 The original apparatus was a 10 feet (3.0 m) H Wilkins & Co. catadioptric. The light source was twelve kerosene lamps with a parabolic reflector for each lamp, on a revolving iron frame, in four groups of three. Two groups were white and two groups were red, resulting in a light characteristic of an alternating red and white, with intensities of 500 cd and 200 cd, respectively. It was originally manned by three keepers.
