In the Creation Kit I can make the lights so bright that everything is white, I literaly need sunglasses on to look at it. But when I go in to the game, my house is still dark, and yes I'm saving it. This is my first experience working with lights in the CK, so maybe I'm doing something wrong, but I don't know what. I've watched several videos on just the lighting aspect of the CK and I still don't know why the lights are so bright in the CK, but in the game it's so dark I need a torch to walk around. Is there some secret light technique I don't know about? This is very frustrating, any help would be greatly appreciated.

Are you enable a mod like RCRN, ELFX or something else? These mods modify the illumination in the game.
