A old GE lighting book.
But what I find interesting is that it lists the rare rectified fluorescent F85T10 bulbs that are the odd 58 inches long.

Interesting catalog, the ballast page shows some 240-280V models.  This must be when 277V commercial wiring practice was just getting started.  At my first job, the factory floor and highbay areas were lit entirely with F96T12/HO fixtures labeled as "265V" (wiring in building was 277/480Y).  The original part of this building was built in the mid-50s, right around the time of that catalog.  Some of the later fixtures (and those in my high school built in 1969) were all labeled 277V.

Yeah I replaced a lot of 277 volt ballasts back in the early 70s.
That 277 can be wicked if you get across it.

One time I lifted a drop in fixture to get to something else and fire shot past my head to the drop in celling frame.
Then the light went out.
Seems the fixture was operating grounded to the ceiling frame using a 120 ballast on 277.
Really nice modification by some one.
