The one on the left is cleared out Russian Osram F18T8 tube. On the right is **the picture was given for me to use by the very nice gallery user Dor, I don't own that tube, he owns it, together with the copyright grounds for the two pictures on the right side** Russian Osram Germicidal F30T8 tube. For me, both cathodes are looking the same way. The construction is the same, the crappy singly-coil filament is the same, the cathode guard is the same. The only difference for me is the Germicidal one uses higher glass cathode stem compared to the normal one. I don't know if it is just me, or do you guys see it too. Tell me your opinion in the comments below. Thanks!
