For placements where light pollution is of prime importance, such as parking lot, or a large city nearby, low
pressure sodium is preferred by all municipalities and townships. Such lamps emit light on just one dominant
spectral line (with other far-weaker lines), and therefore is the easiest to filter out. One consequence of
widespread public lighting is that on cloudy nights, cities with enough lighting are illuminated by light
reflected off the clouds. As sodium vapor lights are often the source of urban illumination, this turns the
sky a tinge of orange. If the sky is clear or hazy, the light will radiate over large distances, causing
large enough cities to be recognizable by an orange glow when viewed from outside the city.
