What is the color temperature of 6500k?

The color temperature of 6500k is cold white light.

6500K indicates that the color temperature of the bulb is cold white. To put it bluntly, the light of this lamp is white light. The color of the light emitted by the lamp is the color temperature marked on the lamp, and the unit is K. The lower the value, the yellower the color of the light. The higher the value, the whiter the color of the light. Around 3000K is called warm white, close to the sun color, and around 6000K is called positive white or cold white, which looks more solemn. It can also be said that 3000K is yellow; 4000K is white; 6000K local white light.

A light bulb can have multiple color temperature choices, but a light bulb can only use one color temperature. 6500K refers to the color temperature of the lamp. The ideal blackbody heats up in a family, and its luminous color is expressed by its heating temperature, which is called "color temperature". The color temperature of 6500k, also called cold white light, is a relatively bright light. When the color temperature is 3000k/4500k, it belongs to warm color system and turns yellow.

What is color temperature?

Color temperature is a unit of measurement, indicating the color components contained in light. The peak of wide color temperature is also called "color temperature of light source", which describes the spectral components of thermal radiation light source. The color temperature can be expressed by absolute temperature k (Kelvin).

The written definition of color temperature "refers to the temperature of the black body when the radiation of the light source is exactly the same as that of the absolute black body in the visible region". In other words, "when a light source emits light, it produces a set of spectra. If a pure black object wants to emit the same spectrum, it needs to reach a certain temperature, and this temperature is the color temperature of the light source. "

Remember a rule about color temperature, the higher the color temperature, the colder the color emitted by the light source; The lower the color temperature, the warmer the color emitted by the light source.
