"If you say there is ionization, this is what I was saying before :-))"

But the gas in question was Argon, so you are still incorrect, at least for Argon :-))

I was not talking about Argon but about "gases in the tube" :-))
But I admit, I had no idea about the relation between pressure and output.
I was also correct with the three-phosphors tubes change color over time
as you stated each kind of phosphor has a different burn-out rate, so if
over time, let's say, 2 of 3 phosphors will burn out you will got one
phosphor tube after a couple of months, not three-phosphors tube like new one.
And overdriving any tube will dresticaly shorten its life - that is the fact.
So if 6-12 months rule apply to all "nominaly" driven tubes, those overdriven
will change over time much faster and need to be replaced more often to keep
their light-output parameters. I guess we both agree in that matter.
And this was the point of the main conversation, not the nature of fluoroscence :-)

"After all, I was not so wrong :-))))) LOL!"

OK, I'm going to let you slide buy today.........
so now I will go pick on King Marc for you ;-)

Thank you :-))
