The video herein is a response to several great comments on my earlier video testing a magnetron as an x-ray generating device. In this video, a series if different lightbulbs are connected to a high voltage power supply to evaluate for x-ray production. These bulbs include a neon flicker-flame bulb, a regular incandescent bulb, and a vintage incandescent lightbulb. Stay tuned to see what happens. The results are very interesting. 
Please note that the old style vintage bulbs did not contain argon, and instead used a hard vacuum to prevent the filament from burning up. The presence of a hard vacuum as we have seen an earlier videos results in x-ray production when a high voltage is placed across such a tube or bulb.
******Spoiler*****: the output from this bulb was insane and my tube Geiger was reading greater than 100 mR/h at a distance of 4 feet. Using inverse square law, this comes to 1.6 R/ h at 1 foot distance. That is a very unsafe level. Also it’s diffuse and not directional. Please don’t try this at home unless you have lead shielding.
