Ok, it isn’t a real sky light but according to its inventors your eyes and body won’t know the difference.

The new system was introduced at a recent innovation convention. Commissioned by the COELUX EU-this project recreates the physical and optical effects of natural light indoors by simulating the diffusion and transmission of sunlight through the atmosphere.

Using energy-saving LEDs (light-emitting diodes) the inventors claim it can reproduce the same spectrum of light as sunlight. They also boast it has a sophisticated optical system to create a sensation of distance between the simulated sky and the ‘sun’.

Perhaps this invention could spell the end of seasonal effective disorder for many someday.
