Which of the following characteristics of protective lighting is incorrect?

The characteristic that protective lighting should only be used as a psychological deterrent is misleading. While one of the functions of protective lighting is indeed to serve as a psychological deterrent, its primary purpose extends far beyond this aspect. Protective lighting is designed to enhance visibility and safety in an area, making it harder for unauthorized individuals to conceal themselves.

By illuminating spaces, protective lighting effectively reduces the likelihood of crime by increasing the perceived risk for potential offenders who might otherwise exploit darkness for concealment. Effective protective lighting can also enhance surveillance capabilities, making it easier to detect intrusions or suspicious behavior. Therefore, regarding its role, protective lighting is not limited to just serving as a psychological tool; it plays a crucial role in actual security measures by improving overall safety and aiding in deterrence through increased visibility.
