Minecraft:Copper Bulb

Template:Infobox block A copper bulb is a light-emitting Minecraft:block. It toggles on or off when it receives a Minecraft:redstone pulse, and does not need continuous power to emit light. Its light level depends on its state of oxidation.

Waxed copper bulbs do not oxidize, but otherwise function identically.

Obtaining

Breaking

Copper bulbs can be mined only with a stone pickaxe or better. If a copper bulb is mined without the use of a valid pickaxe, it drops nothing. Template:Breaking row

Natural generation

Lit, waxed copper bulbs in random states of oxidation are generated in trial chambers.

Usage

Copper bulbs can be activated to emit light, with the light level emitted decreasing for each stage of oxidation. When the copper bulb receives a redstone pulse, it instantly toggles between its lit and unlit states.

Redstone component

A comparator can read the state of a copper bulb, and it emits a signal strength of 15 if the bulb is lit, regardless of oxidation. If the bulb is unlit, the comparator does not emit any power, allowing this comparator and copper bulb combination to act as a compact T flip-flop.

While the copper bulb is receiving redstone power (either to toggle the bulb on or off) a red dot appears in the center of the block. An Minecraft:observer can detect this, and emits a signal when a copper bulb becomes powered or unpowered.

in Template:Editions, the copper bulb can only activate on the input/consumer redstone tick (C-tick).

Oxidation

{{#vardefine:params|0 }}Template:Hatnote Non-waxed copper bulbs have four stages of oxidation (including the initial normal state). Lightning bolts and Minecraft:axes can remove the oxidation on copper bulbs. They can be waxed with Minecraft:honeycomb to prevent oxidation from progressing.

As the block begins to oxidize (exposed), it gets discolored and green spots begin to appear. As the oxidation continues (weathered), the block is a green color with brown spots. In the last stage (oxidized), the block is teal with several green spots.

The light level emitted by copper bulbs also changes depending on the stage of oxidation.

Oxidation level	Light level
redirect Template:BlockSprite Template:Redr Normal	15
redirect Template:BlockSprite Template:Redr Exposed	12
redirect Template:BlockSprite Template:Redr Weathered	8
redirect Template:BlockSprite Template:Redr Oxidized	4

Sulfur cube

Template:Message box Template:Article other Sulfur cubes have the ability to absorb copper bulbs at any stage of oxidization, either through picking them up or being interacted with them. This provides the medicine ball/slow flat effect to the mob when hitting it.
