Light blocks cannot be mined, or even targeted, similar to air. They do not attach to any block, meaning that breaking an adjacent block does not remove the light block. However, they can be broken by replacing them with another block. The exception is water (including flowing water) which can occupy the same space as a light block. See this page for details.
A light block is normally used in adventure maps (while most just apply Night Vision or Conduit Power effects). This is also used by teachers to light up assignments. [EE only]
Each light block (as a block or as an item) has an associated light level, which can be anything between 0 and 15 inclusive. In the player's inventory, light blocks display their light level in the top-left corner and appear "brighter" at higher light levels.
Light blocks produce their associated light level.
