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]
November 11, 2010 | Notch claimed that "lamps" had actually stood for "Light A-givin' Material Portal Side... the yellow stone thing". | ||||
---|---|---|---|---|---|
Java Edition | |||||
1.2.1 | 12w07a | ![]() ![]() | |||
1.2 | ![]() ![]() | ||||
1.2.4 | release | A 2-tick delay to deactivation has been added to redstone lamps. | |||
Lit redstone lamps now drop unlit redstone lamps when broken. | |||||
1.7.2 | 13w37a | The 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. | |||||
13w38a | Lit redstone lamps now drop regular redstone lamps, which has fixed the crash from 13w37a. | ||||

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.
