Research has shown that LED lighting is mértélben disrupts our sleep-wake cycle, where appropriate, to be used in place of coffee. Now it turns out that LED lights used in expensive paintings conservation seriously damage the paintings.

The three shades of chrome yellow, lemon-, medium-and primrose have a strong X-ray radiation in Germany Deutsches Elektronen-Synchrotronban (DESY) in France and the European Synchrotron Radiation Facility (ESRF). It was found that the medium yellow unchanged remained stable until the citric and primrose become unstable.
The LED light source emits more blue / green light than a standard light sources - written by a professor of ESRF website. However, that blue / green light emitted by the LED bebarníthatja or olive green to darken the colors.
Therefore, the researchers recommend those museums that have paintings that are owned by incorporating such dyes to urgently put these pictures unique perspective, because in addition to these relatively quickly bourgie darken in color.
