The First Order Fresnel Lens was installed in the St. Augustine Lighthouse in 1874! It came all the way from France. The lens has 370 individual prisms and weighs roughly 2 tons. A 1000-watt light bulb currently serves as it light source, as it has since the tower was electrified in 1936. #staugustinelighthouse #reels #fresnellens #lens #light #view #staugustine #florida #lighthouse #tower #museum #beautiful #saintaugustine #staugustinefl #floridahistory #lovefl #beacon
