Correlated Colour Temperature (CCT) and its application

by Tushar Bhala on August 09, 2023

Light is an essential element in our daily lives, influencing our mood, productivity, and overall well-being. One critical aspect of light is its colour temperature, often referred to as CCT (Correlated Colour Temperature). CCT is a numerical representation of the colour appearance of light emitted by a particular light source.

 

What is Correlated Colour Temperature?

Colour Temperature is measured in Kelvin (K) and represents the colour of light emitted by a light source when heated to a specific temperature. The higher the temperature, the cooler the light appears, and vice versa. This means that lower CCT values represent warmer, more yellowish light, while higher CCT values indicate cooler, bluish light.

Understanding CCT Values

Warm White (2700k – 3000K):


Warm white light closely resembles the colour of traditional incandescent bulbs. It emits a cosy and relaxing ambiance with its yellowish hue.

Warmer temperature is suited for rooms where one relaxes and carries out any leisure activity.

 

Natural White (3500k – 4500K):
Natural white light falls in the middle of the colour temperature spectrum, providing a balanced and natural lighting appearance. 

A Natural white tone is used is areas where focused work is done and is the prime choice for commercial areas, libraries and conferences. 

Cool White (5000k – 6500K):
Cool white light emits a bright and vibrant illumination that resembles natural daylight. It helps in making a space seem larger

Such high lumen white light is used in places where a lot of attention is required such as for photography, hosiptals, Industrial floors etc. 

 

Choosing the right CCT can significantly impact the ambiance and functionality of a space. By harnessing the power of different CCT values, we can create environments that not only serve their purpose but also enhance our overall experience in the spaces we inhabit.
