bulidin a new room

hey guys i have a new room to build has bunch of stuff in it so measurements are rough but looks like is about 8 x 15 ft might be as big as 10 x 17 but thinking closer to 8x15 so i was thinking 2 600 hps air cooled wanted to go digital but those are too expensive for me right now rooms already painted white and insulated and wired so so u guys think that the 2 600s would be enought light

bump was looking at how many lumen/per square foot looks like im need alot more but any other imput would be apprciated
