hi guys i recently had built a HV power supply out of an old Flyback transformer i had laying around , i think it produces about 10KV ~ 15KV not very sure but it could arc at about ( 6mm in air ) , and as you can see i tried to connect it to a 15W smal light bulb ( the positive terminal is connected to the strange looking rod you see on the left which is just touching the glass ) and i saw that strange effect . ( i don't know but i think its just the highly energetic electrons exiting the glass molecules which causes it to flurecence ) , give me your opinion on what is this ?! and could this apparatus produce xrays ?!
