LED lighting Calculate online

It reduces energy consumption and CO₂ emissions by up to 80%, is "Made in Germany," and is manufactured to the highest quality and environmental standards. With the longest service life and the highest quality on the market, it is particularly reliable. Thanks to its sustainable reusable system, the GLT LED TUBE is taken back, repaired, or recycled after use, reducing electronic waste and conserving resources. It complies with all relevant EU standards and is the only light source with an Environmental Product Declaration (EPD), which certifies its outstanding environmental performance throughout its entire life cycle.

The GLT LED TUBE is available in various versions to optimally meet different requirements. It is available in all standard lengths from 550 mm to 1800 mm and in various luminous intensities, offering different brightness levels as needed. They are also available in color temperatures of 3000K, 4000K, and 5000K. Different beam angles allow for customized light distribution depending on the application. Thanks to standardized interfaces according to IEC/EN 62776, the models are equipped with standardized bases and are therefore easily interchangeable. The GLT LED TUBE thus offers maximum flexibility and efficiency for a wide range of lighting requirements.

Yes, you can usually continue to use your existing lights during the upgrade. The GLT LED TUBE is designed to be compatible with most standard light fixtures, making replacement simple and cost-effective. This saves you time and money, as no complex reinstallation is necessary.

The GLT LED TUBE has been developed and produced exclusively in Germany since 2011. German LED Tech, a family-run company based in Aspach near Stuttgart, manufactures the lamps in modern, automated facilities under the highest quality standards. The electronics consist of 100% SMD components and comply with all relevant EU standards, including ENEC and EN 62776. Production takes place in compliance with strict environmental criteria, and the site is certified according to ISO 14001:2015.

Yes, the GLT LED TUBE complies with all relevant EU standards. It is certified according to IEC/EN 62776, meets current legal requirements, and has an Environmental Product Declaration (EPD) confirming its environmental compatibility and quality throughout its entire life cycle. They enable a future-proof, maintenance-friendly lighting system – completely independent of any manufacturer (no single sourcing). This allows you to remain flexible and independent.

Yes, you can rent the GLT LED TUBE. This way, you benefit from fixed, predictable rental rates without high initial investments, conserve your liquidity, and save time and money by eliminating complex purchasing and administrative processes. The savings in operating costs usually fully cover the rental rates. This way, you maintain full cost control with maximum transparency.

Choose from various rental models to suit your needs. Starting from 12 months.

When you purchase, you receive a three-year warranty. When you rent, you benefit from a functional guarantee that applies for the entire rental period – including planning, retrofitting, and maintenance. Light as a Service from GLT offers comprehensive support with no hidden costs or risks.

Save up to 80% energy and CO₂ – permanently. The GLT TUBE is "Made in Germany," is recycled through a reusable system, and reduces electronic waste. As the only light source with an EPD (Environmental Product Declaration), it offers verifiable environmental performance over its entire life cycle – ideal for sustainable construction according to DGNB, LEED, or BREEAM.

At the end of the GLT LED TUBE's service life or rental period, the GLT LED TUBEs are taken back, repaired, or the raw materials are recycled. This actively contributes to reducing electronic waste and conserving valuable resources.

When you purchase a new GLT LED TUBE, you will receive a refund of €5 per unit when you return your old GLT LED TUBE. This return system is unique in the LED market and promotes the sustainable use of lighting technology.

For fixtures with a conventional ballast, replace the starter with a dummy. Then install the GLT LED TUBE in place of the old fluorescent tube.

The installation of a GLT LED TUBE into an electronic ballast fixture must be performed by a specialist. Thanks to the direct power supply of the GLT LED TUBE, the interference factor of a ballast is eliminated, increasing operational reliability.
