• Have you ever thought about the concept of 2700K, 3000K, 3500K, 4000K, 5000K, 6000K that appear in the lamp parameters?
  • When you see the yellow light and white light in the introduction of the lamp, do you think it is too abstract?
  • Should color temperature or color be used to communicate with designers or lighting manufacturers?
  • What color temperature should be selected for different spaces?


What is color temperature?

Simply put, color temperature is the color of light. The unit of color temperature is to use Kevin as the unit of measurement, and the English letter K as the symbol. If you often see the packaging of lamps and lanterns or hear the designer say 3000K, 4000K, 5000K, they are talking about color temperature and lighting color.

How does the color temperature have anything to do with Kevin? Because it happens that Brother Kevin himself sells steel and maybe a steel tycoon. In the beginning, when Kevin observed dissolved metal in the factory, from the beginning to the highest temperature, the heated steel It is bright and will show different changes in color, and Kevin records the color of the iron block with data, and later produces a specification table of color temperature!

When the temperature of burning black iron is not high, the color of the iron will be orange-red, and it will gradually turn yellow as the temperature increases, and the iron block at the highest temperature will turn white, so the K value of the color temperature is similar in this concept, the yellower the color of the light, the lower the color temperature is, for example, 2700K and 3000K represent yellow light, while 5000K and 6000K represent white light.

In fact, color temperature is not Kevin's patent. Kevin may be more careful and observed this phenomenon because, at that time, he could not use mobile phones when burning steel, so he had to look at steel and think. You can refer to the change of the sun at different times in the picture below, which is actually the performance of color temperature. Therefore, color temperature is not only observed by burning iron but human beings have been immersed in the change of light color since birth.

Does yellow or white light let people feel abstract?

In this case, it is recommended to directly use the color temperature to communicate more accurately. At present, the products on the market will use Warm White, Cool White, and Day Light to indicate the color of the light, and some manufacturers use Warm White, Neutral White, and Cool White to indicate the color. Just focus on the literal meaning, each person's definition is very different, and it is easy to cause confusion.

To give another example:

  • The outer packaging of some lamps and lanterns defines the yellow light as 3000K, while others define the yellow light as 2700K, both of which are also yellow light, but the color temperature is still different;
  • 4000K, some people call it natural light, and some people call it warm white light;
  • In the representation of Chinese characters, some brands call 3500K yellow and white light, and some brands call 3500K warm white light or light warm light.

How to choose the color temperature for different spaces?

What color temperature light should be used in what space is actually a very subjective issue. As the saying goes: "green vegetables and radishes have their own advantages", there is no standard answer for the choice of the color temperature of space lighting, because everyone has different views and standards, and the definition of good and bad is also subjective. But there are still some tips for planning your lighting:

  • The appropriate color temperature can be planned according to the purpose of the space and the people who use it.

For example, for different uses such as home, office, hotel, and library, the length of time people stay in it will also be different. Most of the people who use the space are the elderly, children, or adults, and different lighting colors can be matched according to the purpose and object.

It is recommended to choose the color temperature of the light according to the comprehensive consideration of the color and material of the ceiling, wall, and floor of the space. For example, 3000K and 4000K are projected on light-colored wood, dark wood, light-colored stone, dark-colored stone, glossy surface, and matte surface, which brings different feelings to everyone. ​
