There are already lamps and bulbs that can somewhat emulate sunlight, but CoeLux is on another level. Assuming it’s the real deal, that is. Founded by University of Insubria associate professor Paolo Di Trapani, the company’s eponymous lighting looks exactly like a sunny blue sky. The company claims that the images below (along with the rest of the images on its website) are “real and unretouched.”
According to World Architecture News, CoeLux has three key components: LEDs that reproduce sunlight, an optical system that creates distance between the fake sky and the fake sun, and nanomaterials that induce Rayleigh scattering, the phenomenon responsible for our planet’s blue skies and wonderful sunsets. The device is then installed in a “false ceiling and window system” to enhance the illusion. Currently, CoeLux has three types of lighting that provide light at different angles.
