Waxed Copper Bulb

In Minecraft, the waxed copper bulb is a unique light-emitting block introduced in the 1.21 Tricky Trials update. Unlike regular copper bulbs, waxed copper bulbs do not oxidize and turn green over time. They are crafted by placing three waxed copper blocks, one blaze rod, and one redstone dust in a specific pattern in a crafting table, yielding four bulbs per craft. The light level of a waxed copper bulb depends on its oxidation stage: 15 when unoxidized, 12 when exposed, 8 when weathered, and 4 when oxidized. Importantly, waxed copper bulbs toggle on and off with a single redstone pulse and do not need constant power. They also act as a redstone power source, sending a signal to comparators. Players can find waxed copper bulbs within trial chambers. Their versatility makes them suitable for decorative purposes and redstone contraptions. Their unique attributes, such as the oxidation state changes and the on/off toggle with a single redstone pulse, make them a valuable and creative addition to the game.
