For EZDome in P12, you can enter the Material Room and change the intensity of its emission. I found that the SuperFly setup is very simple. One word of caution, I caught a glitch in EZDome that will influence the type of light emitted on the scene. During setup, if you decide to change the scene on the domes, I found that the inner dome did not readily change along with the outer dome. You can't catch it in preview, only in SuperFly render. The only remedy is to enter the Material Room and change the connections.
