Zumtobel as leading luminaire manufacturer world-wide provides a five-year guarantee for its complete product range with effect from 1 April 2010. With this step, Zumtobel lives up to its reputation as a pioneer in terms of innovation, design and quality. The voluntarily extended five-year guarantee comprises Zumtobel's entire luminaire portfolio including ballasts or control gear. Only wearing parts such as conventional light sources or emergency lighting batteries are exempt from the guarantee extension. In case of LED luminaires, the guarantee comprises also the LEDs.

Martin Brandt, COO of Zumtobel AG, explains: "Thanks to Zumtobel's superior design standards, we are the preferred partner for long-lasting lighting solutions that are not influenced by short-lived trends. By extending our product guarantee to five years, we emphasise on our long-term thinking to the benefit of our customers; we belong to the first companies in the luminaire industry to commit ourselves to these high quality standards. In addition to outstanding design, we put a special focus on superior quality in the manufacture of our products. Hence, all Zumtobel plants have been certified according to the ISO 9001 quality standard and have also been awarded relevant certifications according to the ISO 14001 environmental standard."

Especially in view of the rapid development of LEDs, the focus is increasingly shifting to quality and service life. For one of the aspects that make LEDs especially attractive is their service life of up to 50,000 hours. However, these levels can only be achieved if the LEDs are integrated into a technically advanced luminaire with efficient cooling system and sophisticated components.  Zumtobel has the full expertise to develop and manufacture high-quality luminaires featuring state-of-the-art technology and durable design and therefore is able to provide a five-year guarantee for its luminaires.
