Thanks for the replies guys. Very useful! Yeah OOO and therefore FCOM already has DLT.
I think I have sorted out my own light. Now I'm after something for NPCs. Let There Be Darkness seems to remove all light that doesn't have a 'real' source ie ambient light? So caves without candles are totally black. That's cool, but it's a bit ridiculous going into a cave full of bandits who are all standing around talking in total darkness
I have found a mod called 'Dungeon Actors have Torches' but that only affects enemy NPCs, and only gives them a 75% chance of having one (seems to me that anyone in a totally dark cave would have a torch). Does anyone know of any mods that give all (non-monster) NPCs in dark places torches? I am at a pretty major disadvantage when I'm the only person lit up in a pitch black cave full of enemies.
@Pseron Wyrd thanks for the suggestion I will give that mod a go, might solve my problem.
