Lantern

Lanterns are blocks that emit light.

Usage
Lanterns can be placed on the top or hanging under most solid blocks, although some will require (see placement for exceptions).

Light
Lanterns give off a light level of 15, which is slightly more than torches.

History
Lanterns were crafted blocks originally planned to be added in the Halloween Update. However, they were delayed due to lack of time and were going to be implemented in a future update. With the addition of the lantern, torches would flicker out and need to be re-lit with flint and steel. The lantern would serve as a permanent source of light. According to Notch, when the update would occur, all torches placed on the map, in the inventory, and in chests (tile entities) prior to the update would be converted to lanterns. To do this, the lanterns would use the (former) block ID of torches along with a re-skin. On January 13, 2011, Notch claimed that lanterns were "postponed", and added on January 20 that he was "not sure" when they would be implemented. Notch announced on November 18, 2011, at the Mojang Panel at MineCon 2011, that lanterns would not be added to Minecraft due to large negative community response towards the effects the new item would have had on torches. Instead, other types of lighting would be added, such as redstone lamps and glowstone. Sea lanterns were added in 1.8 snapshot 14w25a, with the addition of ocean monuments. However, these sea lanterns did not make any change to how torches function; they can still be lit up for infinity. On November 9, 2018, LadyAgnes tweeted an image of a lantern, implying that they are once again in development.
