What does CCT and LED color temperature K mean in LED lights?

CCT is the abbreviation of correlated colour temperature, which means the correlated colour temperature of LED lamps. Color temperature is a measure of the light color of a light source. It was first formulated by Kelvin, so Kelvin's name is used as a unit of measurement, and the English letter K is used as a representative symbol, and the unit is K (Kelvin)!

In physics, it is represented by the absolute temperature K, that is, the standard black body is heated. When the temperature rises to a certain level, the color of the black body begins to be dark red-light red-orange-yellow-white-blue, and gradually changes, and a light source has the same color as the black body. , we call the absolute temperature of the black body as the color temperature of the light source. The unit of measurement is Kelvin (°K) degrees. The lower the value, the stronger the red, and the higher the value, the stronger the blue.

Lights with different color temperatures have different lighting and visual effects as follows.
The color temperature is expressed by the absolute temperature K, which is to heat a standard black body (such as platinum), and when the temperature rises to a certain level, the color begins to gradually change from black to red, yellow, white, and finally emits blue light, gradually changing. , using the characteristics of this light color change, when the light color of the light source is the same as the light color of the black body, we call the temperature of the black body at that time the color temperature of the light source.
When the color temperature is around 3000K, the light color is yellowish. When the color temperature is above 5000K, the light color is bluish. Different color temperatures correspond to different colors of light as shown in the figure below.The color temperature of our High bay lights and LED Flood light can be from 2700-6500K, this brings you more choices!
