Dynamic Lite Light

Items and entities emit light when they are held in the hand, worn on the head or body, placed in an item frame, or dropped on the ground. Light is anchored to the center of the source, so a light held in the hand sits at the entity's eyes and most other cases place it at the center, while the remaining cases use the feet. A global setting controls how often the light position updates, and glow squids emit light as well.

The mod reads its behavior from two data pack paths: a light level file that lists entity type tags with an emitted level, and a water sensitive file that controls which items and entities stop or start emitting light in water. Some items and entities emit light only when they are out of water. Fifteen independent entity type tags extend the light level path, so server owners can add entries without editing the mod.
