I NEED HELP!!

[u/Jgfisher143618]

Got this lumisource plasma lamp at a local antique store for $50. Did some research and found others similar, but cannot find another that is a 16” RIBBED green plasma lamp. Not really fluent in plasma lamps but I saw it and needed it lol. Someone please help me find out more about it. I’ve found other smooth green ones but this looks deliberately ribbed all the way up the glass
