CCT, or Correlated Color Temperature, is a measure that describes the color shade of a light source, expressed in Kelvin (K). This shows how much light there will be in the room:
Warm white light (approx. 2700-3000 K) gives comfort and is suitable for living rooms.
Neutral white light (around 3500-4100K) is versatile and often used in offices and commercial spaces.
Cool white light (around 5000-6500K) simulates daylight and is suitable for industrial and production rooms.
The choice of CCT can affect the mood, productivity and general atmosphere of the rooms, so it is an important consideration in lighting planning.
What makes CCT significant?
CCT (Color Temperature Index) is significant for several reasons:
Considering Mood : CCT can have a big impact on the atmosphere and mood of a space. Warm white light (2700-3000K) creates a sense of coziness, while cool white light (5000-6500K) promotes energy and focus.
Work efficiency : Neutral white light (3500-4100 K) is important for office and production lighting, as it helps maintain worker productivity and reduces fatigue.
Color separation : CCT is important when choosing lighting where precise color separation is required, such as in art studios or design offices.
Ergonomics : The right choice of CCT can help reduce eye fatigue and discomfort, especially when working for a long time at the computer or intensively working in the dark. Aesthetic value : CCT helps to create visual integrity and aesthetic effects in the interior, so it is important to combine light sources with the overall design concept of the space.
Office and office lighting
Efficiency is very important when working
In offices where computers are used, neutral white light (3500-4100 K) is often recommended. Such light helps reduce eye fatigue and promotes focus, allowing workers to work more efficiently and for longer.
Industrial and industrial lighting Ergonomics and comfort
In industrial settings such as factories where precision tasks are required, cool white light (5000-6500K) can help you see details and colors better. This reduces the chance of errors, improves working conditions and reduces the risk of poor visibility.
Shop lighting Aesthetics and corporate image
When choosing lighting for customer service areas, such as shops or offices, warm white light (2700-3000 K) creates a feeling of coziness, which can positively affect the mood of customers and promote loyalty.
Street lighting Security
Cool white light (5000-6500K) is often used for street lighting as it provides better visibility and clarity at night. Such lighting helps drivers and pedestrians to better see obstacles, signs and other people on the road, thus increasing safety.
Park lighting A visual experience
Neutral white light (3500-4100K) can be used in pathways and parks to create a pleasant and attractive environment. Such lighting can better emphasize natural beauty such as trees and flower beds, which encourages people to use these trails.
Lighting of sports halls and stadiums Visibility of players
Cool white light (5000-6500K) is often used in gyms and stadiums because it provides better contrast and helps players see the ball and other elements of the game more clearly. This helps ensure a smoother game and reduces the chance of errors.
