I kinda like the dark, atmospheric lighting in some places, but it's a pain in the ass when you're searching for items that are easily overlooked. There are plenty of items that provide light and night eye effects but i can't recall any that are as powerful as you suggest. It sounds like the perfect time to get some enchanting practice!

P.S. If you're gonna enchant your own, go for a night eye spell rather than a light spell. Much more practical.
