User blog:KickMeElmo/Light-producing backgrounds and blocks

I'm looking to figure out which blocks, backgrounds, or even bars will produce light when placed. There are a few places where placing torches is less desirable (mostly in material farms and for aesthetic purposes). Does anyone know a few offhand? I'll be setting up an updated image of all material types at some point, but I don't really have time to do that right now, so any help is appreciated.
