GENIOL

The Wuppertal-based company Franz Heinze produces petromax lamps and cookers under the brand name Geniol. Heinze was previously a supplier of PETROMAX components. After the sale of the Graetz company (PETROMAX), Heinze took over the distribution. Until the end of the 90s, both Geniol and Petromax lamps were built in Portugal. This tradition lives on in Heinze Metallwarenmanufaktur, which distributes Petromax lamps in addition to home accessories.
