Light (block)

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

Usage

Each light block has an associated light level, which can be any value from 0 to 15. In the player's inventory, light blocks display their light level in the top-left corner with a unique sprite for each light level.

Placement and Interaction

Light blocks are mainly used in Creative mode, so the description below mainly applies to that mode. Light blocks are not visible, and have no hitbox unless the player is holding another light block in their main hand. When the player holds a light block, any placed light block become interactive, displaying a small icon in the center indicating the block's location and current light level. The block icon is a particle, and does not become visible if particles are set to their lowest setting, although the hitbox remains visible and interactive until the light block leaves the player's main hand. When holding a light block in the main hand, clicking 'use' on a light block that is already placed on the ground causes the light level of the light block to increase by one. If the light level is already 15, it resets to 0. If a light block's level has been modified, it can be copied back into the player's hotbar by using the 'pick block' button while holding another light block. In Survival mode, a light block can be placed, however only its hitbox is visible, and the block is not interactive (it does not allow to increase its level). In Adventure mode, a light block cannot be placed, and already placed blocks are completely invisible and inaccessible (only the light they produce is visible).

Behavior

Liquids such as water and lava cannot pass through light blocks unless they are waterlogged (either with the debug stick or by placing water on either side of the block.) but falling blocks like sand, gravel, and anvils pass through the Light block as if it is air. If a falling block lands on a light block, or another block is placed over it, the light block is destroyed. Light blocks are detected by observers, and they can be pushed and pulled by pistons.

Light source

Since light blocks produce light, their primary use is to illuminate certain areas of the world.
