How Big An Environment Can RealTime Lighting Do Before It Slows Down?

Question

My game requires levels with the floors, walls, corridors, buildings, etc all shifting around. Real time lighting on an environment too large may produce lag, slowdown, etc. I need a technique that will produce realistic lighting without slowdown, lag, etc. What is out there?
