scratch that - the posted scene works with brightness 1. I think I managed to
make the floor semi-transparent on initial tests.

That said, emission media appears to be treated as a brightly lit object, rather
than an emitting object, so the effect is not very strong without a higher
brightness (which presumably might screw up other elements of the scene if you
have additional normal light sources).
