if your room is that small just get one 600 watt or a 1000, personally i think the 1000 is a little over kill. hell you could even by a conversion bulb and buy just the one light system. say you buy the 1000 watt for $300 bucks you can get a conversion bulb for about $100 that a total of $400, its going to cost you that much just to buy 2- 400 watts anyways.
