OK, I'll let you off the hook since you say ""gases in the tube" , in which case the only
real "gas" is Mercury vapor and only Mercury vapor, with the very very small addition of
some of he emissive material being "gases".

Ok, thank you for your mercy ;-)

Aragon is a true gas and not a vapor.

I do not like the "true gas" term... How do you define it?
Gas is gas :-) There is no true gas or false gas :-))
Almost every matter can change phase from state to liquid and gas
and all of it depends of the temperature. But I guess you call Argon
"a true gas" because it has gas phase in a room temperature, right? :-)

One other thing;

"Plasma is ionized gas :-)))"

Well, that is only half of it. :-)) A Plasma is a stream of positively charged
ions accompanied by about equal proportions of electrons

By "ionized gas" I ment whole gas in state of ionizations.
No ions alone, but with electrons detached from original atoms too :-)
But some of missunderstanding here can be derived from the fact,
that English is my second language, as it was stated correctly
on this ng recently :-))

"I was also correct with the three-phosphors tubes "

I know the guy personnel, that invented all of the tri lamps with the built in reflectors,
Dr. Perry Thrasher, know matter what name is on the bulb. Perry has left the company ,do
to illness and I haven't found out where he went other than California for health reasons.
Me and JB ( John Burleson) had the first sets :-)

Do I understand correctly you are saying design of gas discharge lamps are your profession?
