It is the former.  The lights are actually stuffed up in holes
differenced in the ceiling.  It is caused by the angle at which some of
them enter (I had a hard time making a sample scene to reproduce the
problem with because not every light source triggered it).

I knew it wasn't the latter as I always make sure my unions and
differences extend past the point of just touching.
