It can't. Do you still trust pedivikia? Check other ligthouses with same focal height, and you will find that they have twice less range. Just dumb wikipedos don't check their "reliable sources" because usually can't even make a simple calculation. May be they find somhere a "reliable source" where was mentioned a diameter of covered area, and blindly copy that figures to pediwikia.

I have a Pdf book on lighthouses that quotes similar lighthouse height and light distance stats.

25Mb pdf http://library.lol/main/6FDEAF38C0F132578E3F67BBABEED88E

Nice book, but there are only date and height for each lighthouse.

Found only

The building is thought to have been almost 500 feet tall, with a light visible from 35 miles away

about Faros lighthouse, where range and height perfectly fit each other.

Yeah there are other more detailed lighthouse books. In the usual pirate zones. Anyway. The stats are referenced some with pdfs.

https://en-wikipedia-org.turbopages.org/en.wikipedia.org/s/wiki/List_of_tallest_lighthouses

The real question is the angle of the light and video photo evidence of what the light looks like from 44 miles out. Or more typically, they say 29 miles out.

Found interesting note on range in full pedowikia article - https://en.wikipedia.org/wiki/Calcanhar_Lighthouse#cite_note-2

According to List of Lights. "Perobas - Touros" says "22 nautical miles (about 37 km)" which is an incorrect unit translation.

OK, 22 nautical miles is 40km, not 37, but that range seems to be correct. But they still leave wrong range in characteristics section.
