Light orb

Light orbs can be used to fix magical lamps in Dorgesh-Kaan, by using an empty light orb on a piece of Cave goblin wire. Level 87 Crafting is needed to create a light orb, which gives 104 Crafting experience, and level 52 Firemaking is needed to fix a lamp, giving 1000 Firemaking experience. When a player has replace 100 light orbs they will receive the message "You have replaced 100 orbs and have gained extra experience." The bonus received is 5000 firemaking xp.

Orbs only fail on the lamps found inside rooms. The large street lamps throughout Dorgesh-Kann never need replacing. Because of this it is rare to encounter a broken lamp. However, if repairing lamps is combined with thieving training on Dorgesh-Kaan average and rich chests then one may encounter up to seven (7) broken lamps on a single complete circuit; if one visits every room, including those without chests.

In addition to making light orbs via the crafting skill, complete light orbs are rarely obtained from the Dorgesh-Kaan chests. Empty light orbs are obtained by looting a chest only slightly more frequently than completed light orbs. However, given the player has sufficient levels in crafting and thieving, training thieving and firemaking together in Dorgesh-Kaan is reasonably efficient.

Despite the large amount of firemaking experience given, finding the broken lamps can be frustrating. It may be useful to make fires in the city and take quick glances at nearby lamps in hope of a broken lamp being found, though don't go asking people if they have seen any because they are different for each person.

A ring of fire and flame gloves can increase your experience for lighting the lamps to 1050 per lamp.

At level 78 Thieving, it is a potential loot from the Dorgesh-Kaan - Rich Chest.
