National IES Events:

June 13th IES Detroit Applying TM-30-15 for Evaluating Light Source Color Rendition

Buy Tickets at this Eventbrite Link

Please join the IES Detroit Section for our June Meeting! This meeting will feature Dr. Kevin Houser speaking on IES TM-30-15.


IES TM-30-15 is a relatively new method for evaluating light source color rendition. This presentation will explain the novel features of the system. Also discussed will be best practices in specifying color rendition, remaining limitations, and considerations for the lighting industry as we transition from existing measures to more complete and accurate evaluations of light source color rendition. Visual examples for numerous spectra will be presented using a 7-channel spectrally tunable light source. The audience will become knowledgeable in interpreting the numerical and graphical results from TM-30-15.


Learning Objectives:

After attending this program, participants will be able to:


1. Comprehend the conceptual framework for TM-30-15s color rendition evaluation system

2. Describe the components of TM-30-15s color rendition evaluation system and how they can be interpreted to aid design and specification

3. Recognize the strengths and limitations of this system, and more generally recognize the limitations of all measures for color rendition


About the Presenter:

Dr. Houser is a Lighting/Electrical faculty member in the Architectural Engineering Department at Penn State University. His research focuses on applied uses of optical radiation, including fundamental inquiries into human perceptual and biological responses, and the application of this knowledge to the spectral design of light sources.


Dr. Houser has created prototype light sources based on models from vision science. He has quantitatively demonstrated improved color perceptions and increased brightness perceptions in comparison to conventional light sources. He is now carrying out related work with GE Lighting that is focused on the underlying relationships between spectrum, brightness perception, and color perceptions, especially as these psychophysical dimensions relate to solid state lighting (e.g., light emitting diodes). His research in the spectral design of light sources is rooted in energy efficiency, and has been supported by the US Department of Energy and the California Energy Commission. He has also expanded the application of spectral tuning to human photo biological health. He is part of a team that includes medical professionals and researchers at Penn State Hershey. The team is employing optical radiation to improve sleep quality, cognition, mood states, and immunological responses in elders.


He has been on the Board of Directors for the International Association of Lighting Designers, the Illuminating Engineering Society of North America, and the Nuckolls Fund for Lighting Education. He is a current board member of Lux Pacifica, and is editor-in-chief of LEUKOS, the journal of the Illuminating Engineering Society.
