This is a render with 2 lumens:

This is a render with 3 lumens:

Here is the code I am using.

// -------------------------------------------------------------
// Lights
// Sun is not at realistic distance and is not an area light like it
should be.
// Could use "sunpos.inc" here too to determine a correct position and
angle.
#declare light_source_lumens = 3; // float
#declare light_source_temp = Daylight(6100); // float
#declare light_source_color =
Light_Color(light_source_temp,light_source_lumens); // float
#declare light_source_location = vrotate(<0,0,-1000000000>,
<-060,-060,+000>); // needs to be far enough above the clouds to cast
shadows
light_source
{
light_source_location
srgb light_source_color
parallel
point_at <0,0,0>
}
