Guide Color Temperature / Light Color
The most common color temperature is neutral white at 4,000K, which provides balanced and neutral lighting and is the ideal choice for the vast majority of purposes, especially in commercial and industrial settings. In addition, at this color temperature of 4,000K, the luminous efficacy is usually the highest, which ensures a very high efficiency.
For a particularly cosy or homely atmosphere (e.g. living areas, guest areas in restaurants), a warm white light of 2,700K may be more suitable.
In certain applications (e.g. vehicle paint shops), on the other hand, daylight white with 5,700K can be the ideal choice. This light color is closest to natural daylight, and is therefore recommended if the illuminated area receives a lot of daylight. This light color is perceived by some people as particularly glaring or even unpleasant.
