One of Australia's rarest brands, Lugon, was a totally independent operator based in Melbourne.
Facts are difficult to come by, but they had at least two, if not three, plants across that city.
Although this example is a Low Voltage, 32v, 75w model, they are butter known for their Automotive Lamps, but they made 240v GLS and T12 tubes too.
The plants were located in the Melbourne suburbs of Carlton, Abbotford and South Melbourne. All have been demolished, but the one in Carlton was the last to go, only about five years back. I suspect one plant did the GLS and lamps like this one, another did the T12, and the third did the small automotive they were most remembered for, but determining which was which is very difficult. Carlton possibly had the greatest floor area. South Melbourne has been so built over and gentrified no trace remains, not even the section of street it was on!
One really unique feature of the full sized Lugons was the "ripply" shoulder near the base rim and butt-seal point. Most other Australian Lamps had a nice smooth cone on the shoulder.
