Redstone Lamp

Template:Future

A Redstone Lamp is a golden block visually resembling Glowstone (hence 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.

Behavior

A Redstone Lamp with a switch placed on it will behave just like a standard solid block, meaning that if a Redstone Lamp is powered, it will power the block adjacent to it. It will also power Redstone wire if it is placed on top of, underneath, or directly next to the lamp following the same principles as a standard solid block. Unlike Glowstone, when a Redstone Lamp is broken it will not break into Glowstone Dust or Redstone Dust. Instead it will yield one Redstone Lamp, just like a standard block.

History

The Redstone Lamp was introduced in Snapshot 12w07a on February 15th, 2012. Jeb passively announced the addition of Lamps in a tweet the day before its release in response to another tweet.^[1]

Bugs

Redstone Lamps placed outside and turned on can cause performance drops, which are especially noticeable on lower end computers.
Breaking a lit Redstone Lamp will yield a lit Redstone Lamp block which does not stack with normal, unlit Redstone Lamps in the inventory. Placing the lit version away from a Redstone power source will instantly unlight it, allowing it to drop normally and be stacked with other unlit Redstone Lamps. This is likely due to it being two separate blocks, to be compared with Redstone Ore and glowing Redstone Ore.
Because it acts as a solid block that can transmit power and also receives power, it is possible for a Lamp to power another Lamp, or any other redstone device. [1]
Activating a Redstone Lamp in Survival Multiplayer (SMP) will only make it glow and not emit light. The only way to make it emit light in SMP, is to replace the Redstone Lamp. But when you turn off the power to the Redstone Lamp and retry, it will not work.

Trivia

Although it makes the sound of Glass (like Glowstone and Glass Pane), it acts like a solid block.
With the addition of this block you can now create a controllable light source.
It's a solid block; so it can transmit power through just like most other solid blocks. This includes repeater, and vertical redstone torches.
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.
It is believed to be a replacement for the Lantern.
It is also the first crafting recipe to use more than one Redstone dust, as well as being the first that uses the Glowstone block as an ingredient.
