Monuments and effect lighting

Illumination of monuments and the lighting "for effect" is a very controversial theme. On the one hand, we would be pleased if the monument or some interesting thing was illuminated intensely or even in different colors, on the other hand, there are many science disciplines, as well as nature conservationists and the natural night darkness who would prefer to see everything at night in the dark as it was before the advent of technical civilization. We always try to illuminate everything efficiently and interestingly, but in doing so, to avoid unnecessary lighting for people in windows, into nature and into the upper half-space.
