The Kelvin scale is used widely in science, particularly in the physical sciences. An old-fashioned incandescent bulb, which puts out yellowish light, has a color temperature of about 3, K.
Put another way, this means its yellowish spectrum closely resembles what a hot object at a 3, K temperature would naturally radiate. Many newly available LED lights fall within this range or go even higher.
That is a valuable common reference because, for a precise formulation of water at a specific pressure, the triple point always occurs at exactly the same temperature: Extrapolating from the water triple-point temperature to very high or very low temperatures is problematic; so, by international agreement, 21 other defining points are specified, ranging from the freezing point of helium to the freezing point of copper.
However, the kelvin has been redefined in terms of the Boltzmann constant, which relates the amount of thermodynamic energy in a substance to its temperature. Such lamps can often be found in the living room, dining area or any other room where you want to relax. Natural white light creates an objective, positive atmosphere. It is therefore frequently used in kitchens, bathrooms and corridors.
This color temperature range is also suitable for illuminating offices. Cold white is also known as daylight white. It corresponds to daylight during lunchtime. Cold white light promotes concentration and is therefore very suitable for workplaces where creativity and a high level of attention are required. On the one hand there are dimmable LED illuminants , which lower their color temperature during dimming. This not only makes the light darker, but also warmer in color. The result is a very cozy lighting atmosphere.
For example, you can set a warm white light color to relax. If you want to concentrate on something, you can switch to a cold white color.
