For decades, the lighthouse on Bad West Island in the UK has been the navigational coordinates of the Irish waters, with a light beam of 89,900 candlelights illuminating the sea 22 miles away at night. This month, the staff of the Pilot Guild closed the light of the lighthouse as it was preparing to replace the lighthouse's lighting fixtures with energy-efficient LEDs. In addition to energy saving considerations, there are other factors in the replacement of the lighthouse. Since there are no other strong light sources near this area, a large number of birds will instinctively fly towards the lighthouse at night, which also forms the wonder of a large number of birds on the island of Badesi. There have been records showing that there are sometimes 40,000 birds that can be inhabited on the island overnight. However, the staff of the local animal protection organization also said that many birds will die when they fly to the lighthouse during the night due to collision with the building structure. Staff Steven. Stanfield said that after the lighthouse's luminaires were replaced with LEDs, they would be navigated with red light that would not attract bird attention in order to reduce bird mortality. Of course, this way, Badesi will also lose the view of the birds.
