It just isn't very fun for me. I don't enjoy squinting into my monitor. It gives me a headache.
This. Never been a big fan of "Dark Darkness" mods. I actually find it dark enough out of the box - light enough to be able to appreciate the architecture/etc, but there's still places where light spells/torches are useful to pick out details (like loot in dark corners).
Of course, it also depends on the calibration & color profile of your monitor or TV. The default game doesn't look quite the same to everyone.
