I use lights like:

#declare Pos = <10, 10, -10>
#declare Amplitude = 15;
#declare Size1 = 2;
#declare Size2 = 3;

light_source { Pos
  <1,1,1> * Amplitude
  area_light Size1 Size2, 4, 4
  fade_power 2
  fade_distance sqrt(Size1*Size2)
}

and control the brightness with the Amplitude. This seems to be a common way
to do it.
