The IESNA Lighting Handbook, also known as the "Bible of Ligting" is an helpful reference tool for industry professionals. Included in one comprehensive volume is everything one needs to know about lighting – explanations of concepts, techniques, applications, procedures and systems, as well as detailed definitions, tasks, charts and diagrams. Full color illustrations exemplify important concepts and expert contributions ensure technical accuracy.

The 9th edition includes the Lighting Design Guide (Chapter 10) which replaces the former illuminance recommendation table and changes the way lighting issues for the next millenium are considered.

The following is a sampling of some revisions that are included in the Lighting Handbook:

Chapter 15: Theater, Television and Photographic Lighting – new information on lamps, dimming controls and emergency lighting.

Chapter 19: Industrial Lighting – reflects a change in philosophy. Previous editions detailed lighting practices for specific industries. The new approach allows the reader to find recommendations on lighting for several industrial tasks. There is also added emphasis on vertical illuminance.

Chapter 20: Sports and Recreational Facility Lighting – includes new calculation procedures for the Modified Lumen Method and Point Method as well as updated illuminance recommendations.

Chapter 21: Exterior Lighting – completely rewritten to provide guidance on limiting light trespass and is compatible with the growing trends in urban legislation.

Chapter 22: Roadway Lighting – material on care of trees within the line of roadway luminaires is completely rewritten.
