the secret life of Lighthouses
on prime well done - really interesting and incredible in many ways. Highly recommended ..more than one season.
One of the striking thing was a 3 watt LED replacing 1,000 watt incandescent.
Another, Michael Faraday developing an alternative to the dangerous clunky batteries of the time and making the first electrical generator.
The carbon arc lights that resulted allowed the beam from the light house to be seen clearly in France !!!
Very well done and informative docu that is engaging.
