Thanks, Bob,

that was just I was looking for. At least by combining both (low filter (say
0.1) and finish {phong etc.} I get a nice bright lamp.

Someday I might even understand what phong actually means - but now I have
to leave - some money got to be earned (how else does one get faster FPUs?)

cheers, Justus
