seeing as how every dwarf drops both eyes and resin, how is it easier? Guck is a limited resource, and I can't see ever making a green torch, but I have maybe 20 wall sconce and resin still piles up like mad. The blue is pretty -- if they add blue wall hanger, I will be all over that.

Don't forget the Circlet! I know it's not a resource but.. y'know. It's a great light.

Dragon Eggs also glow

Yellow mushrooms, surtling cores, poison and frost meads among other things work for me.

the turnip seems like the brightest small light. I suspect it is a limited time only item, so place them while you can.
blue torch is blue. it isn't terribly bright. green torch is green, also not all that bright.
crystal walls or even open air windows let in a lot of light in the daytime and more than you would think at night.
moder tears are fairly bright but won't sit on item stands.

What about the lighting effect when you combine all three standing iron torches next to each other to get a 'white' light? It takes more resources, but I'd be curious if the 'white' light actually feels brighter then the other lighting options.

I believe dragon tears emit a bright blue light since it is a boss drop. The only drawback is that you can't mount it.
So you firstly need to make sure there is a workbench in range of the place that you want to drop it so that it does not despawn. And then you ideally want to make sure that the place that you drop it is somewhere where you are unlikely to pick it back up.

A self-made lantern frame or some kind of wide pit would help in making their placement look decorative.
