Vienna design studio Mischer’Traxler launched a lamp named Equilumen.
Two identical spherical light sources are connected with a long rod, and placed on the both ends. When the entire device is in equilibrium, two spherical light sources will simultaneously emit light, and has the same light intensity.
If this balance is broken, the lower lamp lights up more, at the same time the other end gets dimmed.
