This mod converts all the lighted candles, fires, and most deep dwemer dungeon lamps off. This will make the dungeons much darker so carry torches, spells or whatever to light your way.

Things to in mind:
Falmer will still detect you.
Undead will detect you.
Dwemer machines will detect you.
This does break a bit of lore b/c Drugar typically do keep those crypts lit. However not all drugar crypts are completely dark.

Good additions to this mod are:
Sounds of Skyrim
Darker Dungeons
Rings of Light Enchantment

Known issues;
There were some popping light issues that have been fixed. I will be keeping an eye on comments and continue to update my files as I see issues arise.
