point light trouble and rendering

I’m working on a project where a recreate the moonbase alpha from space 1999. The interiors are very bright. And all the roof are supposed to be individual lights.

Because of the design of the interior i’ve choose to not modelise rooms but only one wall segment and so and duplicated them.

But i have trouble with the lights. I’ve made a blueprint unsing one segment of the roof and and added a static point light. In the beginning i got no problems at all. But now the maps is quite big, my computer crash while building static lights.

So my question is, how can i light the maps better while keeping the modular design. Is it possible to script a point light to have only one by room ?
