Light Level Guide

A complete reference to every block that emits light in Minecraft Java Edition, sorted by light level from 15 down to 1. See the exact light value for glowstone, sea lanterns, torches, froglights, candles, amethyst, and every other glowing block, with the state details that matter: only while lit, only with glow berries, brighter with more candles, and only underwater. Includes how block light spreads, the light level mobs need to spawn, and torch spacing for spawn proofing.
