What is the meaning of "light bulb color temperature"? Color temperature is a unit to measure the color component of light, with a unit of K (Kelvin). It represents the color of the light source. Just like when you heat up an iron, it first turns red, then yellow, and finally white.

Theoretically, color temperature refers to the color of a perfectly black body as it warms up from absolute zero (0 K) to a certain temperature. As the black body is heated, it gradually turns from black to red, yellow, and then white, emitting light with different components. The color of the light it produces at a certain temperature is called the color temperature at that temperature.

Color temperature is a way to measure temperature, typically used in physics and astronomy. It is based on a fictional black object that emits light of different colors when it is heated to different temperatures.

For example, the light we see usually consists of seven colors. Some of these colors are blue, while others are red. Color temperature is used to measure and calculate the color composition of light.

In normal situations, the lower the value, the warmer the light color; the higher the value, the whiter the light color. A color temperature of 3000 K is called warm white, which is close to the color of the sun. A color temperature of 6000 K is called natural white or cool white and appears more solemn.

In summary, color temperature is a way to measure the color of light and is used in various fields such as physics, astronomy, and lighting. It is important to know the color temperature when choosing lighting for different purposes.
