Production

All Cosmedico UV low pressure lamps are manufactured at our own production plant NARVA Lichtquellen GmbH + Co. KG in Germany. We also manufacture UV high pressure lamps in Germany, e.g. at NARVA G.L.E. The development and production of special lamps for tanning is our core competence. Technical know-how, experience and research are all included in our state of the art products.

Glass

Did you know that special additives in the glass furnace increase the filter effect of the glass and thereby reduce UVB irradiation? This is called “closed” glass. In the case of “open” glass, the filter edge is mainly in the short-wave range and a higher proportion of UVB radiation is transmitted.

Phosphors

UV phosphors are powders, e.g. based on silicates or phosphates that are stimulated by irradiation to emit UV light. For an optimal tanning effect, phosphor blends with sun-like spectra are developed. For particularly high requirements, such as the 10K100®PLUS product line, a special phosphor blend with a unique protective coating is used.

Phosphor mixture

The inner coating of a tanning lamp is blended from several UV emitting phosphors. The phosphor blend is the key factor for the spectrum which determines the tanning effect of the lamp. The important step is to combine the phosphors in a way that they are compatible and stable while providing an optimal tanning effect.
