Jack o'Lantern

Jack-O-Lanterns are a new feature implemented by Notch in the Halloween Update of October 31st 2010. They are intended as a purely decorative addition although they can also be used as a light source. Their luminance is somewhat greater than that of the torch. They appear identical to unlit pumpkins in the inventory.

A Jack-O-Lantern is created by combining a pumpkin and a torch (See Crafting below). A video guide on how to create a Jack-O-Lantern is below as well.

Jack-O-Lanterns produce the same amount of light and share same the ability to stay lit underwater as Lightstone, making them a more effective, safer, and more easily obtained method of lighting than either fire or lightstone.

Jack-O-Lanterns and pumpkins are 2 of the many blocks that are broken more quickly with a sword, but still have double damage on the sword.

Trivia

 * The Jack-O-lantern, unlike the torch, can be placed underwater and can still stay lit, making it one of the best sources of light for water.
 * In SMP, if a Jack-O-Lantern is placed on leaves, the block will be placed but it will not be removed from your inventory, effectively duplicating the block.
 * As with the pumpkin, a Jack-O-Lantern can only be placed if there is another block below it. However, it will remain in place if you remove the block below it after placing it.
 * The Jack-O-Lantern is also an infinite source of light. This may be an alternative to the Lantern once a future update makes torches finite.
