In that case, you can use spot_light that point at the hull's areas that
you want illuminated.
Just remenber that the radius is in degrees, not in units around the
point_at location. (I've seen scenes with that mistake)
You can still use fade_distance and fade_power for those.
As a bonus, you may get some speed improvements as you will save on the
shadow ray tests.
