A large XP lamp is a purchased reward from the Battle of Lumbridge, which grants the player 95% of the experience a large prismatic lamp would give. The experience gained is the same from level 98 to 120. After the week 9 vote, the store price was reduced to 1235 renown. Note: If you use a large XP lamp on Dungeoneering, you will not be awarded with the dungeoneering tokens.
