Behaviour

Power

A redstone torch is lit unless the block it is attached to is powered. It switches 2 ticks after that block's power changes. A random tick can switch it sooner. A torch on a fence stays lit, as a fence is never powered.

A lit redstone torch powers every block beside it except the one it is attached to, and strongly powers the block above it.

Burning out

A redstone torch that turns off for the 8th time within 100 ticks burns out, with a hiss and a puff of smoke. It stays off while 8 of its turn-offs lie within the last 100 ticks, and relights at its next block update or random tick after that.

Every torch in the running game records its turn-offs in one list, shared by every world and dimension loaded since the game started. A torch counts the turn-offs recorded at its coordinates, whichever world made them.

Turn-offs are cleared from the oldest end of the list, against the clock of the world the clearing torch is in. A turn-off dated later than a world's clock cannot be cleared by that world's torches, and holds back every turn-off recorded after it. While it stays, a torch in that world burns out at its 8th turn-off in all, and does not relight. This happens:

• in a singleplayer world opened after one with a later time, without restarting the game;
• in a server's Nether once players sleep through a night, which moves the Overworld's clock on and not the Nether's. Each Overworld torch that turns off then holds back the Nether's turn-offs until a torch in the Overworld updates more than 100 ticks later;
• on a server, after time set to an earlier time.
