"1787" . . "The original light at Kinnaird Head Lighthouse was established by Thomas Smith on 1 December 1787. A lantern was set 120 feet (37 m) above the sea on a tower of the old castle. Whale oil lamps produced a fixed light, each backed by a parabolic reflector. Kinnaird Head was the most powerful light of its time, and contained 17 reflectors arranged in 3 horizontal tiers."@en . . . "Kinnaird Head Lighthouse"@en . . "10.0"^^ .
