Zero, because most lightbulbs are backfilled with nitrogen or argon.  Only
bulbs less than 25W are vacuum and don't give the nice display on a TC
because there's no gas to ionize.  Even then, the light bulb scenario is a
bit of a stretch because making X-rays requires accelerating electrons
through the Efield and having them suddenly stop (which is where the Xrays
come from: bremsstrahlung).  Not going to get many electrons knocked off a
cold cathode, and they're not heading in one particular direction, etc.

Now, a TC operating in a tank is another story entirely....
