Heart Lantern

The Heart Lantern is a low light producing item that can be placed on ceilings, like Chinese Lanterns, Star in a Bottle, or any of the Chandeliers. Standing within about 48 tiles of a heart lantern provides a boost in health regen by means of a unique buff, similar to the one granted by campfires.

This item is also a viable light source for purposes of NPC housing despite its low light level.
