Making and Using a Copper Bulb in Minecraft 1.21

The Minecraft 23W43A snapshot heralds the arrival of the long-awaited copper block update, now in full swing. Among the new additions is the remarkable copper bulb, an unprecedented light source block with unique properties. In this guide, we delve into all things related to the copper bulb in Minecraft 1.21.

The copper bulb functions both as a light source and possesses redstone capabilities, allowing for activation and deactivation through redstone power. Here, we outline the process of crafting a copper bulb, its functionality, and practical usage.

Defining the Copper Bulb

Copper bulb functions like other copper blocks, progressing through four oxidation stages and can be waxed with honeycomb or scraped with an axe, emitting light based on its oxidation stage.

Materials for Crafting Copper Bulbs

The crafting recipe for copper bulbs demands several resources, requiring some effort and preparation. Fortunately, the recipe yields a minimum of four bulbs per craft. To create copper bulbs, gather:

  • 3 Copper Blocks
  • 1 Blaze Rod
  • 1 Redstone Dust
  • 1 Crafting Table or Crafter

Copper blocks crafted using nine copper ingots. Blaze rods drop from blaze mobs in Minecraft, ranged and melee mobs found only in the Nether fortress. Since they shoot fireballs, bring fire resistance potions in this dimension.

Redstone dust, a precious material dropped while mining redstone ores. The crafting table, a utility block for complex crafting actions, crafted easily with 4 wooden planks. Alternatively, use the new auto-crafter in Minecraft 1.21, similar to the crafting table, but supporting crafting triggered by a redstone signal.

Minecraft 1.21 Copper Bulb Crafting Recipe

  • Place the crafting table or the crafter in your world.
  • Right-click the block to access its crafting grid. Start by placing the blaze rod in the center slot of the 3 x 3 grid.
  • Then, place redstone dust beneath the blaze rod in the bottom row.
  • Finally, surround the blaze rod with copper blocks in the three empty cardinal direction slots.
  • If you’re using the crafting table, select the copper bulb on the right and add it to your inventory.

However, when using the new crafter block, ensure it’s powered once to dispense the items. This can be done with a lever, button, or any other redstone power source.

Where to Find Copper Bulbs in Minecraft

Fancy lamps are costly to produce, but there’s a more economical alternative. Fortunately, copper bulbs abound in the trial chambers of Minecraft 1.21. These chambers, varying in size, reside beneath the deepslate layers of the Overworld dimension. However, they aren’t found as deep as ancient cities.

Copper bulbs are integrated into the walls, illuminating their surroundings. They’re commonly dispersed across all chamber levels, ensuring a substantial yield even from smaller chambers.

Functionality of Copper Bulbs in Minecraft

Using a copper bulb differs from a regular redstone lamp. The main feature is that this block turns on and off with each power input. If powered with a lever after placement, it turns on. When the lever is deactivated, the bulb remains on. Activating the lever again turns the bulb off.

Additionally, when receiving constant power, the bulb displays a red dot at its center, regardless of its on/off state. These states are easily detectable by an observer.

  • No oxidation (fully orange) – light level 15
  • Exposed version (mostly orange with green spots) – light level 12
  • Weathered copper bulb (mostly green with orange spots) – light level 8
  • Oxidized copper bulb (fully green) – light level 4.

You can wax these bulbs in any state using a honeycomb, and they will retain that state until scraped off with an axe.

Copper bulbs are also a redstone power source. Placing a redstone comparator to read the signal of the bulb will light up if the bulb is on. The signal remains 15, regardless of oxidation.

If the bulb is off, it will not send the signal, applicable to both powered states displaying the “red dot” in the center.

How to Use a Copper Bulb in Minecraft 1.21

With the properties mentioned above, follow these steps to use a copper bulb in the game.

After crafting a copper bulb, place it in the world. Then, power it using any redstone source: lever, button, or redstone block. Attach the lever or button on top and activate by right-clicking. If using a redstone block, attach it directly to the bulb. Activating the copper bulb will turn it on and emit light.

When the power source is deactivated, the copper bulb remains on, as explained earlier. This mechanic is important as a redstone feature and may appear in various farms and other redstone contraptions.

Break the power source and place the copper bulb anywhere. Optionally, keep it waxed for a steady light. Otherwise, it will gradually oxidize, dimming the light. Alternatively, connect it to a comparator or observer to monitor its state.

To switch off the copper bulb, apply a redstone signal again.

The possibilities with the copper bulb are vast. It greatly enhances lighting customization, proving invaluable in various situations. We eagerly anticipate the community’s innovative uses of this remarkable block. What are your thoughts? Share them with us and fellow readers below!
