The lighthouse is located on the uninhabited Rathlin O'Birne Island which lies two kilometers to the west of the Malin Beg coastline at the southwestern tip of Donegal, making it County Donegal's westernmost point.
In 1974 it became Ireland’s first and only nuclear powered lighthouse. However, by 1987, the power output of the nuclear generator had dwindled to an insufficient level and the lighthouse was converted to wind power, which was in use until 1991, at which point it was converted to solar power.
