The Sultan Shoal Lighthouse (Chinese: 苏丹浅滩灯塔; Tamil: சுல்தான் ஷோல் கலங்கரை விளக்கம்) was built in 1895[1] during the time when the late Commander Charles Quentin Gregan Craufurd (from the Royal Navy) was the Master Attendant (equivalent to the present day Port Master) of Singapore.

[4] Incandescent oil dioptric light with ‘Hood’ burner was used in 1931 with a 3rd Order 500 mm optic.

This optic revolved on mercury, producing an intensity of 670,000 candelas with a visibility range of 22 nautical miles (about 40 km).

[4] The 3rd Order optic was replaced by a rotating beacon, which possessed a revolving array of 24 lamps-cum-reflectors.

Operated by the Maritime and Port Authority of Singapore, the present lighthouse equipment consists of a main and standby rotating beacon, each producing 110,000 candelas with a range of 20 nautical miles (about 37 km).
