Light
minecraft:lightThe Light block is an invisible block intended for map makers, capable of emitting any light level from 0 to 15. It is only obtainable through the creative inventory or commands such as /give, and it lets falling blocks and water pass through it as if it were air. Holding the item in hand reveals placed light blocks as particles showing their configured level.
