Largest lens in a lighthouse (relative to size)

First lit on 1 October 1909, Makapuʻu Point Lighthouse (21.3° N, 157.6° W) on the island of Oʻahu, Hawaii, USA, stands a fairly diminutive 14 m (42 ft) tall but contains a hyper-radial lens that is 3.7 m (12 ft) tall and 2.5 m (8 ft 2 in) in diameter. The supersized glass Fresnel lens, the largest in the USA, occupies more than a quarter (26%) of the structure's internal space.

Containing more than 1,000 prisms, the lens has an intensity of 115,000 candlepower and has a range of 19 mi (31 km).

Hyper-radials were the largest form of Fresnel lens ever made for lighthouses, with only around 30 ever created owing to their expense.
