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, 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. Neither of them emit light when wet. Placed Torches will break when contacting water, dropping as an item. Water Candles may be placed underwater, but do not 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. For example, a Chandelier emits much more light than a Water Candle.

The Darkness debuff will decrease the amount of light seen from light sources. The Night Owl Potion's buff will instead increase the lighting seen from light sources.

The area illuminated by a lighting source depends both on the source and the surroundings. For example, a torch emits more light than blinkroot, and blocks and hanging grass block out light.
