jdevlin he specifically said in his first post that the service was strictly 120/208volt 3 phase. Also a 600volt service would still not explain the 255volts seen at the fixtures. He is missing some element here and consequently so are we, hopefully he will let us know what it is.....

RDK,
So then, the 28 lights were Metal Halide fixtures with a single, large VA, multi-circuit transformer?
Can’t say that I have ever seen a transformer like that before.

I see a broken neutral. Start at the service FROM the meter IN the panel and measure the volts from each side to ground or the EGC - not the neutral. If it's anything but 120 volts - high, or low for that matter, the neutral is broken somewhere before the panel, - maybe the meter perhaps? Then measure the voltage in the panel from neutral to the ground or EGC connection. Voltage from neutral to ground of anything over about 2 volts indicates a busted neutral somewhere. Hope that helps you.
