e know all about plant lighting.
Whether assimilation fixtures with full spectrum and high pressure sodium lamps or modern LED technology: There are 30 years of experience in supporting horticulture businesses.

Since 2004 we supply customers with luminaires from our own manufacturing.

The company is headquartered in Wülfrath and thus in the catchment area of the big cities Düsseldorf, Essen and Wuppertal. The manufacturing only takes place in Germany because we are convinced that only “made in Germany” guarantees a constant quality of the products.

We are constantly working on new technologies for the exposure of plants. In doing so, the latest research results are always incorporated in terms of the diverse interrelationships between exposure, energetic concerns and growth. In the development of new luminaires and systems, we work closely with the leading manufacturers of lamps and LEDs. Only components from Germany or Europe are used.

Urban gardening: farming new identified

With our solutions for plant lightings new prospects are provided for fruit and vegetable cultivations. In this context an important keyword is urban gardening or urban farming. While the agriculture sector is concentrated in effective cultivating large areas the urban gardening also uses small areas for agricultural purposes. The dominating role here is the sustainability and the environment-friendly production but also the individual self-sufficiency.

Similar to the local electricity production the urban gardening is focused on local food production for the regional demands. The key factors here are greenhouses – and an intelligent plant lighting – to optimize the earnings with limited spaces and use resources.

And not least urban gardening follows the new trend to consider more about food and its production. Above this the fruit and vegetable cultivation contributes to the microclimate’s improvement and plays an important social role in the long-term development of the urban community.

Our vision is to support urban gardening with our technical solutions and our know-how and therefore bring back the fruit and vegetable cultivation to Germany. As a specialist in urban gardening we also advise URBANFARMERS from Switzerland who analyses this issue for many years. Watch our film for this purpose: DH Licht Film.
