Sea Lantern

Come on! Grow up! This article is a stub. You can help the Minecraft Wiki by expanding this article.

A Sea Lantern is a light source that only appears underwater in and around Ocean Monuments. The sea lantern has an animated texture and gives off a light level of 15. It is one of only four blocks that will give off lasting light if it is placed underwater, the others being Jack o' Lanterns, glowstone, and a redstone lamp. The sea lantern is more powerful than a torch and works on land. The sea lantern can be used like a "beacon" to help players find their way home after long explorations. A sea lantern is used for building a conduit structure, along with prismarine brick, prismarine, and dark prismarine.
