I like how they used two circlarc tubes instead of a circline tube ( + = ). I am still curious why they decided to do so.

This was an early attempt to make a round fluorescent fixture where the lamps are semicircle lamps rather than fully round fluorescent lamps like circline fluorescent tubes. These lamps were only produced for a very short time.

If this has two ballasts, it would be better than a single circline. You could turn one off ,use different colours (if the idea of these lasted long enough to make different types), or if one was EOL, the other would still work. I am not sure about the availability of these tubes, even at that time.

As far as I understand, these early fluorescent fixtures typically used 2 ballasts.

These are lamps that are shaped like 180 degree arcs.

How do the sockets work? Are they some sort of press fit thing or do the tubes just sit in them?
