Illuminance is light falling on a surface measured in footcandles. Distributed with an economic and visual plan, it becomes engineered lighting and, therefore, practical illumination.
Solution to a Design Problem
There are two parts to the solution of a design problem. One is to select lummaires which are designed to control the light in an effective and energy efficient manner. The other is to apply them to the project with all the skill and ingenuity the designer can bring to bear from his own knowledge and all the reliable sources at their disposal.
This primer has been developed to give the designer a useful summary of basic lighting principles. It gives important data and practical information on how to apply them. It offers the assistance of the Holophane technical sales force who have Visual® application software at their disposal. The facilities and staff of the Holophane Technical Support Group are also available.
In addition, it prefaces a selection of quality lighting products that use the best design and manufacturing techniques of illumination science and technology available today. Their use assures the ultimate in lighting quality, economy1 light distribution, energy efficiency and glare control.
