Note on back of case 'Mr. Fred Holmes. Inventor of Dynamo for Lighthouses'. Frederick Hale Holmes pioneered the electrical illumination of lighthouses in the 1850s and 60s. He was the first to use a magneto to supply an arc lamp, in 1853. In 1856, he patented a system to use the magneto to light a lighthouse, which was demonstrated to Faraday in 1857 at Blackwall.
