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.

In Java Edition, light blocks are available in the Creative inventory. Across both Java Edition and Bedrock Edition, they can also be obtained by using commands such as /give. Using /give <target> minecraft:light[block_state={level:"<int>"}] can give a light block with a specific light level and corresponding texture. If the block_state component is removed or the level is not an integer from 0 to 15, the yellow stars texture is used by the item model, and a light level of 15 is emitted when the block is placed.

In Bedrock Edition, specifying the data value from 0 to 15 determines the block's light level; if the data value is not specified, the light block emits a light level of 0. The command is: /give <target> light_block [amount: int] [data: int (0 - 15)] [components: json].

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.

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).

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 in Bedrock Edition they can be pushed and pulled by pistons.

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