Presuming the area light is supposed to simulate a structure somewhat akin to a
long cylinder, I would set fade_distance to the radius of that structure; to get
the proper behaviour along the length of the area light, I would suggest using
area_illumination.

For realism, fade_power should always be 2. Note that you may have to
significantly increase the light source's brightness.
