A Redstone Lamp is a brownish (when off, and gold when on) block visually resembling Glowstone (due to its crafting materials) that gives off light as long as it is powered. While powered, they have a luminance of 15, one level higher than a torch and the same light level as glowstone. They require constant input in order to emit light. Similarly to other light emitting blocks, they will melt snow and ice.

Een redstone lamp zal oplichten als deze direct signaal van een krachtbron krijgt, of als deze naast een blok staat dat zelf signaal in zich heeft. Het is mogelijk om hendels direct op de redstone lamp te plaatsen, waardoor deze aan gaat.
Een redstone lamp kan zelf ook een signaal doorgeven naar bijvoorbeeld redstone. Als je een redstone lamp breekt, dan zal het niet veranderen in gloeisteen stof (zoals wel gebeurt bij gloeisteen). In plaats hiervan behoud je de redstone lamp
Een redstone-lamp activeert normaal, maar heeft 2 ticks nodig om te deactiveren.
Redstone lamps can be used as an attractive and functional light source. Where the lamps are hooked up to a switch, caution should be used when leaving a room with the lamps off, as mobs will likely spawn in the unlit room. This can be used to the player's advantage; in a trap based on a monster spawner, for example, redstone lamps on a switch can be activated to raise the light level and temporarily prevent mobs from spawning. Similarly, lamps could be turned off to allow growing huge mushrooms, then on again to avoid mob spawning.
Redstone lamps can also be used to create a redstone display as an alternative for redstone torches, which do not emit much light, the player creating such a display however should be aware that each "pixel" is a small cross making straight lines impossible. This can be corrected by making the screen 2 blocks (of any redstone conducting block) thick. Then add levers or some other activator on one side of the display. On the opposite side, only one pixel will be displayed.
Alternatively: to make a solid wall of square 2*2 pixels, this arrangement can be used. The redstone wires exit the back every second horizontal and vertical square, meaning that they can be individually controlled.
A system of redstone lamps wired to a daylight sensor with an inverted signal can be used to illuminate a structure at night automatically. A half day clock can also be used as long as the clock is synchronized properly to spawning light levels of mobs.
Because mobs can spawn on unlit lamps it makes them a great way to make a mob killing system because you can control when you want the mobs to spawn by having the lights on or off. You can also hook up a bunch of lamps to a line of repeaters to make a timed light.
Redstone-lampen kunnen ook worden gebruikt voor automatisch paddenstoel oogsten doordat paddenstoelen "poffen" wanneer het lichtniveau te hoog word.
|Redstone Lamps, originally called Lanterns, were planned crafted objects originally planned to be introduced in the Halloween Update. This feature was delayed because of the lack of time and would have been implemented in a future update.|
|November 11, 2010||On Notch's Twitter account, he claimed (likely as a joke) that "lamps" had actually stood for "Light A-givin' Material Portal Side... the yellow stone thing", probably referring to Glowstone.|
|January 13, 2011||Notch claimed that lanterns were "postponed",|
|January 20, 2011||Notch stated that he was "not sure" when they would be implemented.|
|June 12, 2011||Notch also hinted at adding them, or at least that he's working on them|
|1.0.0||During Minecon when confronted about Lanterns, Notch said that lanterns were scrapped due to the majority of people preferring torches.|
|Later Jeb started working on a Lantern-like idea that will feature a glowstone light source, but will be purely generational as their existence will not change the effects of torches like the Lantern was supposed to do. This idea grew into the Redstone Lamp.|
|1.2.1||12w07a||The Redstone Lamp was introduced. Jeb passively announced the addition of Lamps in a tweet the day before its release in response to another tweet.|
|Originally when released, levers could not be placed directly on redstone lamps to power them.|
|1.2pre||The texture for the off-state lamp was darkened.|
|1.2.4||Previously, breaking a lit Redstone Lamp will yield a lit Redstone Lamp block which does not stack with normal, unlit Redstone Lamps in the inventory. This was fixed as of 1.2.4.|
|When first implemented, hooking a redstone lamp up to a rapid-pulser will strobe the light, causing lag. This was fixed in 1.2.4.|
Before Redstone lamps, Notch wanted to implement an item called the Lantern, but the idea was scrapped and only later reemerged as the Redstone Lamp; however, several differences exist between the two.
With the addition of the lantern, torches would flicker out and need to be re-lit with flint and steel. The lantern would serve as a permanent source of light. According to Notch, when the update would occur, all torches placed on the map, in the inventory, and in chests prior to the update would be converted to lanterns. To do this, the lanterns would use the (former) block ID of torches along with a re-skin.
The glowstone introduced in the Halloween Update was a potential item requirement to craft lanterns, as it has the greatest luminance as a raw material. This would also make lanterns relatively inaccessible and a risky item to get, as has been hinted at by Notch. A second potential item that might have been required to create lanterns was Netherrack, a block that never burns out while lit. Glowstone can be obtained by trading with villagers, and can also be obtained by going to the The nether, along with netherrack.

- In Notch's Ludum Dare 22 contest entry, Minicraft, lanterns can be made in the crafting table.
- If you set the redstone lamp on a timer so it turns on and off and you shoot an arrow at the top or side, the arrow will vibrate while making the sound of the arrow sticking to a block.
- Although it makes the sound of glass (like glowstone and glass pane) when broken, it acts like a solid block.
- Placing a redstone torch anywhere adjacent to the lamp, other than on the lamp itself, will power it.
- Pressure plates, buttons, and levers can all be placed on top of it or next to it, giving it power.
- Unlike redstone torches, rapidly turning lamps on and off will not burn them out.
- Just like TNT, you can have a block above a redstone lamp, and a pressure plate on that, and the lamp will light if the plate is stepped on. This can be an effective warning method.
- Placing one unlit redstone lamp anywhere beside a lit redstone lamp, that is powered directly, will cause the unlit redstone lamp to become lit. (This only happens because the redstone lamp transmits power to the second one.)
- Redstone lamps can be powered by detector rails, making them an interesting material to use for rollercoasters and lighthouses.
- Placing an on-state redstone lamp will cause it to deactivate due to the lack of redstone powering the lamp.
Note that lamps are themselves solid blocks, and so power other lamps. This causes the cross-shaped patterns that you see.
A glowing roof is easy to do - just lay wire across the blocks, or line the top of the lamps with redstone blocks. Floors and walls are also do-able. For a floor, just use the "knight's move" shape underneath the floor with torches. For a wall, use wall-mounted torches that power blocks above them.
