Correlated color temperature(CCT) refers to the correlation of the heat produced to the color of the light. Most heat sources and light sources correspond to temperatures and color.

Scientists use CCT to gather the approximated temperature of a light source such as stars and other stuff in space. Artists and photographers also use warm and cool tones with lighting to depict what type of mood they want to express.

CCT is commonly measured with the kelvin system hence the (k) symbol is placed on the last part of the label. Most LED lights have a range from 1000k to 10000k.

Kelvin pertains to the measurement of the white light’s temperature. The lower it goes, the warmer the tone, while higher kelvin means that the light will have a cooler tone. The Kelvin measurement is a tool used to distinguish color and temperatures.

For example, lights that fall in the 2000k category will have a yellow-orange tone compared to a light that is 5000k, which has a paler and whiter color. You will notice that lights nearer to 1000k will have a more orange color while lights closer to 10000k lean to blue.

By knowing where your light falls on the spectrum, you can ensure that you can have the right lights for your needs.
