Security lighting. Lighted areas deter unauthorized conduct, and are easier to patrol. How much lighting and what kind of lighting are appropriate depend on several variables. The size of the object to be illuminated. Larger objects require less light, and larger objects reflect more light. The color of the object to be illuminated. Light colors reflect more light than dark colors. The texture of the object to be illuminated. Smooth-surfaced objects reflect more light than coarse-textured objects. The number of objects to be illuminated. More light is required if there are many objects to be illuminated. Security lighting may be continuous, specific, or selected. Continuous lighting is when a series of overlapping floodlights illuminate an entire area.Specific lighting is when a floodlight illuminates a particular spot, as for example a floodlight above a door. Controlled lighting is used when “full” illumination is neither necessary nor desirable.
