I am planning on removing the current lights in hopes to make something better.

currently the lights are a part of the same object as the ceiling.
my modeler dosen't work all that well with materials so i group the object by the desired material then assign materials either in the uv mapper or in poser. so for example there is a material zone and a group for the ceiling, the light frame and the light.

the lights are not embedded in the object in so much as if they are removed from the ceiling (or floor) it will not create a hole in the mesh.

when i create new lights, i might keep them as a separate prop that loads in place. and perhaps even have a single light prop/object that can be duplicated in programs that take advantage of that technique.

my lighting in my test scenes consists of two lights. one IBL and one infinite pointing straight down.
