What is CCT about LED LIGHTS?

CCT stands for Correlated Color Temperature and is used to describe the color characteristics of light emitted from a light source. Its unit is Kelvin (K). In the field of lighting, CCT values are usually categorized into the following ranges:

 

1. warm white light (about 2700K-3000K): yellowish light, creating a warm, cozy atmosphere, commonly used in homes and restaurants and other places.

 

2. natural white light (about 3500K-4500K): light is neutral, neither too warm nor too cold, suitable for offices, schools and other environments.

 

3. cold white light (about 5000K-6500K): blue light, clear and bright, suitable for hospitals, shopping malls, factories and outdoor places that need high brightness.

 

CCT is just a numerical value describing the color temperature, which is different from the color rendering of the light source (e.g. CRI, Color Rendering Index). CRI indicates the ability of the light source to restore the color of the object, while CCT indicates the hue of the light.
