   Since Bob called me out I will offer one suggestion anyway. A neat
 trick for lowering the brightness of a light source with very precise
 control is to wrap it in a sphere with a white filtering pigment. If
 you use rgbf 1 then the brightness of the light coming from inside
 the sphere will be the same. As you gradually lower this the amount
 of light that is allowed to pass is reduced. The accuracy of control
 comes from the amount of decimal places you can use to specify the
 filter value with. Try it, it will work, and then you can tell everybody
 that will listen that you heard it here first.
