The radius of the habitat is close to 300 meters. The metal rods are 2 
meters thick in both cases.

Segmenting the light source would create strange shadows on the 
interior. Not sure what you mean about the pavement and 6 sections. I 
would like to make the light source more yellow, but haven't figured out 
how. Here's the LightSys code I use:

#local Lightsys_Scene_Scale	= Meters * 100;			// 1 = 1cm?
#local light_lumens		= 2;					// float
#local light_temp		= Daylight(6100);			// float
#local light_color		= Light_Color(light_temp, light_lumens);
