After 1826, the General Mining Association consolidated the various coal mines around Sydney Harbour and greatly increased the shipping of coal to ports on the Atlantic coast.
 In support of this effort, a lighthouse was built at Low Point in 1832 to aid vessels entering Sydney harbour.
 This first lighthouse was built at a cost of £770.
The tower was octagonal, wooden, with its sides painted alternately red and white, 15.54 metres (51.0 ft) high, base to vane.
 During its first winter the lead roof was blown off in a heavy gale and the light was out until the lantern could be replaced with a new iron lantern.
 It was so exceedingly cold that the lightkeeper, Robert McNab, was forced to put pans of hot coals around the inside of  the lantern to keep the light going; it was nearly impossible to keep up a flame from poor-grade oil when the temperature was minus −25 to −30 degrees Celsius (−13 to −22 degrees Fahrenheit).
 In 1856, McNab complained that there had been no repairs or improvements of any consequence in the 19 years of the light's operation.
 In particular, the tiny dwelling required considerable repair, and the light leading shipping into the increasingly busy Sydney Harbour was considered to be inadequate.
 New lamps were supplied immediately, which did improve the light, but it was another seven years before a new octagonal iron lantern was installed, providing the room necessary for larger oil burners and reflectors.

By 1878, it was once again necessary to increase the size of the lantern; to accommodate it, the tower had to be strengthened structurally.
A temporary light was fitted 4.87 metres (16.0 ft) below the lantern deck while new frames and knees were fitted under the gallery deck.
The new iron lantern was 12 sided, 2.95 metres (9.7 ft)in diameter, and able to hold the new lighting apparatus of 13 burners, each with its own 40.6 centimetres (16.0 in) reflector.
A light was first shown from the new lantern on July 13, 1878, and with all the buildings repaired and painted, the station was in first-rate order.

By October 12, 1881 Low Point was a signal station at which the International Code of Signals was in use and was one of two stations on Cape Breton Island of the Maritime Telegraph System .
  The Port War Signal Station was located at the Flat Point Lighthouse during WWI (1917 - 1918) and WWII.

In 1922 a third-order Fresnel double bullseye dioptric lens, group flashing white (5 sec.),
manufactured in France by Barbier, Bénard et Turenne was installed.
This replaced the 1857 fixed white, fountain lamp.

A steam fog-horn was established at this station in 1903, followed by many alterations and additions over the years to the horn and lighting mechanisms as technology advanced.
One of the more serious problems that plagued this station, as it did many others, was erosion.
Through the years, upwards of half a million dollars was spent on building and maintaining the breastworks and cribbing.
