@bobdvd - the link to the underground history pics had a remark that confirms what I seemed to remember - that they emit heaps of UV and it's not good to look at them for long.

These guys are a lot more complicated than I realized. I found this quirky video with an in-depth explanation of how they work: http://www.youtube.com/watch?v=6Oq9VC94vbw

After looking at videos of these tubes in operation, I am amazed at the erratic flickering of the arc.  I would guess that the output is pretty noisy!

That's an Arc Rectifier! I doscovered them in 2010 and was instantly in love. They glow a wonderful blue green!

Here's my article from back then.

I've seen pictures of them in abandoned buildings:

Rectifier?

Given the specs and the use case, I'd say a rectifier. The tube looks very simple, but I can't see the cathode or anode. What's with all the "empty" space?
