Every discipline has its own special terminology and lighting is no exception. Fortunately, in lighting, there are only five basic metrics that need to be learned for measuring light. Unfortunately, they have similar names and unusual units, and may be a challenge for a beginner in lighting to comprehend and understand. In a clear, straightforward manner, TM-1-12 shows the reader how to perform the five basic calculations: luminous flux, luminous intensity, illuminance, luminance, and luminance exitance.
The Five Lighting Metrics (TM-1-12) is available in print or as a PDF download from the IES at www.ies.org/store. List price: $20.00; IES Member Price: $14.00. ISBN: 978-87995-264-8. Softcover, 8 ½ X 11 format, 7 pages.
IES is the oldest and largest educational and scientific society in North America devoted to lighting. Since 1906, the IES has sought to improve the lighted environment by bringing together those with lighting knowledge and by translating that knowledge into actions that benefit the public. A broad variety of programs, including publications, conferences and seminars, have been established to accomplish this mission. IES publishes and distributes the finest lighting literature authored by committees with the most experienced minds in industry and academia today.
