I was trying to build a room in blender and make it bright by setting up a fluorescent lamp right next to one of the walls. So I built a mesh that looked like the lamp and I set up a few lamp objects next to each other in a line so it looks like there would be a shining tube instead a shining spot. But somehow this doesn’t look right.
It looks like the energy on the near wall (left) is less than on the other walls. In my opinion the nearest wall to the lamp should be the brightest.
Does anyone have an idea what I did wrong?
