Coelux, a design group based in Italy, has developed an incredible technology that emulates the visual and physical properties of sunlight. The engineers built and designed a complex optical system using the concept of Rayleigh Scattering, which describes the dynamics of sunlight in the atmosphere. The light quality is so similar to that of sunlight that most people couldn't tell the difference! The units have only been installed in a few locations in Italy, but the company plans on finding applications within markets that place high value in access to daylight architecture and health & wellness.
