Examine	Squeal: This lamp has an air of awesome power about it. Meg: A huge lamp that smells of the sea.

A huge XP lamp is a very rare prize rewarded from the Squeal of Fortune, Meg in Player-Owned Ports, or trading with renown at the quartermaster in your god's camp, which grants the player a definite amount of experience scaled to the selected skill level. It grants twice the experience of a large one, four times the experience of a medium, or eight times the experience of a small one. As with most lamps, this item may not be stored in a bank. The experience gained stays constant from level 99 to 120.

If the player receives one of these lamps, it is highly recommended to utilise it on a skill that is either expensive, such as Prayer, Herblore, Construction, or time-consuming, such as Slayer, Summoning, and Agility.

As of an update on 12 October 2012, skill-specific huge lamps in Construction, Crafting, Farming, Herblore, Smithing and Summoning have been replaced by crates containing training items for the skills.

Note: If using a huge XP lamp on Dungeoneering, dungeoneering tokens will not be received.

Formula

Below is a polynomial formula which loosely approximates the experience gained in a skill at level L. $XP=0.00114633L^{4}-0.0834637L^{3}+3.64364L^{2}+49.7911L+459.517$

One can also use an exponential formula to approximate experience gained at level L: $XP=848.27e^{0.0458L}$

Trivia

• Unlike other very rare rewards, winning a huge XP lamp on the Squeal of Fortune does not produce an event on one's adventure log.
