Duncan Geere Mojang avatar.png It's dark at the bottom of the ocean. Black, cold, and full of unseen dangers. But a handful of Minecrafters, those brave enough to delve deep below the waves, have reported seeing lights in that darkness. Just before they're attacked by spined monsters with a single, enormous eye. Aargh!

Sea lanterns are underwater light sources that appear in ocean monuments and underwater ruins.


Sea lantern itself can only be obtained when mined with a tool enchanted with Silk Touch. When broken using anything other than a Silk Touch enchanted tool, it drops 2–3 prismarine crystals. The Fortune enchantment increases the amount of prismarine crystals dropped. This method of obtaining sea lanterns is wasteful though; the 4 prismarine shards and up to 3 of the prismarine crystals used to craft it are non-retrievable.

Light source[edit]

Sea lanterns emit a light level of 15, the brightest possible light level in the game. They produce the same amount of light as glowstone, redstone lamps, jack o'lanterns, beacons, and conduits.

Conduit power[edit]

Sea lanterns can be used to activate a conduit by building a structure around it. By doing this, the conduit will emit 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.
