Copper Bulb
minecraft:copper_bulbA copper bulb is a redstone light source crafted from a block of copper, a blaze rod, and redstone dust, yielding four bulbs. It toggles on or off with a redstone pulse and stays lit without needing continuous power, with brightness decreasing as it oxidizes.
FAQ
How do you craft a copper bulb?
Combine a block of copper, a blaze rod, and redstone dust to craft four copper bulbs.
How does a copper bulb turn on and off?
It toggles its lit state whenever it receives a redstone pulse and does not require continuous power to stay lit, making it useful for T flip-flop circuits.
Does oxidation affect a copper bulb's light output?
Yes, light level drops from 15 at normal copper down to 12, 8, and 4 as it progresses through exposed, weathered, and oxidized stages.
Where can you find copper bulbs naturally?
Copper bulbs generate naturally within trial chambers, which were introduced in the Tricky Trials update.
