oddly enough, the original ballast according to the fixture label was 277V but these were both wired for 240V with a red wire and a white wire. are the two voltages convertable among each other in some way?
BTW, see my handprint on the M-400A2? the paint is all powdery. I need to repaint them.
the caps are too rusty to read. i remember the fixtures all being HPS, MV, and MH so it must've been sometime in the mid-2000s that they were retrofitted.

Also any dates on them, that might clue in as to when they were retrofitted.
