Tin Sconce
1) Cheap, not inexpensive, but cheap. 2x tin, 1 root, 1 elm, 1 coal, lvl 9 artisan cheap. If you can't afford to buy raws on broker for a couple silver, then hit your newbie zone for them & sell off the leaded loams you harvest to tinkers.
2) Real light.
3) Simple design fits with most decors.
4) Small enough to be hidden to give light to unlit lamps. I stole the idea of another designer & tuck mine inside my bronze sconces to get light effect. You could also easily use this behind another object to create indirect accent lighting.
