Inside the fresnel lens of a lighthouse. (The tallest land-based lighthouse in the UK)

Perspective from inside a 16 sided fresnel lense, with 2 light bulbs visible

Perspective from outside showing the wavy shape of the glass

Cool!

Are their taller lighthouses that are not land-based? Are they floating?

[-] 56_@lemmy.ml 2 points 2 months ago

Well... I've tried to find out just now. Most taller lighthouses are on small rocks in the sea. On some the lighthouse covers the entire rock. I have also discovered that there are potentially taller land-based lighthouses in the uk, this one just seems to be best at advertising it.
