Hey Rob,

Check out http://www.sunlightsupply.com/hortic...ballasts.shtml

Sunlight supply offers a twin 250W MH/HPS unit.



If I read that right, the ballast is a dual ballast, but designed to
run two, 250W independent fixtures on some sort of light mover or rail.
Although I did find a dual 500W fixture from my own local shop (and I
recommend them highly). I learn something new every day...
