Chain Lantern

Chain Lanterns are small hanging lights found only in Dungeons, and cannot be crafted. They are placed like Chandeliers but take up much less space, which makes them ideal for small rooms or passages. Since many of them may appear near the entrance or above ground level, it is possible to obtain them without having to kill Skeletron to gain access to the Dungeon.

Although they give off light, they are not considered 'light sources' by game mechanics, so they can't be used to create rooms, and won't affect the growth of glowing mushrooms.
