Light Cognitive Skylight is generated with multiple different types of LEDs combined in a way that the light spectra is very similar to the spectra found in nature. In addition to having the positive spectral qualities of natural light, the visual appearance of the light field is familiar from nature and resembles a view into the sky or horizon. With a dedicated Casambi controller (or other DaliDT8 compatible controller) the light changes over the day just like in nature and the design has been optimized for visual beauty by making the light field dynamic, continuously shifting with infinite colours and infinite resolution.
