This talk page is for discussing the Huge XP lamp page.

Formula[edit source]

The formula Xp = 767.112612 - 14.86190469x + 6.836504517x² - 0.1395473222x³ + 0.0014656899x^4 [where x=level] is a more accurate quartic function than the one provided. Still, neither of them are correct, and I have reason to believe that the chart provides incorrect information too - the xp gained at level 28 (3312) is said to be less than the xp gained at 27 (3331).

Xp rates[edit source]

So then, does anyone know what sort of xp rates these give? Are they dependant on level? Or is it just a single amount of xp? Lemon2020 19:50, February 28, 2012 (UTC)

Data is being gathered to try and find a formula, over on Talk:Squeal of FortuneSmall recharge gem.png AnselaJonla Slayer-icon.png 21:34, February 28, 2012 (UTC)


there is mention of assorted lamp values per lv and it appears that the lamps that can be used freely give less xp than the ones that have to be used on a specific skill

Where did the data on the page come from? Because there is an inconsistency in the values at level 44 (xp value is 7120) and 45 (xp value is 7116, lower then for 44) I'm inclined not to trust this data.

   The data for level 44 for was incorrect on both the Huge and Large lamp pages. I have just fixed the numbers.   I do not know the exact formula for experience, but a medium lamp gives twice the xp of a small lamp, a large gives twice that of a medium, and a huge gives twice that of a large.

Experience Gained Formula[edit source]

The formula displayed here is wrong. I agree it is close but it does not match any of the data available (on a side note I do no think that the data that is available is correct). Furthermore it is not an exponential formula, it is a polynomial.


Yeah, I agree. The polynomial given does seem to be off (where x=66, the value given using the polynomial is 19,744.8, almost 2.5k off). Also, it just could be me that thinks this, but I think it is unlikely that Jagex would use a polynomial that precise. Lemon2020 21:55, April 21, 2012 (UTC)


The actual formula will be similar to the experience needed for a level, it will not be a polynomial. 82.20.32.138 23:54, June 17, 2012 (UTC)

Double Experience from a Huge Lamp from Mad Necklace?[edit source]

Just received a Huge XP Lamp (Prayer) from Meg in PoP, and it's experience was doubled by the Mad Necklace. I read further on the Mad Necklace page that it didn't stack with XP Lamps, but it doubled the xp received any way. Is this intented or is it a bug?

TH promo[edit source]

It seems the current TH promo (which boosts experience received in certain skills such as Prayer from lamps) also works on non-TH lamps (likely they're just the same item). I received 86,019 Prayer experience from my weekly Dimension of Disaster Huge XP lamp just now, as opposed to the normal 68,815. IP83.101.44.209 (talk) 05:31, June 14, 2015 (UTC)
