Normalize Intensity by Area
This will devide the total intensity of the area light by its area. The net effect of this is that no matter the scale of your area light the intensity will remain the same. This non-physical behaviour can be handy when adjusting shadows from area light: shadow softness adjustments (area light size) will not change the overall intensity. From left to right: off (default) and on.
