Light sources are used by players via the Firemaking skill to illuminate dark caves and dungeons. Without a light source, some dungeons are pitch black with zero visibility. Some dungeons prohibit access without a light source and attempting to extinguish a light sources is not allowed.
Any tier of kandarin headgear is highly recommended light source, as it only requires the easy Kandarin Diary and is not extinguishable. A bullseye lantern is a viable alternative, though it can be extinguished by certain monsters or dungeons.
Light sources can be extinguished by the player, by NPCs, and by the environment.

Locations that are dim[edit | edit source]
This is a list of locations that are dimmer than usual, but a light source is not required:
Consequences of no light[edit | edit source]
If stuck without a light source, logging out resets the timer before taking damage.
After 9 seconds (15 ticks) of not having a light source, it triggers the following message: You hear tiny insects skittering over the ground...
After another 9 seconds (15 ticks) without a light source another message appears: Tiny biting insects swarm all over you! and the player will begin to take damage in quick succession of 1 Hitpoints until they escape the darkness, reignite their light source, or die.
Nothing can protect from this damage, however certain emotes, such as a Skill Cape emote, though unable to block the attacks, can temporarily stall the damage. Once out of the movement phase of the emotes, you will get hit for the damage missed while in the movement.
Players cannot attack without a light source in dark areas.
Gas explosion[edit | edit source]
Torches, candles, and oil lamps cause explosions in certain areas of the Lumbridge Swamp Caves. A message displays in the chat box, "Your [light source] flares brightly!" and then "The swamp gas explodes" unless the player leaves the area quickly enough or has an alternate light source that isn't going to explode and extiguishes any in danger of doing so.
The explosion extinguishes the light source and causes damage equal to 25% of the player's total Hitpoints. The central southern area of the cave, on the way to the Chasm of Tears, can be traversed safely without explosion, though there are better routes and the player is in danger of wall beasts. Stop one tile before them then run across to avoid being grabbed.
Water[edit | edit source]
Falling into the water of Lumbridge Swamp Caves by failing the stepping stones or choosing the wrong path in the Dorgesh-Kaan mine extinguishes candle lanterns, oil lanterns, torches, candles, and oil lamps, but not mining helmets or bullseye lanterns.
Extinguished[edit | edit source]
While players can manually extinguish many light sources, there are also monsters and environment that can do so to:
- Scarab mage: Ocassionally make every extinguishable light source go out with the following message: Your lights have been magically extinguished.
- Giant mole: When digging away will sometimes extinguish any candles, torches, or oil lamps
- Scarab trap: In Sophanem Dungeon, falling into this trap extinguishes every possible light source.
- Explosions: Only affects candles, torches, and oil lamps
Types of light source[edit | edit source]
There are three equippable light sources: bruma torch, Kandarin headgear, and the Firemaking cape. Those cannot be extinguished, nor can the Fire of Eternal Light built in the Falador Mole Lair, Lumbridge Swamp Caves, and Mos Le'Harmless Cave.
Every other light source must be lit by the player, requiring a certain Firemaking level, and is extinguishable by the player or other means. All of them can be lit by a tinderbox, but a torch can also be lit by rubbing together dry sticks.
There are three levels of brightness, 1 being the lowest and 3 the highest, brightness from these items will stack up to 3. For example, the brightness of three candles is equivalent to the brightness of one bullseye lantern.
|Torch||1||1||Instant||Can be lit in the water-filled chamber of the Haunted Mine by using dry sticks on the unlit torch|
|Black candle||1||1||4.2 seconds
|Obtainable only during the Merlin's Crystal quest|
|White candle lantern||4||1||No|
|Black candle lantern||4||1||No|
|Oil lamp||12||2||4.2 seconds

Adding oil[edit | edit source]
Oil lamps, oil lanterns, and all three bullseye lanterns needs to be filled with oil before they can be lit. To add oil, swamp tar must be distilled at either the lamp oil still in the Chemist's house in Rimmington or the lamp still next to Miltog in Dorgesh-Kaan.
Trivia[edit | edit source]
- The bug lantern is not a light source despite its name. Its only use is for Slayer to kill Harpie Bug Swarms.
- Combining multiple light sources increases the brightness, however a brightness level above 3 makes no difference.
- Dungeons that require a light source are the only locations where its possible to adjust the lighting without changing graphics options, a possible use for videomaking.
- The city of Dorgesh-Kaan is kept alight by hundreds of magical lamps. Their lamps often break, which the player can repair with a light orbs for Firemaking experience, but the brightness level never goes down.
