LTT – Your specialist for lighting technology
We have been manufacturing high-quality luminaires at our plant in Tettnang on Lake Constance since 1982. Our luminaires are proudly “Made in Germany”.
Our wide range of products includes covered moisture-proof and surface-mounted luminaires for a variety of applications, as well as the development and production of customised special-purpose luminaires in line with customer requirements.

Sustainability
Our products are highly resistant to chemicals and do not age due to environmental factors such as UV light, temperature and oxidation. In addition, all components are interchangeable.
DIN-approved
All our lights comply with current standards and guidelines. The manufacturing and testing processes are integrated into DIN ISO 9001 + new DIN ISO 14001.
Quality
Plastics processing is our business. We have extensive knowledge of materials and processing with the corresponding production facilities.
Efficiency
Our products comply with all current energy directives. With us, high energy savings are not lost, but are efficiently converted into light.
