Redstone Lamp

EDIT: This is out of date.

A redstone lamp is a block that produces light when activated with a redstone signal.

Natural generation
Redstone lamps generate naturally in ancient cities.

Breaking
A redstone lamp can be mined with any tool or by hand, dropping itself as an item.

Usage
A redstone lamp can be used to produce switchable light.

Redstone lamps are redstone mechanisms and can be activated by:
 * An adjacent active power component, including above or below: for example, a redstone torch (except that a redstone torch does not activate a redstone lamp it is attached to), a block of redstone, a daylight sensor, etc.
 * An adjacent powered block (for example, an opaque block with an active redstone torch under it), including above or below
 * A powered redstone comparator or redstone repeater facing the redstone lamp
 * Adjacent powered redstone dust configured to point at the redstone lamp (or on top of it) or directionless; a redstone lamp is not activated by adjacent powered redstone dust that is configured to point away from it.

A redstone lamp activates instantly, but takes 2 redstone ticks to turn off (4 game ticks, or 0.2 seconds barring lag).

An active redstone lamp produces block light 15. An inactive redstone lamp produces no light.

A redstone lamp acts like an opaque block; it blocks sky light, mobs suffocate in it, and it conducts redstone power.

Trivia

 * Multiple tiled redstone lamps produce a pattern that resembles the truncated square tiling t{4,4}.
 * Redstone lamps are transparent on maps.
