I think that usually calls for increasing the filter instead of lowering it,
then using high ambient or making the bulbs pigment more than 1 (rgbf<2,2,2,.9>
?) for it to show.  If I understand right.

| Hello. I need some help to finish the hallway scene I'm working on. Here's
| the situation: I need for the lamps to cast light, and yet be
| self-shadowing. I tried using looks_like, but they don't self-shadow. I
| tried with light_groups, and got no where, since the lamp needs to be lit
| from an external source to show up. I tried using rgbf <1,1,1,.1> and very
| bright lights, but I get some strange banding on the bottom of the lightbulb
| that no amount of max_trace_level seems to cure. What can I do? I want to
| put lights in the center of the lightbulbs, but for the bulbs to be opaque
| (non-transparent), slightly reflective and self-shadowing. Help. TIA
