A candle is the lowest level lightsource. When a tinderbox is used on a candle it will become a lit candle. Lit candles can be extinguished by clicking on them or by falling into swamp water inside the Lumbridge Caves.

An (unlit) candle is a requirement for Enlightened Journey and Enakhra's Lament.

Candles can be bought from the Candle Shop in Catherby for three to four gold pieces each. A lit candle will also spawn in the Ardougne Monastery, in the Watchtower north of Yanille, and on the 1st floor[?] of the sword shop in Varrock. You can also buy a lit candle from the candle seller outside of the Lumbridge Swamp Caves entrance for 1000 gold. It can also be stolen from the church on Entrana.
