Bart Lens needed a large lamp that would create an encircling sphere of light above the conference table in his office, and so began the search. After a long and fruitless quest, he finally decided to design his own mega-light with the “sphere” of a dome.
The result has been likened to a “Calimero” dome, a giant bell, a half-moon…. Everybody seems to have a different name for it.
The sphere is made of ABS plastic (Acrylonitrile Butadiene Styrene), which is cast in a vacuum mould. This is an exceedingly difficult process because of the importance of even weight distribution. The Sphere is suspended from a single steel cable, so the slightest imbalance would cause the dome to tilt. Therefore we pay a lot of attention to the thickness of the materials during the moulding process.
