Thanks for your comments.



Those lights were originally modeled as both a light source and emitting media
for an earlier scene.  However this scene has many more of them and rendering
ground to a halt, so I am currently only using emitting media for them.  I am
playing with how bright to make them, and the radiosity settings have a big
influence on that.  I will compare my media to yours when I get back to it.
