A redstone lamp is a block which produces light when activated with a redstone trigger.
A redstone lamp can be mined by hand or with any tool, dropping itself as an item.
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 above or below: for example, a redstone torch (except that a redstone torch will not activate a redstone lamp it is attached to)
- An adjacent powered block, including above or below
- Adjacent powered redstone dust (or on top of 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.
Although a redstone lamp acts like an opaque block in most ways (torches and levers can be attached to it, redstone dust can be placed on it, etc.).
