Below are a few sources that contribute to light pollution. There are many potential causes of light pollution. Where appropriate, lighting schemes could include ‘dimming’ to lower the level of lighting (e.g. Another source of light pollution comes from advertising lights.

In combination with optical good practice aimed at limiting light pollution, efficient lamp and luminaire selection are important considerations to minimise energy use and associated carbon emissions. It is affected by the quantity and directional attributes of the source. In particular, some types of premises (including prisons, harbour premises, airports and transport depots where high levels of light may be required for safety and security reasons) are exempt from the statutory nuisance regime for artificial light, so it is even more important to get the lighting design for these premises right at the outset. Excessive groupings of light that are bright and confusing, commonly found in over-lit cities and inhabited areas. Artificial lighting needs to be considered when a development may increase levels of lighting, or would be sensitive to prevailing levels of artificial lighting. This leads to sky glow.
