How many watts is 4000K

It cannot be calculated. 4000K refers to the color temperature, which means color. There is no direct conversion relationship between color temperature and power (W), so it cannot be calculated.

Color temperature is a physical quantity used to define the color of a light source in lighting optics. That is, when a black body is heated to a temperature and the color of the light it emits is the same as the color of the light emitted by a certain light source, the temperature at which the black body is heated is called the color temperature of the light source, or color temperature for short. Its unit is "K" (Kelvin temperature unit). Color temperature (colo(u)r temperature) is a characteristic of visible light that has important applications in photography, video recording, publishing and other fields. The color temperature of a light source is determined by comparing its color with that of a theoretical thermal black body radiator. The Kelvin temperature when the thermal black body radiator matches the color of the light source is the color temperature of that light source, which is directly related to Planck's black body radiation law.

What color is 4000K?

Color temperature 4000K is warm white. According to my country's "National Standard for Lighting Lamps", 4000-5700K is warm white. The color temperature of lights in large shopping malls and hotels is basically around 4000K. 4000 is generally called cold white, and 4000-5000 (neutral white) is good for home use.

What does the color temperature of T5 tube 4000K mean?

The color temperature of the T5 tube is 4000K, which means that based on the absolute black body, the color temperature of the T5 tube when it is lit is 4000 Kelvin.

2. T5 lamp is a kind of fluorescent lamp, also known as fluorescent lamp, light tube, fluorescent tube, with a diameter of five-eighths of an inch and a tube diameter of about 16 mm. It is a kind of low-pressure gas discharge lamp.
