Minecraft wiki entry for Light_Block, associated text: Light blocks are not in the player's Creative inventory. They can be obtained using commands such as /give. 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]. In Java Edition, using /give <target> minecraft:light{BlockStateTag: {level:"<int>"}} can give a light block with a specific light level and corresponding model. If the level is below 0, the non-bulb texture is used, and above 15 the level 15 texture. If the block state is not specified or not between 0 and 15, the light block emits a light level of 15.
