Iron Lamp-post

Provides a good amount of light.
Overview
The Iron Lamp-post is a crafted lighting item that can be held or placed to provide light. It is one of the strongest craftable light sources in the game, and unlike braziers it is always on rather than toggleable. The lamp-post can be placed indoors or outdoors, and it can even be used in places such as the Mines.
When placed, the Iron Lamp-post casts light in a radius of about 7 tiles, with most of the illumination concentrated in the nearest few tiles. It is therefore useful for lighting paths, work areas, barns, sheds, and other dark spaces where a stronger and steadier light source is wanted. Because it provides more light than any other craftable lighting item, it is a good choice when maximizing visibility matters more than decoration.
- The Iron Lamp-post can be held or placed as needed.
- It may be removed by striking it with a Hoe, Pickaxe, or Axe.
- It works both indoors and outdoors.
- It is always active and does not need to be switched on.
- It provides more light than other craftable lighting options.
Its main advantage is reliability. Once placed, it does not need attention and will continue lighting the area day and night. This makes it especially convenient for farm layouts, storage areas, and cave exploration setups where a permanent light source is preferred.
Because it is a craftable item, players can obtain the recipe and build more than one if they want consistent lighting in multiple locations. Its strong light output also makes it a practical upgrade over smaller decorative lamps or weaker sources when visibility is the priority.
