Light sources

Light Sources are items (mostly furniture) that produce light.

Usage
Torches, can be placed on the top or sides of any solid block (including tree trunks, but excluding Wood Platforms) and removed by right-clicking or hammering.

Candles and Water Candles can only be placed on top of Wooden Platforms or Tables or Workbenches. They also can be removed by right-clicking or hammering.

Torches and Candles emit light of equal brightness while in an active Inventory slot, however, neither of them emits light when wet. Placed Torches will break when contacting water, dropping as an item. Water Candles may be placed underwater, but do no emit light when held and wet.

Chandeliers and Chain Lanterns can only be hung from solid ceilings (not Wooden Platforms) and only if there is enough space (3x3 for chandelier and 1x2 for lantern). They aren't affected by water and can only be removed with a hammer.

Lighting Differences
Lighting may vary depending on the Light Source used and certain buffs. For example, a Chandelier gives off way more light then a torch and light generated by placed Water Candles and Chain Lanterns are perceptibly duller than from any other source.

When it comes to buffs, Darkness will decrease all lighting seen from torches while underground, and decrease day and night vision. Night Owl Potion will instead increase the lighting seen from torches and increase day/night vision.
