Kelvin

Kelvin (abbreviated as K) is a unit of temperature in which theColor Temperature is specified for a light fixture. The lower the number, the warmer the light. A candle, for example, has 1,500 Kelvin and therefore gives off a very warm light, awarm white The color temperature of a light source ranges from approximately 2,700 Kelvin to 3,300 Kelvin. Neutral-white light falls within the Kelvin spectrum from 3,300 Kelvin to 5,300 Kelvin, and cool-white or daylight-white light has a value above 5,300 Kelvin.

What makes the Kelvin temperature scale unique is that it is based on what is known as absolute zero. The Celsius scale, on the other hand, is based on the freezing point of water; thus, 0 Kelvin is equal to -273.15 degrees Celsius. Negative values exist only in degrees Celsius; the Kelvin scale, on the other hand, consists solely of positive values. However, the temperature increments are identical on both scales.

In the field of lighting, color temperature—and thus the Kelvin value—is therefore interesting and important because, depending onLight Color It makes us feel differently and creates a different atmosphere. For example, cool-white light with a high Kelvin temperature feels very cool and is therefore well-suited for home offices. Warm-white light with a low Kelvin temperature is more commonly used in living rooms or bedrooms because it has a very cozy effect on us.
