Light sources

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.

=== Blocks ===
Any corresponding walls will also give off light, except for Offline Gemspark Walls. This may not be noticeable if both are used in the same area, as the blocks tend to outshine the walls.
