Sneaking in the dark

[ptbptb]

Are there sneak bonuses for being in the dark with no light source? Alternatively are there sneak penalties for being in light areas or holding a light source?

 

If not are there any mods that implement them?

Yes, these are already part of the standard vanilla game.

There is one notable exception, though:

while torchlight will give you away, the light from a light spell won't. Apparently light from light spells aren't actual light, but instead some sort of magical infrared that only the caster can see. I made a spell I call "Noonday Sun" which will positively flood a dungeon with light, but the NPC's can't see it, or me as I sneak right past them. Let me sneak by a torch, though, and I'm caught.
