Episode 13 - Chromaticity - Kelvin is not Kevin

When you think about lighting your home or workspace, you probably focus on the brightness, energy consumption and style of the bulbs. However, there is one more important characteristic that you shouldn't ignore, and that is the chromaticity of the bulbs, which affects your productivity. Chromaticity refers to the colour characteristics of the light emitted by the bulb and can have a significant impact on the atmosphere and perception of a space. In this article, we'll look at what chromaticity means, why it's important, and how to navigate it.

Chromaticity:

Chromaticity, often referred to as colour light temperature or colour temperature, expresses how we perceive the light of a bulb. This characteristic is usually given in Kelvin (K) and is referred to as Kelvin colour temperature. Lower Kelvin values (for example, 2700K) indicate warmer, yellow light, while higher values (for example, 5000K) indicate cooler, white light.

What should one know about chromaticity?

When selecting bulbs with regard to chromaticity, it is important to consider the context and purpose of the lighting. Here are a few points to consider: 1) Context of the space: consider the purpose of the room and the desired atmosphere. Warmer light is more appropriate for relaxing spaces, while cooler light may be appropriate for work or function spaces. 2) Kelvin temperature: Familiarize yourself with the range of Kelvin values and understand what kind of light each value represents. In general, lower values (up to 3000K) are warmer, while higher values (above 5000K) are cooler. 3) Bulb selection: most manufacturers list the Kelvin temperature on the bulb packaging. So when buying, take note of this information and choose bulbs according to your preference for chromaticity.

Why chromaticity is important:

Chromaticity can have a significant impact on mood, productivity and perception of space. Warmer light (with lower Kelvin values) often creates a cosy and relaxing atmosphere that is ideal for living rooms, bedrooms and other environments where well-being is important. Conversely, cooler light (with higher Kelvin values) can be suitable for workspaces where increased attention and concentration is needed, such as offices or kitchens.

How to navigate?

If you're not sure what Kelvin temperature is right for you, try different types of bulbs in your space and observe how they affect the atmosphere. You can also consult with lighting experts to help you choose bulbs that match your needs and preferences.

The chromaticity of bulbs is an important factor that should not be overlooked when choosing lighting. The right colour temperature of light can create a pleasant and functional atmosphere in your home or workspace. Taking into account the context and the desired mood, choose bulbs with the appropriate chromaticity and enjoy optimal lighting in your daily life.
