ERCO Lichtfabrik is based in Lüdenscheid and is a leading specialist in architectural lighting with LED technology. The family-owned company was founded in 1934 and now operates in 55 countries worldwide with independent sales organisations and partners. The product range has been based entirely on LED technology since 2015. In Lüdenscheid, ERCO therefore develops, designs and produces digital luminaires with a focus on photometric optics, electronics and design. Lighting tools are created in close contact with architects, lighting designers and electrical designers and are primarily used in the following areas of application: work and culture, community and public/outdoor, contemplation, living, shop and hospitality. ERCO sees digital light as the fourth dimension of architecture and supports designers in making their projects a reality with highly precise, efficient lighting solutions.
