Usage

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; it blocks sky light, mobs suffocate in it, and it conducts redstone power. It also allows mobs to spawn on them while it is unlit.

Lit redstone lamp "item"

The following content is transcluded from Technical blocks/Lit Redstone Lamp.

Java Edition
1.2.1		12w07a			Lit redstone lamps have an item form corresponding to its block ID. It can be obtained via inventory editors with numeric item ID 124.
					Interestingly, unlike most items of this type, lit redstone lamps are themselves dropped by lit redstone lamps.
					Pick Block on a lit redstone lamp block would highlight any existing lit redstone lamp blocks in the hotbar, rather than normal redstone lamps.
1.2.4		release			Lit redstone lamps now drop normal redstone lamp items when broken in most cases. They can still be obtained by breaking one with a Silk Touch enchanted tool.
1.2.5		pre			Pick Block on a lit redstone lamp now always returns a normal, unpowered redstone lamp.
1.3.1		12w16a			Lit redstone lamp items can now be obtained in singleplayer worlds via the /give command using the respective numeric ID.
1.7.2		13w37a			The direct item form of lit redstone lamps has been removed from the game. It can no longer exist as an item in any way, only as a placed block.
					The ability for lit redstone lamps to drop lit redstone lamp items via Silk Touch has not been removed, however. As a result, attempting to obtain a lit redstone lamp this way in this version crashes the game with a NullPointerException.
		13w38a			Lit redstone lamp blocks now drop unlit items regardless of tool.
?					Added BlockStateTag, which allows to obtain all valid block states of respective block. This tag allows to obtain many technical blocks otherwise cannot be obtained, including lit redstone lamp.
Bedrock Edition
?					Lit redstone lamps probably exist as an item.

Appearances

Java Edition
1.2.1		12w07a			The lit redstone lamp item uses this model in inventories, when held in first or third person view or as a dropped item.
		1.2			The lit redstone lamp item uses this model in inventories, when held in first or third person view or as a dropped item.
					This is due to the redstone lamp texture changing in this version.
1.3.1		12w22a			The lit redstone lamp item now uses this model in inventories, when held in first or third person view or as a dropped item.
					This is a result of all 3D items being rotated 90 degrees anticlockwise from their prior appearances.
1.4.2		12w34a			The lit redstone lamp item now uses this model in inventories, when held in first or third person view, as a dropped item or when in an item frame.
					This is a result of all 3D items being brightened to a miniscule degree.

  Demonstrating how a solid block powers redstone lamps.

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

  A way you can use lit redstone lamps in building.

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.
