The EPFL Made a Light 20,000 Times the Luminosity of the Sun

The Swiss Federal Institute of Technology in Lausanne, or the EPFL, has developed a system that generates the luminous flux of over 20,000 suns. Luminous flux is the amount of energy contained in radiating light -- meaning that, while the device is not nearly as hot or powerful as the Sun, its light is far brighter than the Sun's.

The EPFL developed its system in order to test materials under extreme conditions. It consists of 18 spherical light sources placed in concentric circles around a larger half-sphere. This greater sphere measures at two meters in diameter.

The smaller light sources each contain a Xenon bulb and a reflector. Due to the shape of the smaller lights and larger sphere, the light emitted from the EPFL's system gets focused onto a small surface area when activated, creating an extremely powerful luminosity.
