Hyperradiant

Hyperradiant fresnel lenses were the largest ever built and were installed in fewer than a dozen major "landfall" beacons around the world. Other recipients include Makapu'u Point lighthouse on Oahu Island in Hawaii, Cabo da Sao Vincente in Portugal, Manora Point in Karachi, Pakistan, the famous Bishop Rock off the coast of Cornwall (in the UK), Abrolhos island off the coast of Brazil and Cape Race, Newfoundland.
