Lighthouse

We are away for a few days in Norfolk, staying in a lighthouse keeper's cottage at Cromer.  This is the view from our bedroom window.  Fortunately the light points the other way, so will not disturb us at night, and there is no foghorn (and, incidentally, no fog).

The current lighthouse was built in 1833.  The tower is just 18m high, but is on the cliff top so that the light is 84m above mean high water.  I was surprised to learn that the lamp is quite small and just a 150 watt metal halide bulb which is changed once every 5000  hours. As it burns continuously, that is once every 30 weeks, or thereabouts.  It produces 294,000 candela and can be seen for 21 nautical miles.

As there is no wifi or wired internet here and the mobile signal is weak and unreliable, I will have to backblip the images from our stay here.
