3.5' x 7.5' grow area, which lights?

Budget and monthly bill is somewhat an issue, though I'm sure it can be worked with. Would two 600 watt hps lights work flowering 50 sites (SOG) in a 3.5 x 7.5 area?
My setup is practically an aeroflo 60 site but as 50 sites instead. I'm trying to find the best alternative. Maybe a light rail for each light? I know thats sort of pushing it, but I'm sure someone has done it before.
Just curious

Sorry I thought this didn't post so I reposted it in the regular aero section, i'm not too sure how to delete this one if anyone can tell me how that would be ballin'.

Dolladime69sugashane: in a confined area you're not likely to be commercially viable so I have to ask you what ventilation you have? MH, HID and some other lighting systems people seem to be in love with now a days usually require some serious cooling and the utility cost is a serous issue. Have you considered a rack of T'5's? You could get one that fits in that area and it wouldn't require a lot of cooling because they don't burn as hot as other lighting systems. You also won't have to sell a kidney to pay the electric bill. They run cheap. HSA

That is a great point you bring, now i'm actually going to read up a lot more on that, The room is a bigger than the aero unit (i could probably fit two - sectioned off) but i'm working on one at the moment. Ventilation, I don't have set up at the moment because i'm just waiting to figure out the initial set up so i can run exhaust and intake according to the lighting and what not. Geez, now you have my mind on over drive lol. Maybe i could set up a racks near the bottom and top/sides of the plants then a 600 watt hps on a rail (just for that potential) man, I don't know haha I'm going to go tear apart RIU now for more on t5's for flowering. thank you HSA
