<p>The color mixing of lamps with white light color - mostly warm white and daylight white - is especially used for adaptive illumination. Warm white light color has a higher sprectrum of red color like dawn and dusk lighting, whereas daylight white light color has a higher spectrum of blue light like noon lighting. In this way the light conditions of a daily course can be simulated, where especially the excellent color rendering properties of the used lights for all lighting conditions will remain.</p>
