The German manufacturer Holtkötter was founded in 1964 by Franz Holtkötter in Bad Waldliesborn, Westphalia. The hand-made lamps combine excellent lighting quality with fine workmanship. Great importance is attached to meeting high standards and the constant development of innovative lamps. In the manufacture of the lamp, craftsmanship tradition is combined with industrial tradition and almost the entire manufacturing process is carried out by independent hands. Holtkötter has been using the experience gained over decades to design in-house developments with particularly high luminous efficacy in LED technology. As a result, LED modules are sometimes used with such a high light output that would have been unthinkable just a few years ago. The LED technology developed in-house also includes the SunLike LED modules, which produce sun-like, healthy light that is particularly kind to the eyes. In contrast to conventional LEDs, these LEDs have a low blue light spectrum, which considerably reduces the effects of artificial light on the eyes, concentration and biorhythm. These modules are used in the Holtkötter Clea S and Clea T. Some of the Holtkötter lamps use DIM-TO-WARM technology, which changes the colour of the light to a warmer tone when dimming. Numerous other modern LED technologies are also used in the lamps of this German manufacturer.
