Light sources

"Light" redirects here. For the modifier for melee weapons, see Modifiers.

Torches and Glowsticks can be a light for you in dark places when all other lights go out. Torches won't work underwater, but Glowsticks will.

— A loading screen tip

Light sources are items that produce light. Some are brighter than others and produce varying colors of light. Note that several weapons and armor types also generate light, but are not listed on this page.

Primary light sources

These items are intended to provide light as a primary function.

Portable

The following items are portable light sources that can provide light while being carried. Torches and Candles may also be placed as Furniture, and Glowsticks can be thrown. Water Candles will increase enemy spawn rates in the vicinity, while Peace Candles will do the opposite.
