레드스톤 횃불은 광원의 역할을 하지만 실용적이지는 않다. 석탄을 이용한 횃불의 절반인 bl 7 정도로 눈이나 얼음을 녹일 수 없고, 몹의 스폰을 막을 수 없다.
그러나 약간의 빛도 시야 확보에 도움이 되기 때문에, 비효율성을 역이용하면 몹 스폰에 영향을 주지 않으면서 시야를 확보할 수 있다.
A Redstone Torch can provide a power source for wires. Wires in turn are used to operate doors, pistons or switches from a distance. The torch can power the wire for a length of 15 blocks, and takes 1 tick in Minecraft world time (approximately 0.1 seconds) for power to flow through it.
If Redstone is scarce, and the only purpose of the torch is to supply power (i.e. not being used in any logic gate), it can usually be replaced with a lever, with the added advantage of being turned off if the need arises.
The Redstone Torch will constantly power a set of wires while placed, and is used as a "block-based" switch sometimes. It acts as an inverter, or NOT-gate (and is labeled as such in the game's source code), in Redstone circuits, and turns off when any adjacent switch, lever, wire or pressure plate is turned on. See Redstone circuits for more information on using Redstone torches in circuits and logic gates.
Redstone torches can be used to sabotage/activate traps and mechanisms as well as opening locked iron doors making it useful for raiding parties in multiplayer. A door circuit designed to be closed when constantly powered prevents this vulnerability.
Redstone torches will burn out when switched between the on and off states too often (8 or more off-on-cycles within 100 ticks or approximately 5 seconds). This typically happens when the player creates an infinite feedback loop by inadvertently or purposely wiring a redstone torch back into itself (a one clock). This will cause the torch to apply a current to itself thus turning it off and removing current allowing the torch to come back on and once again apply current to itself. This will cause the torch and any mechanisms wired to it to rapidly activate and deactivate repeatedly and could crash the game depending on the complexity of the mechanism. This is likely why Notch programmed the torches to burn out. When burnt out the torch will issue a puff of smoke and a hiss similar to an extinguished torch. Then it will ignore any events which would normally turn on the torch until enough time has been elapsed so that there are 7 or less off-on-cycles within the last 100 world ticks. After that a new event of unpowering the blocks adjacent to the torch is necessary to turn it on again (current state of the blocks is ignored, it requires a new on-off-edge or a general kind of block update). There is no limit how often a single redstone torch can burn out.
Redstone torches can also burn out if one clicks a lever quickly and repeatedly with the lever being hooked up to a redstone torch or leads a wire from the torch, up one block, and reconnects it to the torch.
- It seems that since the 1.7_01 update in SMP, once a redstone torch has cycled an arbitrary number of times in too short a period (about 5 minutes), it becomes "stuck" in the "off" state until either the weather changes or the time changes (naturally) between day/night, presumably to limit network traffic and prevent abuse. This is separate from "burning out," which happens normally.
- When trying to make an RS-NOR Latch or other redstone circuits, sometimes the redstone torches burn out unexpectedly.
- If you have a redstone torch on top of a block and powered redstone dust powering the block that the torch is attached to, the torch will not turn off as it should, this seems to depend on the coordinates of the torch. Place the torch somewhere else and it may fix the problem. If the problem persists move the torch to another location, or replace the redstone dust powering the block with a repeater.
- If you burn out a redstone torch, by rapid activation and deactivation, then destroy the torch, replace the torch in the exact place it burnt out, then power it, the redstone torch simply burns out
- In Beta 1.8 the redstone torch will not be turned off if power from redstone dust flows through it. Other power sources (like levers) will still turn them off though IF directly powering the torch.
- In 1.2.3, when placing a redstone torch that's surrounded by blocks except for the bottom, the block that the torch occupies will be at the lowest lighting level. However, only that block will not light up; light will travel out from it. This is also true for Torches.
- If an off-state redstone torch (accessible from Creative item list) is placed, it turns on shortly after, even if not powered.
