Yeah I think the darkness needs to be toned down a little. Even during the daytime I can barely make out what I am looking at. I was under the impression that it would just make the darkness darker, but it seems to make everything dark all the time. Don't really have an issue if it was intended to be dark all the time, but having it be not heavy enough to make you have to squint all the time would be great

So does this actually affect the lighting values or is it just darker for the player like in some other mods?

unless i have some kinda mod conflict the curse does affect lamps otherwise they should be outputting 50% lighting. as per screenshot i'm only getting 45%

So far the lighting has been that crazy for me when I have had torches and such in place. its certainly darker than normal but not to the point I can see when I have got a light source set up

If you go to storyteller settings, then close it so the curse screen pops up, quickly toggle it on and off again. My places that should have lit started working properly. You'll have to do it every time you load the save until that's patched.
