Oh, Stan, I little kid's dream come true!

Read my second post under this lamp....

of yours, about me drawing three-ended fluorescent tubes when I was a kid!

That is an amazing lamp.

The arc tube looks complicated to manufacture, no wonder these never became common.

I wonder, what would be the use of such complex, so very expensive lamp concept?
Maybe the high wattages would make some sense, but below 1kW the arc currents for standard, single phase lamp are not yet as large to cause any significant load asymmetry problems to justify such complicated design...

No more selfballasted c***

It should have less flicker than a single phase lamp, that could be a reason, altough not a very big one.

Someone at the Tesla plant had a "dream" like I did, but they had access to the people and machinery to put it into practice, however impractical it may seem when you get right down to the physics of it, electrode losses, surface area to volume effects, special cap, complex working of fused silica, complex control gear etc.
Its just great to see such a concept reach reality, even if only once!

Relative advanced development works are known from Russia, I saw many samples different russian lamps for 3-phase operation, mainly great metal halide types 3000, 6000 watts etc. Unfortunately ask more informations was very difficult, I was forced promise, that any infos are "eyes for only" etc., as big secret. Ans ask any similar lamp was absolutely unpossible, in spite of I hold it in hands.

Why the hell are they so secretive? These days there is no real reason for it. I suppose I'm never really going to find out all the meanings of Russian/Soviet lamp symbols.
