Warm, cool or neutral? Choosing the colour temperature
What the numbers in Kelvin mean and which colour of light suits which space.
The colour of a bulb is measured in Kelvin (K). It is printed on the box or on the product page, and it changes how a room feels more than most people expect.
Warm white, around 2700K to 3000K, gives a yellowish, cosy light. It suits living rooms, bedrooms and dining areas, and it makes wood, fabrics and warm colours look rich. Neutral white, around 4000K, is clean and balanced, and works well in kitchens, offices and bathrooms. Cool white, 5000K and above, is bluish and very bright, and is better kept for workshops, garages and places where you need to see small details.
Try not to mix very different colours in the same room, because the difference looks untidy. If you want flexibility, choose lamps that offer several colour options or that can be dimmed.
Also check the brightness, which is measured in lumens, not in watts. LED bulbs use much less power than older bulbs for the same brightness, so compare lumens when you choose.
