Naturally, the size of the whole system (in combination with the brightness of the light source) determines the overall brightness and the largest optics were installed in lighthouses called landfall lights. These were lighthouses located at the extremities of the major ocean crossings. Thus, a ship that had been crossing oceans and major seas for many days would catch first sight of a landfall light and this was a very popular and comforting thing for both sailors and passengers to see. The greatest brightnesses and visible ranges were called for here.
Examples of landfall lights are Bishop Rock (England), Cape Race (Newfoundland) and Cape Ottway (Australia).
