I really don't like the idea of stepping voltage up to 480V just for a few light fixtures. I undstand how you feel though. You have to pipe them in, pull wire, set boxes, provide a way of turning them on and off, probably add a breaker in a panel somewhere, and hang the fixtures. The question is, can you buy a 3 phase 208/480 Volt transformer for less than the 7 balasts? I don't know.....

You still have to buy the transformer, install it, pipe into it and out of it.....I wouldn't. I'd buy some ballasts.
That 208V ain't broke, don't go fixin' it,
