(without reflector shade) The Petromax is probably the best-known light in the world. The name harks back to its inventor Max Graetz, who was known as Petroleum Max. The lamp has been a bestseller ever since 1910, and the extremely heat-resistant borosilicate glass cylinder has always been manufactured by the company Schott. Even today the lamps, which are hand assembled using over 200 individual parts, still cast their spell over people. Fishing boats bring in their nightly catch illuminated by their impressive power of 400W, while world travellers tell stories by their light. Not for indoor using.
