So I picked up a 400watt Sun System reflective shield and a hortilux bulb however it did not come with a ballast. I like the slinder style ballast but I am confused if it will work with the sun system I have. The plug has 2 circle posts and a normal outlet prong. The ballast I am looking at it the correct holes however one of the circles is flat on the bottom. Does anyone know if it will work or do I have to go with an actual Sun System ballast, the big boxy white ones?
