thank you for your response,I attached two radiance files, unfortunately i
couldn't find where i can send my files from the site.
the difference is 100% or some times more,i attached radiance files,the
light shelf i use has 90% reflectance that should cause increase of
illuminance in the back of the room, but it in rad1 file it is decreased,
and in the rad 2 file it is increased.
I hope these discription would be enough
