Invented in 1982, their unique patented construction and design have won these large lightweight softboxes worldwide popularity. A lightweight die cast rigid central mounting for the flashhead inside the unit, which places the flashtube at the point of focus.

The optical result is a light source, which is so even at the diffuser surface, that many famous photographers use the Octa as a single light source for portrait photography. In the U.S.A. it is often referred to as "The Beauty Light". This exceptional softness of the light has sold many of thousands of units, adapted to other flash systems, which do not have equivalent light sources.
