What is Kelvin in lighting?

Kelvin in lighting indicates the light colour emitted by a lamp. It is an important specification because the light colour strongly influences how a room feels. Kelvin does not describe brightness, but only the tone of the light: from warm and atmospheric to cool and functional.

What does the Kelvin value mean?

The lower the Kelvin value, the warmer and more yellow the light appears. The higher the Kelvin value, the whiter to bluer the light becomes. Choosing the right Kelvin value is essential for both atmosphere and functionality.

Different light colours explained

In lighting, three main Kelvin ranges are commonly used:

• Warm white light (2200K – 3000K)
  Creates a cosy and relaxing atmosphere. Ideal for living rooms, bedrooms and hospitality settings.
• Neutral white light (3500K – 4000K)
  Provides a fresh, natural look and is widely used in kitchens, bathrooms and offices.
• Cool white / daylight white light (5000K – 6500K)
  Bright and functional lighting, suitable for workshops, garages and practical workspaces.

Why is Kelvin important when choosing lighting?

The right light colour prevents a room from feeling too cold, uncomfortable or insufficiently lit. By considering the purpose of the space and the desired atmosphere, you can easily choose the correct Kelvin value and get the most out of your lighting.
