Work at La Corbière Lighthouse has successfully upgraded its light from a conventional incandescent lamp to a LED system.
The upgrade has replaced a mercury bath system at the top of the lighthouse, which was believed to pose a health hazard and has been gradually phased out from lighthouses in the British Isles.
The 10m (33ft) high lighthouse was the world’s first concrete-built lighthouse and is one of the island's most popular attractions.
The lighthouse was converted to mains electric in 1965 and fully automated in 1974.
A spokesman for the Ports of Jersey, which is responsible for its care, said the work was "sympathetic" to the lighthouse’s history and most of the original mechanisms remain in place.
