Exposed Copper Bulb is the first oxidation stage of the Copper Bulb, a light source that toggles on and off when it receives a redstone pulse rather than needing continuous power. Its light output drops to level 12 at this stage.

Uses

  • Waxed Exposed Copper Bulb — Apply Honeycomb to halt oxidation at this stage, locking its light level and toggle behavior in place.

Found In

  • Trial Chambers — Generates lit, wired to redstone, as part of Trial Chamber vault and mechanism decoration.
  • Natural weathering — Forms over time when an unwaxed Copper Bulb progresses from its unoxidized state.

FAQ

What tool do I need to mine Exposed Copper Bulb?

A stone pickaxe or better. Mining with a wooden pickaxe or by hand drops nothing.

How does it toggle on and off?

A redstone pulse flips its lit state; unlike a redstone lamp, it does not need continuous power to stay lit, making it useful for compact toggle circuits.

Does oxidation affect its light level?

Yes. Light output falls from 15 (unoxidized) to 12 (exposed) to 8 (weathered) to 4 (oxidized).

How do I stop it from oxidizing further?

Apply Honeycomb to wax the block, which locks it at the Exposed stage and preserves its current light level.
