What is Correlated Color Temperature?
It is described as the color temperature of a light source measured in Kelvin (K), which characterizes the hue of the light emitted by the source, indicating whether it appears yellow/red (warm) or blue (cool). The CCT is calculated by comparing the color of the light source to the color of light generated by an ideal black body radiator heated to a certain temperature.
Correlated Color Temperature Chart
Below we listed some CCT types with their values –
CCT | Value | Output |
---|---|---|
1. Lower CCT ( Warm Light ) | 2700K – 3000K | It emit a yellowish, reddish light. Examples include incandescent bulbs and candlelight. |
2. Mid-range CCT ( Neutral Light ) | 3500K – 4100K | It emit a balanced white light. |
3. Higher CCT ( Cool Light ) | 5000K – 6500K | It emit a bluish light, similar to daylight. |
Applications of CCT in Lighting
Here we have listed some useful applications of CCT in lighting –
- Warm Light: Creates a pleasant, soothing ambiance; ideal for home, restaurant, and hospitality settings.
- Neutral Light: Ideal for offices, classrooms, and retail businesses, it provides even and comfortable illumination.
- Cool Light: Improves alertness and visibility; ideal for hospitals, laboratories, and outdoor illumination.
