The octagonal brick tower now rises 145 feet above ground and 144 feet above water, exhibiting a fixed white electric light of 70,000 candlepower from a first-order lens visible for 18 miles. [(1)] [(2)] [(7)]
HAWAII
KILAUEA POINT LIGHTHOUSE
On the northernmost point of Kauai Island.
This important landfall light, providing a leading mark for ships bound to Honolulu from the Orient, was built in 1913. The tower is of reinforced concrete, and is but 52 feet high, but it stands on a cliff which elevates the light to 216 feet above the water. The moving parts of the lens weigh 4 tons, and this mass turns on a mercury float, making a complete revolution every 20 seconds and giving each 10 seconds a double flash of 1,000,000 candlepower. The lens was built in France and cost about $12,000. Kilauea Lighthouse is also a radio-beacon station providing radio signals for the guidance of ships.
This light was the first landfall made in the first flight by aeroplane from the Pacific coast of the United States to the Hawaiian Islands, in 1927, it being picked up from the air at a distance of 90 miles. [(1)] [(2)]
HAWAII
MAKAPUU POINT LIGHTHOUSE
On the eastern extremity of Oahu Island.
All the commerce from the west coast of North America bound to Honolulu passes Makapuu Lighthouse. The largest lens in a lighthouse of the United States known as a hyper-radiant lens, is in use at this lighthouse. The inside diameter is 8½ feet, sufficient for several men to stand within. Although the tower is only 46 feet high the light is 420 feet above the sea. The 115,000 candlepower light can be seen for 28 miles. The effectiveness of this lighthouse has been greatly increased in recent years through the establishment of a radiobeacon at the station. The radio signals may be heard two hundred and more miles at sea. [(1)] [(2)]
