Discusses research undertaken to determine recommended levels of lighting for effective seeing. Factors considered include age, veiling reflections, brightness differences, glare, and pleasantness. Also points out some common lighting practices that are wasteful and inefficient and suggests alternatives. (DN)

Imaging of artwork is an important aspect of art conservation, technical art history, and art authentication. Many forms of near-infrared (NIR) imaging are used by conservators, archaeologists, forensic scientists, and technical art historians to examine the underdrawings of paintings, to detect damages and restorations, to enhance faded or…

A fundamental change in attitudes toward lighting can produce considerable reductions in the amount of electricity required to operate educational and other facilities. (Author)

The same form of lighting will not be effective in all areas of a school facility. Factors to be considered include physical and psychological effects, visual requirements, and cost. A chart illustrates type of lamp, output/energy ratio, light "quality," and applications. (MLF)

The primary function of this book is to treat the topic of lighting design in such a manner as to bridge the gap between architects and illuminating engineers. The work is divided into three parts: Part I, Principles of Design, offers information and analysis of how natural and artificial lighting affects building design, how illumination levels…

Using Keene "Director" fixtures, a Rotterdam, New York, school will save over $16,000 annually and have improved classroom light. These fixtures will pay for themselves in 3-4 years, halving the wattage used per square foot; they direct 40 percent of their light upward to provide uniform, glare-free lighting. (MCG)

Merrimack College in North Andover (Massachusetts) has reduced the cost of lighting its physical education center by over 70 percent; the new lighting system, which uses metal halide lamps, has also doubled the illumination in the building, attracting revenue-producing activities. (MCG)
