Probably 1960s interference suppression capacitor. It has three wires coming into it. Some of them were burnt. Fixtures were for 80 W 1500 mm T12. May these contain PCBs? There was 58 W T8 lamps on these fixtures, despite they were rated for 80 W.

There was the other model capacitor with metal sleeve. The supply wiring is newer than fixture.

Ok. Wiring seems to be newer, because it uses wire colors used beetween 1974-2002 in Finland.

Too many things are secret. Only open information can really preserve old technology.

I like fluorescent and other conventional lighting and old electronic equipment. Today's things are not made to last.

For some reasons some 1970 fixtures has blue neutral wires, even the supply neutral is older grey.

Ok. Maybe electricians were using remaining old cables then.

Somewhat similar. It was for single 80 W 1500 mm T12 tube.

This type is banned nowadays by energy efficiency regulations. 20, 40 and 65 watt tubes are still available for rapid start circuits.
