Color temperature refers to the color of the light emitted by a light source and is measured in Kelvin (K) . It describes how "warm" or "cold" the light feels, based on its radiance. Color temperature is therefore a way to measure whether light is yellow, white, or blue.
Color temperatures and their effect:
- Warm light (2700 K - 3000 K) : This light has a yellow or orange tint, similar to the light from a traditional incandescent bulb. It creates a cozy, calming atmosphere and is often used in living rooms, bedrooms, and dining rooms.
- Neutral white light (3500 K - 4100 K) : This light is less yellow and closer to natural daylight. It has a more balanced appearance and is often used in kitchens, workspaces, and offices.
- Cool white light (5000K - 6500K) : This light has a blue tint and is closer to the light of the blue sky or daylight. It is bright and energetic, making it ideal for workspaces, studios, or industrial environments.
Why is color temperature important?
- Ambience and comfort : Warm light (low K) creates a relaxing and cozy atmosphere, while cool light (high K) provides clarity and often promotes concentration.
- Applications : In certain spaces, such as workspaces or kitchens, cool white light can be helpful in creating sharp vision and a more energised feeling, while for bedrooms or living rooms, warm light can promote relaxation.
In short, color temperature determines how light behaves in terms of visual appearance and the atmosphere it creates.
