Here’s another photo of it. Apparently you can still buy these for a mere £499.00 (36″) or £852.00 (62″). Ouch.
It is described as:
TURBO is built by 12 identical white-sprayed spiral shaped [aluminum] segments whose exterior follow the face of a globe. The inner part of the TURBO light does not blind and the bulb is completely screened.This lamp should be really easy -heh- since it’s made with only one pattern piece. Anyone care to sketch it out for us?"
