Might be it was not clear, but i responded to the later link:
http://a.parsons.edu/~turi/travels/pilchuck/p-d3-demo.jpgThis definitely does not look like (at least finished) lamp...
I know what the XBO (and similar) is about...
This does not look as lamp at all, at least not yet assembled - what i see there are two glass blowing pipes, with (likely) glass-blower on each side and a result of their effort (quite big glass bubble) in the middle...
In fact the lamp is filled with xenon 
I suppose the lamp is really dangerous because the lamp is filled at a relatively high pressure...
