On This Day in Trinity House History – 8 December

1858

Electric light introduced into South Foreland High Lighthouse

In 1858 South Foreland High Lighthouse became the first in the world to exhibit an electrically-powered light, made possible by Trinity House’s Scientific Advisor Professor Michael Faraday and his colleague Professor Holmes. They believed that electricity could effectively power a lighthouse light and so installed Holmes’ magneto-electric machine.

The experiments were a success technically, but electricity proved too costly as a power source, so Trinity House lighthouses continued to use mineral oils for some decades longer.
