Carsten Teller: Why do you need double helix in the truck sector? For normal cars you also make extremely bright lamps, the H3 or H7, for example. And these are single coils.
Jörg Hochmuth: The brightness is not the point. Trucks, for example, are operated with 24 volt on-board voltage. But you can not do that with single coils. Even the wire thicknesses with a simple tungsten wire do not stand up to it. They burn through you. That is, you can not guarantee the demands on durability and reliability with single-coils. For this you absolutely need double helix technology – this is the measure of all things.
Carsten Teller: Added to that is the vibration and shock resistance in the truck sector.
Jörg Hochmuth: There are a number of international standards that we have to meet in order to obtain the necessary certifications in each country. They are Bulb Deflection tests, but also vibration tests and others. We have labs and test tracks for all these tests. These include lighting, performance and durability tests. All our lamps are cyclically subjected to these tests. Some equipment is also booked by other scientific institutes if we have spare capacity.
Carsten Teller: Not only at scientific institutes you have a good name for your work – apparently also with your competitors.
Jörg Hochmuth: Right, that’s the way it is. In this case, competition also enlivens our business. I’ll say it metaphorically: If the global players, I do not want to name names now, the lights go out, then go to vosla. In automotive lighting, we create up to 32,000 halogen lamps per day with our 4.000 series. All made with the same precision. This means that we can cover every production bottleneck of our competitors without hesitation. And we do that regularly.
Carsten Teller: As a specialist for the automotive industry, vosla ensures extremely tight production tolerances and therefore perfect light for set makers and car makes directly. Who benefits from your claim to perfection?
Jörg Hochmuth: We also supply the premium segment of spare parts dealers and therefore also workshops. They are also happy to recommend a superior product with a clear conscience. In the end, the customer always wins.
Carsten Teller: Mr. Hochmuth, thank you very much for this interview.
