South Gare Lighthouse was built in 1884 at the end of the breakwater at South Gare north west of Redcar in North Yorkshire and in north eastern England. == History == There already were two navigation light towers built in 1829 and operating in Durham county at Seaton Carew and another at Hartlepool to guide ships clear of Coatham Rocks off Redcar and then onto the Fairway Buoy outside the bar of the River Tees. The building of South Gare lighthouse was planned and supervised by John Fowler, engineer to the Tees Conservancy Commissioners.〔(【引用サイトリンク】work=Images of England )〕 Both light systems were used until 1892 when use of the light towers at Seaton Carew was discontinued by the Tees Conservancy Commissioners. The South Gare lighthouse light was originally lit by a paraffin wick lamp. and perhaps subsequently by a pressurised paraffin burner.〔 This was removed in 1955, and in about 1980 the chimney and weather vane were removed.〔 The paraffin lamp was replaced by a mains powered 500 Watt tungsten filament Incandescent light bulb with a backup bulb on the bulb changer that operated with a backup diesel generator.〔 The light operated with a 1.5 s flash every 12 seconds.〔 The lens rotation mechanism was originally powered by a clockwork motor but this was replaced by two electric motors, i.e. one duty motor and a backup motor.〔 A fog signal was mounted to the west of the lighthouse but this has evidently been removed. The light source was a 35 Watt CDM-T lamp〔 until 2007 when it was replaced by a 45 Watt high intensity LED lamp. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「South Gare Lighthouse」の詳細全文を読む スポンサード リンク
