Exterior Lighting

Check that exterior lights are not on during daylight hours, motion sensors are working properly, and daylight sensors, controls, or time clocks are adjusted as necessary throughout the year as daylight hours change. Select energy-efficient and long-life bulbs (as well as low-mercury options for any fluorescent or metal halide bulbs) for bulb replacement. To minimize glare and light pollution of the night sky, make sure that exterior light fixtures are pointed down and are not emitting more light than needed for safety and security purposes. Extremely bright lights can create glare and shadows that reduce visibility and compromise security. If new fixtures are added, select full cutoff or downlit luminaires.
