Light (block)

Lights are invisible blocks, primarily intended for map makers, that can produce any light level from 0 to 15.

Light blocks cannot be mined, similar to air, and can be targeted only if the player is holding a Light item in the main hand. Light blocks with a light level of 0 are functionally identical 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.[1] The exception is water (including, in Bedrock Edition, flowing water), which can occupy the same space as a light block. See Waterlogging for more information.
