Nearly 70 years of experience


Our great technological expertise is based on nearly 70 years of experience. We do not buy in these skills but have them in-house. In the production of conventional halogen lamps and bulbs we use high-tech equipment and the latest methods.

Hard glass technology and quartz glass technology are all part of our know-how. We have our own coil production facilities, a glass processing section and a filling gas plant, where we make halogen gases ourselves. In order to ensure a consistently high level of product quality, we employ the very latest technologies, above all in quality control.

We use non-contact measurement technologies such as camera or light measurement to test our bulbs throughout the entire production process.


The bulbs are put through different tests such as geometric light measurement or a durability test, as well as through special testing as required. Our high-tech capabilities mean we are very well positioned for the global market.
