Usage[edit]

A redstone lamp can be used to produce switchable light.

Redstone lamps are redstone mechanisms and can be activated by:

  • An adjacent active power component, including above or below: for example, a redstone torch (except that a redstone torch does not activate a redstone lamp it is attached to), a block of redstone, a daylight sensor, etc.
  • An adjacent powered block (for example, an opaque block with an active redstone torch under it), including above or below
  • A powered redstone comparator or redstone repeater facing the redstone lamp
  • Adjacent powered redstone dust configured to point at the redstone lamp (or on top of it) or directionless; a redstone lamp is not activated by adjacent powered redstone dust that is configured to point away from it.

A redstone lamp activates instantly, but takes 2 redstone ticks to turn off (4 game ticks, or 0.2 seconds barring lag).

An active redstone lamp produces block light 15. An inactive redstone lamp produces no light.

A redstone lamp acts like an opaque block; torches and levers can be attached to it, it blocks sky light, mobs suffocate in it, and it conducts redstone power.

History[edit]

Java Edition Alpha
November 11, 2010Notch claimed that "lamps" had actually stood for "Light A-givin' Material Portal Side... the yellow stone thing".
Java Edition
1.2.112w07aRedstone Lamp JE1.png Lit Redstone Lamp JE1.png Added redstone lamps.
1.2Redstone Lamp JE2 BE1.png Lit Redstone Lamp JE2 BE1.png The texture of redstone lamps has now been darkened, and the texture of lit redstone lamps has been slightly changed.
1.2.4releaseA 2-tick delay to deactivation has been added to redstone lamps.
Lit redstone lamps now drop unlit redstone lamps when broken.
1.7.213w37aThe item form of block ID 124 (lit redstone lamp) has now been removed from the game. It can no longer exist in inventories, only as a block in the world. This means it can no longer be obtained by Silk Touch either.
Since the drop for lit redstone lamps has not been removed, mining a lit lamp with Silk Touch still triggers the game to drop a lit lamp, but because such an item no longer exists, the game now crashes with a Null Pointer Exception error.
13w38aLit redstone lamps now drop regular redstone lamps, which has fixed the crash from 13w37a.
January 11, 2018Redstone Lamp JE3 BE2.png Lit Redstone Lamp JE3 BE2.png Jasper Boerstra tweets an image of updated redstone lamp textures.
1.1317w47aThe different block IDs for the redstone lamp has now been merged into one ID.
A lit block state has been added to redstone lamps.
Prior to The Flattening, these blocks' numeral IDs were 123 and 124.

Issues[edit]

Issues relating to "Redstone Lamp" are maintained on the bug tracker. Report issues there.

Trivia[edit]

  • Multiple tiled redstone lamps produce a pattern that resembles the truncated square tiling t{4,4}.
  • Redstone lamps are transparent on maps.

Gallery[edit]

Since lamps themselves are solid blocks, they power other lamps. This causes the cross-shaped patterns of lit lamps.

A glowing roof can be done by laying wire across the blocks, or lining the top of the lamps with redstone blocks. Floors and walls are also do-able. A glowing floor can be created by using "knight's move" shape underneath the floor with torches. A glowing wall uses wall-mounted torches that power blocks above them.
