This is great for creating standard emg arrangements, very simple and much quicker that creating emg scenes as you would have to in 4.13. What is missing though is the ability to calculate emergency lighting levels on other calculation surfaces created as part of the maintained lighting scene. For example in plant rooms where calculation surfaces have been created for mechanical valve arrangements or electrical switch panels there is no way that I can see to have the same calculation surface give a result for the emergency lighting scene.
