For the tallest ship https://www.ship-technology.com/projects/msc-oscar-container-ship/ in the world, at 239ft, the lighthouse is ~139ft below the horizon at 44 miles out.

And then.... when looking at Pictures of the Lighthouse, suddenly it dawns on you that the BASE is ~~ 150Feet ABOVE Sea Level...

Look at it again. No base.
243Ft focal height. 44 mile visibility.
I just want to see a photo or video of what that looks like at night.
The BASE specifically means the FOUNDATION....
Buildings DO NOT STAND without a Foundation or "BASE"....
There is a Picture of it, on top of a small hill or knoll...
The picture shows the Waterline...
From the height of the Tower, you can estimate the height of the Knoll....
It is about Half of the height of the Tower....
And I'm highly unimpressed with the Fact that you are FUNCTIONALLY ILLITERATE...

He's not illiterate, he's a troll. Stop feeding it.
All the examples show the focal length height.
There are many lighthouses without a base.
