What if you could add a skylight to your basement or any other room that could use a slice of sunlight? Thanks to CoeLux, that’s now a possibility. The award-winning lighting system uses nanotechnology to reproduce the appearance of sunlight in a way that’s amazingly realistic. That’s right — what you’re seeing in these images is artificial light.

The Italian company of the same name offers three versions of the fixtures based on the angle at which the LED light hits the room. The CoeLux 60 mimics the direct sunlight found in the tropics; the 45 replicates the balanced light of the Mediterranean sun; and the 30 is a wall “window” that produces the warmer, more lateral light found in Nordic countries.

CoeLux is a research project spun off from Insubria University in Como, Italy, and funded by the European Union. “Science and technology, like art, allow us to reproduce reality, putting on stage the laws that we believe are relevant in nature,” says founder and CEO Paolo Di Trapani, a professor at the university.

In addition to brightening homes, CoeLux has several applications in commercial architecture; imagine the possibilities in parking garages, subway systems, museums, hospitals, apartment buildings and shopping malls, for example. Which room in your home would you like to lighten up?
