Learn about the latest developments in photometric testing and evaluation, including new testing requirements for solid-state light sources and systems.
(Dates for the 2014 Photometry Institute to be determined.)
Who should attend?
- Engineers, technicians, and testing personnel from lighting and related companies interested in learning more about photometric, colormetric, and related evaluation of lighting products and prototypes.
- Personnel from testing facilities who want to hone their skills and knowledge about testing requirements for solid-state as well as traditional light sources and lighting systems.
- Managers, engineers, product developers and designers from lighting and related companies interested in setting up photometric testing capabilities to benchmark and evaluate product prototypes in their own facilities.
- Anyone who wants to know more about the rapidly changing requirements for testing and evaluation of solid-state light sources and systems.
What will you learn?
People who attend the two-day, hands-on Photometry Institute will come away with the knowledge and skills needed to establish and conduct photometric testing and evaluation of a wide range of lighting products and systems. At the conclusion of the seminar, participants will:
- Understand photometric and colorimetric terms and concepts used in lighting measurement and product evaluation;
- Understand and be able to conduct industry standard test procedures and requirements included in programs such as ENERGY STAR®, Lighting Facts, and others;
- Understand and be able to operate the various types of equipment used in lighting measurement and photometric evaluation;
- Understand standard photometric laboratory practices and protocols and be able to apply these in their own facilities;
- Understand requirements for testing and measurement of solid-state light sources and systems and be able to accurately evaluate the performance of solid-state lighting products;
- Be able to measure standard photometric quantities including illuminance, luminance, luminous flux, and luminous efficacy;
- Be able to measure and calculate various spectral and colorimetric quantities such as correlated color temperature and color rendering index;
- Understand the equipment needed to create and/or assemble inexpensive photometric capabilities in their own facilities to make accurate measurements of the performance of pre-production prototypes;
- Be able to interpret and apply photometric data in the evaluation of product prototypes and models.
How is the Institute structured?
The Photometry Institute is designed as an intensive, two-day, interactive experience that will allow participants to learn hands-on using the LRC’s extensive, NVLAP (National Voluntary Laboratory Accreditation Program) accredited photometric laboratories and equipment (LRC’s NVLAP lab code: 200480-0). The course will include lectures, equipment demonstrations, and laboratory exercises, guided by the LRC’s expert faculty and staff. The Institute runs from 8:30 AM to 5:00 PM each day and is held at the LRC’s facilities in Troy, New York. Topics covered in the Institute will include:
- Photometry – terminology and definitions, lighting calculations
- Photometric equipment set up and calibration
- Measurement of light – use of photometric equipment including an integrating sphere, goniometer, and spectrometers
- Colorimetry – terminology and definitions, measurements, and calculations
- NVLAP and laboratory practices
- Solid-state lighting testing and measurement including LM 79, LM 80, and LM 82
- Photometry data review, interpretation, and reporting

Who are the instructors?
Instructors for The Photometry Institute will include a number of LRC faculty and staff:
Andrew Bierman, MS, LC — Professor Bierman is a senior research scientist at the LRC and an expert in photometry and radiometry. He is currently conducting research on the non-visual effects of light on health and circadian regulation. Other areas of research include mesopic vision (vision at low light levels), color vision, lighting controls, measurement of lighting efficiency, photosensor technology, and fluorescent lighting systems. Professor Bierman is one of our country's leading experts in photometric measurement and is the head of the LRC’s photometric laboratories.
N. Narendran, PhD — Dr. Narendran is a professor and director of research at the LRC. He is well known throughout the lighting industry for his pioneering research and educational activities in the field of solid-state lighting. Dr. Narendran leads a team of researchers and educators in the area of solid-state lighting at the LRC, and conducts research and educational programs to accelerate the development and market transformation of this promising technology. Dr. Narendran teaches the Physics of Light course within the LRC’s graduate education program, which includes photometry and optics. In addition, he has developed and taught courses in optics, LEDs, and fiber optic lighting. Dr. Narendran has authored or co-authored more than 100 articles in archival journals and proceedings and holds several patents. He is a Fellow of the Illuminating Engineering Society of North America.
Mark S. Rea, PhD — Dr. Rea is the director of the LRC and an expert in human vision, lighting engineering, human factors, photobiology, psychology, and light and health. He is the author of more than one-hundred scientific and technical articles related to vision, lighting engineering, and human factors and was the editor-in-chief of the 8th and 9th editions of the IESNA Lighting Handbook. His current research projects include the development of new metrics to improve the acceptance of energy-efficient lighting technologies, the study of the effects of light on circadian disruption, and research on reducing the market barriers to widespread use of energy-efficient lighting. Dr. Rea has conducted groundbreaking research in the areas of human visual performance, visual efficacy at nighttime light levels, and light and human health. His exceptional research expertise and experience along with his outstanding leadership and management capabilities are a great asset to this course.
Yiting Zhu, PhD — Dr. Zhu is a research scientist at the LRC. She manages the LRC’s technology testing and evaluation program. Her current solid-state lighting research includes optical design, phosphor characterization, LED package and system reliability, photometry and OLEDs. She has several publications in the field of phosphor-converted LED packages and received the 2007 best paper award at the First International Conference on White LEDs and Solid State Lighting. During her doctoral study, she was the recipient of the Link Foundation Energy Fellowship (2007-2009).
