Making a level entirely out of dynamic lights is a very very bad idea. If your light doesn't NEED to be a dynamic light, then it would be wise to make it a static light.
The reasoning behind this lies in a very well documented and well known limitation with DirectX lights (which is what the dynamic lights in FPSC run off of). The limitation keeps you from having more than 7-8 dynamic lights active at one given time, and although this is very well handled in FPSC, if you were to try to have too many dynamic lights on screen at the same time, then some of them will not function at all.
