I was under the impression that most light bulbs "contained" only a hard 
vacuum.  And yes, with any voltage much over a few tens of kV, in a vacuum 
it ain't difficult at all to generate X-rays.  And given the voltage of a Tesla 
coil, they aren't going to be soft, either, although the dose-rate, 
determined by the current, won't be much.  The tungsten of which bulb 
filaments are made is just dandy for producing X-rays.

Tesla himself had a few "single electrode" x-ray tube designs which ran on
