Abstract
THIS booklet contains, in a revised and condensed form, much of the information conveyed in the author's well-known larger volume; some additional practical hints are also included. The initial chapter deals with laws and definitions. The effect of light on vision and the origin of glare are then briefly treated. Next Mr. Trotter passes on to a discussion of the chief sources of light, illustrating the distribution of light in each case and pointing out the fundamental principles involved in effective shading. Finally there are chapters on photometry and the planning of lighting installations. The diagrams are invariably clear and informative, and the explanations are lucid. The author has made good use of the space available, and his work will form a useful introduction to illuminating engineering.
