First off,your light should be at the center of the cylinder <11,0,0>
Otherwise the code seems correct. But:
POV's area lights only affect shadows, so the lighting on nearby walls still
looks like that of a point light. Perhaps the best solution would be to
create a string of point lights instead of the area light. They need to be
fairly dense to give soft shadows, but at least the lighting is correct.
