Label

Labels are intended to be used to label the contents of chests or other containers, though they can also be placed standalone. When right-clicked, the label will forward to the container it is attached to (if applicable). The label itself can be accessed by shift-right clicking.

When a light-emissive block (such as Glowstone) is placed in a label, the label will also emit that block's light level. If multiple light-emissive blocks are placed in a label, it will emit the sum of their light levels, capped at 15.
