Spacelight Options -Crossposted

Cross posted this to the lighting pros forum:

I own a small studio and I'm thinking about investing in a set of spacelights to have rigged on a permanent basis so clients can come in and have the infinity cove prelit.

I'm trying to choose between the 6KW models and the 2KW models, obviously would be cheaper to use the 2KWs, as I also want to wire them through dimmers.

Question is would I get enough power from the 2KW units? The L-shaped cove floor dimensions are 31.5 ft x 25ft x 15ft to the grid.

I was thinking around 9 lights to cover this area. What's the best solution?

Thanks for any help.
