Quality lighting can reduce the demand for electricity. If a business closes, they don't need all their lighting all night. Sports lighting should always be turned off when the events are over. New service stations, convenience stores, and some shopping malls are installing outdoor lighting that is much brighter than levels recommended by national and international lighting organizations. Such lighting can compromise safety rather than help, and it wastes energy.
Examples are low level holiday lighting, quality monument lighting, and such.
Time controls should still be used. Outdoor lighting is somewhat different than other zoning issues. It is good to involve as many elements of the community as possible, at all stages. It covers in much detail all the above issues and more.
