A '''redstone lamp''' is a solid [[block]] that produces [[light]] while it is receiving [[redstone]] power.

== Obtaining ==
=== Breaking ===
A redstone lamp can be mined with any [[tool]]<ref>{{bug|MC-192719||Sea Lantern, Glowstone, Redstone Lamp don't have an assigned tool}}</ref> or by hand, dropping itself as an [[item (entity)|item]].
{{breaking row|horizontal=1|Redstone Lamp}}

=== Natural generation ===
Redstone lamps generate naturally in [[ancient cities]].

== Usage ==
A redstone lamp can be used to produce switchable [[light]]. 

Redstone lamps are [[Redstone components#Mechanism components|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 [[tick]]s, or 0.2 seconds barring lag) in [[Java Edition]] or 3 redstone ticks to turn off (6 game [[tick]]s, or 0.3 seconds barring lag) in [[Bedrock Edition]].

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, [[mob]]s suffocate in it, and it conducts redstone power. It also allows mobs to spawn on them while it is unlit.
