Understanding CCT in Lighting: What is Correlated Color Temperature and Why Does It Matter?

When choosing lighting for our homes, offices or outdoor spaces, we often come across the term CCT. But what does this abbreviation actually mean and how can it help us choose the ideal lighting?

What is CCT?

CCT (Correlated Color Temperature) refers to the color of light emitted by a light source and is measured in Kelvin (K). CCT does not describe the actual temperature of the light source, but rather the color characteristics of the emitted light. CCT ranges from warm, yellowish tones to cool, bluish hues.

How does the CCT scale work?

The CCT scale allows us to easily understand the tone of light:

Warm White (2700K – 3000K): This light has a yellowish tone that is reminiscent of the light of a sunset or traditional incandescent bulbs. Warm white creates a pleasant and relaxing atmosphere, making it ideal for living rooms, bedrooms and other spaces where we want to relax.

Neutral White (3500K – 4100K): This light is white in color without pronounced yellow or blue tones. Neutral white is a popular choice for office spaces, as it provides clarity without being too cold.

Cool White (5000K – 6500K): This light has a bluish tone similar to daylight at noon. Cool white light is often used in workspaces, garages, and outdoor lighting, where sharp visibility and focus are required.

Why is it important to understand CCT?

Choosing the right color temperature can significantly affect our experience of a space. For example, lighting that is too cool in a living room can create an undesirable sterile feeling, while too warm shades in an office can reduce productivity. Knowing the CCT scale allows you to choose lighting that best suits the function of the space and the atmosphere you want to create.

How to choose the right CCT for your space?

When choosing a light source, consider the purpose of the space and the atmosphere you want to achieve:

Living spaces: Choose warmer CCT values ​​(2700K – 3000K) to create a comfortable and relaxing atmosphere.

Offices and workspaces: Neutral to cool CCT values ​​(3500K – 5000K) will ensure clarity and productivity.

Outdoor lighting: Cool CCT values ​​(5000K – 6500K) will provide better lighting and safety.

Conclusion

CCT is a key factor in choosing lighting, as it directly affects the look and feel of a space. Whether you're decorating a new home, renovating an office, or simply looking to replace your light bulbs, understanding CCT values ​​will help you make the best choice for each space.

Choose wisely and illuminate your world with the right tone of light!
