Products from DHR
DHR (Den Haan Rotterdam) is a renowned manufacturer of navigation lights, searchlights, signaling lights, and air horns, with a long-standing presence in the maritime industry since the 1920s. The company began by producing brass navigation lights operated by oil and evolved over the years to electric bulb and plastic housings, and now to modern LED navigation lights with anodized aluminum housings. All DHR products meet the highest standards to withstand the harsh weather conditions at sea.
With its own R&D department, DHR continuously develops and tests new products. Once the designs are completed, the toolmaker begins creating a prototype. At the same time, all necessary components, such as circuit boards and lenses, are ordered. Within a few weeks, a fully functioning prototype is made, which then undergoes rigorous testing to ensure it meets the company's high-quality standards. Once the product passes these tests, a production line is set up, and the new product goes into series production.
Since its inception, DHR quickly became known for its high-quality products. This standard is maintained today to ensure that lighting and signaling equipment performs exceptionally well. This is achieved by using only the best materials and keeping production in the company’s factory in the Netherlands, where the entire production process is closely monitored to ensure pristine quality.
Whether it’s an air horn in dense and icy fog, a searchlight in the Arctic, or signaling lights in the Suez Canal, Den Haan Rotterdam manufactures its products to ensure safety at sea in all weather conditions.
