Hey John
Would it make any sense to use a single 10 ton unit and set it up to do zoning? I'm assuming this is a feature that will allow cold air to be directed where its needed, right? and price wise would it be cheaper too?
Zoning is the feature that allows air to cool each room as needed. If you want to do a single unit and do flip flop on ur lights then you could most likely get by with a single 7.5 ton unit that is zoned properly will do the trick. This will give you 5 tons for room with lights on and 2.5 tons for room with the lights out. Keep in mind you will want 3 phase power to power up the outdoor unit for anything bigger than 5 tons.
