Annotation
Equally applicable to both residential and commercial audiences, this film describes lighting as one of the most cost-effective tools for crime prevention and gives actual examples of both good and bad lighting.
Abstract
The film discusses how reflective colors and materials can increase the apparent amount of light, why the intensity of light is important, the positioning of light for safety and crime prevention, and the economics of the various types of lighting. The film also compares different sources of light and how they affect color perception. This is especially important for officers as often the light color will affect a witness' description of a suspect. Side-by-side comparisons show how colors change under different types of light. The different types of lighting discussed include high-pressure sodium, low-pressure sodium, metal halide, tungsten, warm-white flourescent, cool-white flourescent, and sunlight. The film also warns about improper disposal methods of the low pressure sodium lamp fixture, using National Safety Sheriff Joe Higgins to demonstrate this danger. The script was reviewed and the lighting comparisons were filmed under the auspices of the California Crime Prevention Officers Association membership. (Author abstract modified)
