The small balls of light that from on the tips of the tungsten are simply smaller complex space charge configurations that form where the positive field is most intense due to the fact that a small point creates a region of stronger electric field. I don't think there's anything significant about those balls forming there. I think a good experiment would be to push the current up even higher if possible with a smaller diameter spherical anode. This may allow for the condition where the double layers of the complex space charge configuration collapse down to a single strong double layer near the surface of the anode. This is when the excess heat and transmutations show up. My prediction is that depending on the composition of the anode, some will vaporize completely and others will melt. Those that don't vaporize should show transmutation products. I hope the experimentalist is filming these experiments remotely because I expect copious SR to be emitted in addition to high energy UV light that could damage the eyes and skin.
Northern Lights are not visible on the top. But Hessdalen lights.
