The height of the fire is the vertical distance between the light source of a beacon and the sea level . It is made up of the height of the building and the geographical height of the base. In contrast, the height of the fire carrier only indicates the height of the fire carrier, i.e. the construction supporting the beacon (building, steel mast, etc.).
In seafaring, the height of the fire is decisive for the nautical visibility , i.e. from what distance you can see a beacon with good visibility and sufficient luminosity ( range ) despite the curvature of the earth .
