Spectra

The energy balance for most types of UVH lamps is as follows (approximate values):

30 % UV radiation,15 % visible light,55 % infrared (heat)

Depending on the filling of the lamp, whether only mercury or also with iron or gallium or other additives, the radiation peaks shift to different wavelengths. Due to this, the proportions of UV-A, UV-B and UV-C change relative to one another. The three most commonly used UVH lamp types emit the mercury, iron and gallium spectrum.
