How wide of a light spread can 1000 watt hps provide in a mondo reflector?

I am planning a room where I am going to use 4 1000 watt ballasts in a mondo air cooled reflector. Assuming my plants are going to be put into 12/12 when they are about 14ish inches tall, what kind of a light spread or lighting footprint can each light provide? They are going to be arranged so that each light covers a quarter of the growroom.

Any input would be greatly appreciated.

4 ft by 4 ft each why not buy a light mover ...search widow makers gallery

I was thinking of getting light movers but was worried that it would be a pain considering that the light will be air cooled with those slinky type ducts. How big of an issue do you think that is?
