The copper bulb is a redstone-powered light source that toggles between lit and unlit when it receives a pulse, rather than needing continuous power like a redstone lamp.

Uses

  • Redstone Toggle Light — A single redstone pulse flips it between lit and unlit and it holds that state, making it useful for flicker-free lighting circuits and puzzle mechanisms.
  • Comparator Signal — A comparator reads a lit copper bulb as signal strength 15 regardless of its oxidation stage.

Found In

  • Trial Chambers — Naturally generates lit, waxed at various oxidation stages throughout trial chamber structures.
  • Crafted — Made from 1 block of copper, 1 blaze rod, and 1 redstone dust, yielding 4 bulbs.

FAQ

What tool do I need to mine a Copper Bulb?

A stone pickaxe or better; anything weaker breaks it with no drop.

Does oxidation change how bright a Copper Bulb is?

Yes. Light output drops from 15 (normal) to 12 (exposed), 8 (weathered), and 4 (oxidized).

Does a Copper Bulb need constant redstone power to stay lit?

No. It only needs a momentary pulse to toggle state, then stays lit or unlit until pulsed again.

Can I stop a Copper Bulb from oxidizing?

Yes, apply honeycomb to wax it, locking its current oxidation stage and light level in place.
