Cool find Aaron! A 277Vac F20T12 ballast
Is that a step up transformer or another ballast using the 277V as an output?
Also wow 20W ballast/transformer losses

Yep a step up trans..actually run backwards..it's supposed to go 277-120 but works fine. its made by indy lighting .kinda lossy but it's full power and has a nice hum..I just put it together and made a plate covering the big knockout.the ballast cover has to be screwed on at the transformer end since it's a bit too big but it works!

Yeah, the step-up trans will also add losses. I have a 36v transformer from a golf cart battery charger I want to use in a 'boost' configuration to make a 20a 277v circuit whenever I get time. (240v in series with 36v output will make ~277v)

Do you know where these ballasts were originally used? Can't be too many applications for these.

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