Weird, I did not see the recipe for the Redstone OFF one in NEI. And yes ofcourse the ON one is just a different state Block, but I wanted to make sure. 
And I guess the lack of saying anything about Spectral Dew confirms that its basically like Water but not boiling away in the Nether? XD
Edit: Okay so I fixed the wrong Redstone Lantern Recipe that I added then, It was using a Redstone Lamp instead of a Glowstone Lantern + Redstone. And considering there is a LOT of OreDict Stuff I do to make Mods compatible with each other and GT (and in this case to make the Nether more able to make Bases in), I ofcourse need to continue doing stuff like that. ^^
Btw just as a random info, I also added Red Clay to the Nether just to get access to Pottery and Bricks down there. I used Red Clay for that because it fits best to Netherrack.
