I agree Ghost.
The top of the tower is about 100' across, so of course the logo is about as wide. So I'm thinking probably 10 1500w MH fixtures, with narrow beams. The spacing of the fixtures should be interesting. Not sure if they could be grouped all mostly in the same area, or would have to be spaced evenly( maybe 10' apart) along the rooftop.

I was also told late this afternoon, that " if possible", they would like all of the support structure lit as well. Geez

But that might be much easier actually. I'm thinking fixtures mounted at the base of each leg ( there are about 15 huge supports) all shining straight up.Conduit mounted on the curving concrete curb that rings the tower. Should work fine.
