FOWEY ROCKS LIGHTHOUSE, FL. In 1931 Fowey Rocks’ kerosene powered classical lens was electrified, its candlepower increased and a flashing characteristic established using a metal screen that revolved inside the lens. The light was automated in 1974 and its old Fresnel has been replaced by a high intensity optic powered by solar charged batteries. That system was installed after an unsuccessful testing of a windmill driven generator.
