Why do you want to see trough over 128 boxes?
If it's to increase the colouring, you should be better to use this:
interior{fade_color Red fade_distance 1}
If you reduce the fade_distance, the colouring will increase.
By the way, the ball (sphere) don't emit light, it's normaly lighted by a 
light_source.
The only way that an object can effectively emit light, is in a radiosity scene 
if the object have a non-zero ambient value.
