Petromax was one of the brand names from Ehrich & Graetz. The company used it for their pressurised kerosene lamp (US: kerosene lamp) that uses a incandescent mantle. They are as synonymous with the paraffin lamp in Continental Europe as Tilley lamps are in Britain and Coleman lanterns are in the United States. Today's company Petromax GmbH sells not only pressurised paraffin lamps lamps but also other products for camping and outdoor use.
