         * Conduit
         * Glowstone
         * Jack o'Lantern
         * Lantern
         * Lava Bucket
         * Shroomlight

         * End Rod
         * Glow Berries
         * Torch (not underwater)
     * Hold these for 10 light level:
         * Crying Obsidian
         * Glowstone Dust
         * Prismarine Crystals
         * Soul Campfire (not underwater)
         * Soul Lantern
         * Soul Torch (not underwater)
     * Hold these for 7 light level:
         * Blaze Powder
         * Ender Chest
         * Ender Eye
         * Glow Lichen
         * Redstone Torch (not underwater)
         * Sea Pickle (only underwater)
     * Holding a magma block produces no light (ignore the video).
* Only air blocks and water source blocks will make a light.
     * So if you're in eg. tall grass or kelp when you switch to a light, it won't turn on and destory the block you're in.
     * However, if you enter grass/kelp/whatever while holding a light, the previous light block will stay on as long as your light is still equipped, so it doesn't randomly flick off when you're running about.
* In v1.2, sculk sensors will sense marker entities dying that are required for the datapack to function. Vote for the bug here.
