There should be a date stamp under the ballast.

Pretty, please no more Chinese failure.

Yes i thought of that as i put the workvan in gear to leave.will post that monday
Anyone else have or have seen a fixture like this?
i assume that once there was a cover over the ballast.
or is it possible this was eliminated to reduce steel use during wwII?

Mine are all WWII era and are exposed like this too. They are "back wire" Westinghouse, so nothing but the case is exposed. The fixture is a simple metal "raceway" and a massive porcelain coated reflector. This looks like a very early replacement ballast, as it is designated "for two 100 watt lamps".

so the originals were in the open.
i assumed the reason was to conserve steel in wartime.
nice to learn more about this fixture.

Yessir. That is what i have been told. Interesting that both versions were made around the same time though.

These were made until about 2001 by Power Lighting Products, but the Universal here must have been one of the earlier ones because the 90 watt tubes were introduced soon after the 100s. All the original Westinghouse (back wired) and General Electric (front wired) ballasts I have that came originally in my fixtures are "for two 100 watt lamps". The later replacement ballasts I have by Valmont, Power Lighting and Advance are all "for two 90 or 100 watt lamps". I would LOOOOOOVE to find a huge old stock of 100 watt T17s!

There are two identical F90T17 fixtures in my family's possesion on my dad's side. My grandpa uses one as a desk light and the other is in my great-aunt's garage, formerly my great-grandpa's workbench, though the workbench itself is long gone. I think I may have mentioned these before. They have egg crate louvers on them. they're two lamp units and have enclosed ballasts. The reflector/louver assembly along weighs a good 20-30 pounds. Thick steel! I have no clue how much the top section weighs but it's probably a ton too. When i had opened up the fixture I didn't pay much attention to the ballast itself but I recall a couple of loose black wires inside. I THINK in the ballast might hae had a tan label so maybe a GE ballast. The label didn't take up the whole surface of the ballast like this one does.

Yeah I could imagine a collector's face if he or she were to come accross a sealed case of 100W T17s! I'd like to just be able to get some lamps cheap. I know they're nearly impossible to find cheap but I'm not really up for paying the price that those lamps sell for. My grandpa has two new F90T17 GEs bubblewrapped up in between the joists in his basement. Those two tubes would get the fixtures going (his only has one lamps and the other has one EOL tube) so I guess I would have to be conservative with the hours on the fixtures lol.
