Name:Redstone Lamp
Type:Block

Renewable:No
Item ID:redstone_lamp

A redstone lamp is a block which gives off light when powered by redstone.

Obtaining

A redstone lamp can be mined by hand or with any tool, dropping itself as an item.

Crafting

Four pieces of redstone dust and one piece of glowstone dust are required to craft a redstone lamp.

Empty Redstone dust Empty
Redstone dust Glowstone Redstone dust

Redstone lamp

Usage

A powered redstone lamp produces a light. An inactive redstone lamp produces no light. It can be activated instantly, but it takes 2 redstone ticks to turn off (4 game ticks, or 0.2 seconds barring lag). 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)

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.

Light bulb

The redstone lamp used to be the light bulb. It functioned in exactly the same way, and the only difference was the name and the texture, so it did not have any extra physics. It was then changed to the redstone lamp in 1.24. This was how the lightbulb was crafted:

Empty Glass Empty
Glass Redstone dust Glass
Empty Iron ingot Empty
Light bulb
