The lamps were pioneered by the British Navy in the late nineteenth century and introduced by the Royal Australian Navy after 1918, and continue to be used to the present day. Manufactured in 1960, the Wilsons Promontory lamp was provided to the lighthouse by the Department of Shipping for signalling ships but was also used for communicating with Cliffy Island, 18 nautical miles away. This type of lamp was renowned for its brilliant light, and lightkeepers from the two lightstations ‘used to practice their signalling with each other, as its effective use was reliant on precise positioning of the scope which is located on top of the lamp’. The inside of the case is imprinted with ‘RAN (Royal Australian Navy), and details on the lamp include a serial number, the date of 1960 and the initials of the Department of Transport, which at that time incorporated the Commonwealth Lighthouse Service. Another Aldis lamp and case with a date of 1960 is held at Cape Nelson and third lamp and case is at Point Hicks; (date unconfirmed but possibly 1943). A fourth lamp and case formerly at Cape Schanck disappeared from the collection sometime between 1995 and 2003.Aldis lamp and case (WPLS 0003.2; likely provenance) The lamps are not rare in museum collections however the Wilsons Promontory example has a confirmed provenance to the lightation and has first level contributory significance as a fine example of the Aldis lamps that were distributed to lightstations throughout Victoria and Australia.1.

This portable, hand held visual signaling lamp, with trigger mechanism and inner reflective disk, was used for optical communication via Morse code, with the concave mirror tilted to focus the light into pulse signals. Larger versions of these lamps are fixed on ships or pedestals and have shutters in front of the light that are opened and closed to transmit signals. Smaller hand held versions like the Cape Nelson example have a concave mirror that is tilted to focus the light into pulse signals, and despite their size the lamps were renowned for their brilliant light. Invented by Arthur C W Aldis (1878‐1953) and pioneered by the British navy in the late nineteenth century, they continue to be used to the present day. Details on the Cape Nelson lamp include a serial number, a date of 1960 and the initials of the Department of Transport, which at that time incorporated the Commonwealth Lighthouse Service. Another lamp of the same date which is held at Wilsons Promontory was provided to the lighthouse by the Department of Shipping for signaling ships but was also used for communicating with Cliffy Island, 18 nautical miles away. Point Hicks also has an Aldis lamp and an associated case, which is painted an army green colour. A fourth lamp and case formerly at Cape Schanck disappeared from the collection sometime between 1995 and 2003.

It comprises the metal encased Aldis lamp with electrical cord and its associated green-painted, hinged wooden carrying case, which has a metal clasp and leather hand grip. Larger versions of these lamps are fixed on ships or pedestals and have shutters on the front that are opened and closed to transmit signals. Smaller hand held versions like the Point Hicks example have a concave mirror that is tilted to focus the light into pulse signals via a trigger.

Another Aldis lamp and case remaining at Cape Nelson Lightstation dates to 1960 and has the initials of the Department of Transport, which at that time incorporated the Commonwealth Lighthouse Service. Wilsons Promontory also has an Aldis lamp and case that dates from around the same year. A lamp formerly at Cape Schanck has disappeared. The Aldis lamp and associated case at Point Hicks has first level contributory significance for its historic values and provenance to the lightstation. PHLS0007.1 Hand held signal light.
