Sustainability
Our daily business is driven by our mission to drastically reduce energy demand in Europe through efficient and circular lighting, to increase the profitability of businesses and to promote a circular economy. That is why we produce exclusively in Germany and design our GLT TUBES to be energy-efficient, durable and recyclable. In this way, we want to make an important contribution to achieving the European climate targets. This sustainability strategy is firmly anchored in our company DNA.

Quality and maximum energy efficiency
Our brand product, the GLT TUBE, is ENEC-certified according to the international standard IEC/EN 62776 for LED tubes for temperature ranges between -40°C to +70°C and can claim the title of "best technology available on the market" according to the current eco-design guidelines of the EU. This means immediate savings of up to 80% in operating costs and CO2 emissions compared to conventional fluorescent tubes. Thanks to this outstanding quality and durability, we have been offering intelligent and flexible rental models for more than 10 years. These enable immediate savings without tying up capital.
Circular Lighting
The GLT TUBE is manufactured exclusively in Germany and is 90% recyclable. Whether you buy or rent - at the end of the service life or at the end of the rental period, we take back the GLT TUBES, repair them or return the raw materials to the cycle. The reusable system of the GLT TUBE is unique on the LED market and directly benefits our environment.

Fraunhofer IBP confirms benefits
A study completed in May 2022 by the Fraunhofer-Institut für Bauphysik IBP on behalf of EnBW Energie Baden-Württemberg AG confirms the advantageousness of the GLT TUBE using the example of the GLT TUBE 150 in the impact category EF3.0 Climate Change compared to comparable competitor products. Compared to fluorescent tubes, the GLT TUBE is already beneficial after 15 days, compared to LED tubes after 101 days. The energy efficiency and resource efficiency of the GLT TUBE is particularly emphasized. You can see a summary of the study here.study here.
