difference between E27 and B22 bulbs?
E27 is a screw-in base; B22 is a bayonet (push-and-twist) base common in older HDB fittings. Match your existing bulb's base.
How many lumens do I need?
About 600–800 lumens for a small bedroom and 1,000–1,500 lumens for a bright kitchen. A 9 W LED is roughly 800 lumens.
Do LED bulbs really save electricity?
Yes — LEDs use up to 80% less power than incandescent bulbs and last far longer, lowering your bills over time.
