Red T5HO 24W Osram tube tortured in the name of Science!

Gods of fluorescents, forgive me...
Run freezed at 20mA, shot near the electrode, then at the middle of the tube, run-up full current. I believe in the blue-green area I see barium and strontium lines from atoms sputtered off the cathodes of this poor little tube. I feel the pain you suffered, won't do it any more, trust me

I can not see any sign of neon present.
Also you see red phosphor YOX, Y2O3:Eu bearded red line spectrum in a full glory, here not polluted by yellow and orange bands of terbium phosphor.
Spectrum from the green tube also contains a strange peak at ~589nm, it *may be* a line from neon, but usually cathode glow of neon is dominated by slightly shorter 585nm line.
