Let me explain a little more. This is a 10,000 sq ft warehouse that i will be building these rooms. Client will be able to rent either the white or the green room simultaneously. I was thing of having fixed light in each room and we can still add addition hanging light on the grid if clients need more lights for project. I see everyone is say use the kino flo lights. I was looking at the kino flo light and if i put 8 300w that would be $6,000 per room. Do you think 8 of them will adequately light 30x30x15 room?
