equilumen is a lamp created by mischer’traxler. It plays with the concepts of balance, movement, and time. A long rod carries a glass sphere on each end. When the installation is in total balance, both spheres have the same brightness level, sharing the lamp’s power equally. Once somebody pulls one end of the lamp into the lower position, that lamp lights up more, while the one at the higher end dims. The user can therefore change the distribution of lighting according to his/her current needs.
