Redstone Lamp

The Redstone Lamp first appeared in snapshot 12w07a. It is the first block to have a toggle-able bright light level.

When powered by Redstone it will emit a light level of 14, just like a Torch. It is off by default so placing this as a source of light is useless unless you have redstone to power it. Like other light-emitting items and blocks, Redstone Lamp will melt snow and ice. Unlike Glowstone, fences will attach to it, making it good for making street lamps.

Bugs

 * Powering multiple Redstone Lamps at a time may crash your game.
 * Because it acts as a solid block that can transmit power and also receives power, the following is possible: http://img210.imageshack.us/img210/9126/lampgi.png
 * A power source can be on the same y coordinate to power, one above, or two above (redstone on top of a block on top of the lamp).

Trivia

 * Although it makes the sound of Glass (like Glowstone), it acts like a solid block.
 * Placing a Redstone Torch anywhere adjacent to the lamp, other than on top, will power it.
 * Pressure Plates, buttons, and levers can all be placed on top of it or next to it, giving it power. Levers underneath Redstone Lamps will also provide power when switched on.
 * It can be pushed and pulled by pistons.
 * Detector Rails with a minecart placed next to the lamp will activate it.
 * Breaking a Redstone Lamp when it's turned on will give an item that looks switched on, but will still be off when you place it.
