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.

And even before 1.2, the player him/herself generated a small amount of light.

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.

Furniture
The following provide light primarily as placed background Furniture.

Novelty lights
These placeable items provide a low amount of colored light, and are primarily intended as decoration, rather than providing functional light.

Light Pets
These items summon a secondary floating light-emitting character that follows the player. They are infinitely reusable, cost no mana, remain indefinitely, and work in liquids. Light Pets have their own equipment slot in the player's inventory.

Buffs
The following Buffs provide light as a result of a Potion or Magic item.

Incidental light sources
The following items produce varying amounts of light, even though lighting is not their primary function.

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.

Growable
These can be spawned given the right conditions, which occur naturally and can also be induced by the player.

On world generation only
These are produced only on World creation, and can not be picked up, used, or placed by players.
