The measurement of the spectral qualities of obtrusive light

The world around us is changing faster than we can recognize. Some changes that are directly related to our lives are not even noticed, but some of them are very intensively perceived and we respond to them. If it is somewhere obtrusive light (light pollution), where is it fault? Is it caused by poorly designed lighting system, the current state of the weather or high content of dust particles and aerosols in the air? The first case is the outdoor lighting system as a source of obtrusive light and second one (night sky) only displayed the obtrusive light and it can be disturbing.
