A broken lamp in Dorgesh-Kaan.A map of all possible broken lamp locations that require a new Light orb to grant experience.
Light orbs can be used to fix magical lamps in Dorgesh-Kaan. Level 52 Crafting and Firemaking is needed to fix a lamp, giving 500 Crafting experience and 500 Firemaking experience. When a player has replaced 50 light orbs they will receive the message "You have replaced 50 orbs and have gained extra experience." The bonus received is 2,500 Crafting and Firemaking experience. This can be repeated indefinitely.
Broken lamps are found on all three floors. The large street lamps throughout Dorgesh-Kaan never need replacing. Broken lamps can be hard to distinguish from a distance. There are always ten broken lamps, and once one is fixed, a new one will break. Broken lamps are unique to each player and are the same for the player no matter what world the player is on.
In addition to attaching cave goblin wire to empty light orbs via the Crafting skill (requires 87 Crafting, granting 104 experience), complete light orbs are sometimes obtained from Dorgesh-Kaan Average Chests, specifically from the chest on the 2nd floor in Oldak's house. Empty orbs are obtained by looting a chest only slightly more frequently than completed light orbs.
Fixing the lamps throughout Dorgesh-Kaan gives roughly 130,000 Crafting experience and 100,000 Firemaking experience per hour. However, reaching this rate will require being familiar with the locations of the lamps throughout Dorgesh-Kaan and the fastest ways to reach them. While still learning, players should expect as low as 90,000 Crafting experience per hour. Additionally, if players have not completed the Elite Lumbridge & Draynor Diary, their experience rates will be reduced because it will take twice as long to thieve the wire.
To start, players should take an inventory of empty light orbs to the wire machine. Either craft the empty light orbs ahead of time or take an inventory of molten glass and craft it while running to the wire machine. Once there, fill all of the light orbs with cave wire. Then, either work clockwise or counterclockwise around the city fixing lamps. After fixing a lamp at the bank, grab more items from the bank and start again. Every time the player fixes a lamp, the game will indicate where a nearby broken lamp is. Because only one lamp location is given, players should also keep an eye out for other nearby lamps that can also be repaired and prioritise lamps in an order that requires the least amount of backtracking. Whenever there are no nearby lamps, using a Dorgesh-kaan sphere to teleport to a random location in the city can help to reach another broken lamp quickly.
Note: which exact lamps require fixing at any given time are tracked per player, not per world, so world-hopping does not work to try to find closer lamps to fix. The RuneLite plugin "Dorgesh-Kaan lamps" will point the player to the closest lamps to fix and is recommended.
