I'm fairly new to this and am trying to find a good mod that makes nights a good deal darker. I have CoT, and it has a customizable darkness effect, but I shied away from turning the darkness up too much because of the dimness effect it has on campfires and other light sources( thanks to gopher for pointing that out in one of his vids). Are there any good mods that can make darker nights that don't have this "sunglasses" effect on light sources? Also, which ENB mods have the best dark nights? I may try one of them out in the near future.

Have you considered using the CoT dark nights along with mods that brighten fires and torches? That works for me.
