Hint: If striving for realism, avoid random tweaking of fade_distance;
if you feel that the light is too dim or too bright, always directly
tweak the light source's brightness instead - even if that means using
apparently insane brightness values to achieve the desired result.

Unless using an area_light with area_illumination on, fade_distance
should typically be roughly equal to the hypothetical radius of whatever
light source you are trying to simulate. So for instance, to simulate a
classic frosted E27 incandescent light bulb, and presuming you're using
a scale of 1m per POV-Ray unit for your scene, a fade_distance of 0.03
would be about the right value.
