If the spectrum of tungsten halogen lamps used in museums and galleries up until now is considered, it becomes clear that this also contains components in the UV and IR ranges, in contrast to the LED spectrum. In addition to fading from excessive exposure to light, UV radiation may also weaken the structure of such things as textiles and wood, may cause chalking on paints and plastics and result in the yellowing of paper. IR radiation on the other hand accelerates the chemical, biological and mechanical disintegration of thermally unstable materials such as wood.
