While creating the lights for the generator room I ran into a very odd issue. The light source of my mesh Light suddenly started to render in black.

Apparently, this behavior happens when you use high Exposure values (20+) combined with a gigantic light source. To avoid this issue you can disable “Normalize”. Normalize ensures that your light renders physically correct. When you disable it you will have to readjust your Exposure value.
