=== Breaking ===
{{See also|Fortune#Discrete random}}
A sea lantern can be obtained only when mined with a tool enchanted with [[Silk Touch]]. When broken using anything other than a Silk Touch [[Enchanting|enchant]]ed tool, it drops 2–3 [[prismarine crystals]]. The [[Fortune]] enchantment increases the number of prismarine crystals dropped. This method of obtaining sea lanterns is wasteful though; the 4 [[prismarine shard]]s and up to 3 of the prismarine crystals used to craft it are non-retrievable.

{{breaking row|horizontal=1|Sea Lantern}}

Each level of Fortune increases the maximum number of prismarine crystals dropped. The amount is capped at 5, so Fortune III simply increases the chance of getting 5 crystals.

=== Natural generation ===
Sea lanterns generate throughout [[ocean monument]]s, as well as in some [[ocean ruins]].

{{Block distribution}}

== Usage ==
=== Light source ===
Sea lanterns emit a [[light]] level of 15, the brightest possible light level in the game.

=== Conduit power ===
{{main|Conduit}}
Sea lanterns can be used to activate a [[conduit]] by building a structure around it. By doing this, the conduit emits the [[Conduit Power]] effect in a certain radius, depending on how many blocks are used to power it. [[Prismarine]], [[dark prismarine]], and [[prismarine bricks]] can also be used for this purpose.

=== Note Blocks ===
Sea lanterns can be placed under [[note blocks]] to produce "Clicks and Sticks" sound.

=== Transparent block ===
The Sea lantern blocks all sunlight, players and mobs suffocate inside it, and it blocks a [[beacon]] beam, preventing the Beacon's activation. However, like transparent blocks, it does not prevent the opening of chests, monsters (including [[Slimes]]) cannot spawn on it, and it does not transfer a redstone signal. This behavior also occurs in [[glowstone]].
