I see there is a lot of condensed mercury at one tube that being evaporated at the upper lamp. The lamp needs to be run continuously for several tens of hours for that condensed mercury to be evaporated completely.

I"m don't speak English well, and rely on online translating to write in this site.
Please forgive me if my choice of my words looks like offensive, while that isn't my intention.

I only working with the European date format (dd.mm.yyyy).

I lives in Israel, which is a 230-240V, 50hz country.

I ran for an hour it cleared up nicely. But very hot like a incandescent. I won't use this on a regular basis because it's irreplaceable. This tube has never been used

T12/ t17 there's a reason they made heavy magnetic ballasts

Awesome!

I like my lamps thick, my ballasts heavy, and my fixtures tough.

Great find. I love that particular etch!

@veryhighonoutput:
Its normal for VHO's to get hot like that..

Colored Fluorescent's such as F40T12 Red or  Green or Blue are awesome...

Yes especially the t12s and t10s full power but the t17pg not as hot

@veryhighonoutput: Yep, I've noticed that...I guess its because the PG17 has more surface area than a T12 to dissipate heat?
Though I have also noticed that up inside the 'grooves' is a bit hotter than the normal part of the tube...

Right probably because the heat gets concentrated there. Also notice they don't have elongated filament stems like some t12s. Question- ok some t12 vho have elongated filament stems but some old ones have on both ends like this one. But on newer ones only on one end which way technically are you supposed to run them, blue and red coming in or yellow going out? My gess is yellow going out because that's the end which burns out usually? What's your take on this @xmas.

@veryhighonoutput:

That's a good question, and I've wondered myself, but really have no idea. Being AC I wonder if it actually matters?

On a standard magnetic RS, I think its the 'blue side' that's the high-voltage supply (its whichever glows dim with just one lamp installed). The since both lamps are in series the 'yellows' is simply a center-point (filament heating only) and the 'red side' would be the return.
So (if it matters) in a 2-lamp fixture you'd want the lamps so the long-stem filaments were at opposite ends (maybe "electrically" facing the blue??).

Electronic ballast, there would be a difference - some run the 2 lamps in series just like the magnetic version (wiring would be the same there), but some run the 2 lamps in parallel, so with those both the red and blue are individual high-voltage suppies and the yellows are a return.
In that case you'd want the lamps so the long-stem filaments were at the same end ("electrically" facing the blue/red??).

I've seen F32T8 ballasts where they put an arrow under the lamp in the circuit diagram...I assume it has something to do with power flow. Looking at a 4x ballast, it points towards the reds & blues...I guess indicating that's the HV side???
I've never seen it on VHO or HO ballasts (not even modern T5-HO's)

Nice. Was that the one you found at Webster when I was with you?

Hmmmm you have a good point there I do agree with the blue leads coming in and red out would make sense but of course o got mine backward according to your logic but i notice there getting black on the short side already after 2 months on the blue+red. I'm thinking to late just leave for now and see how bad it gets hopeful I can see a eol with these. Anyway I got tons of extras to burn thru.

@veryhighonoutput:
If you've got a bunch, maybe you should setup 2 lights .. purposely doing them opposite eachother to see if they age in different ways?
It'd certainly be an interesting experiment! By 'thought' alone since its AC there should be no difference (note the keyword of "should")....but we all know fluorescents have weird properties and might not play by "should" I assume you will see differences because of that.

@veryhighonoutput I noticed these tubes are completely different when it comes to wattage...GE's PG17 WM is 185w while Sylvania non-SS is 215w...probably confusing the ballasts and difference in colour temperatures.
