    About this Course

    The IES offers Educational Webinars throughout the year, purposefully spanning a broad range of topics and speaker expertise. Metrics in Motion: Connected Lighting was a live webinar, now available as an archived webinar and CEU course.

    Description: The combination of high-efficiency LED technology with seamless control and new features enabled by network connectivity presents a compelling vision for the future of lighting. Much work remains to translate that vision into successful installations, value-added functionality, and proven benefits, including energy efficiency. PNNL researchers are engaged in multiple studies designed to understand and quantify the performance of emerging connected lighting systems. In particular, the ability to measure energy performance at the device and system level is an important focus. This webinar will address some of the questions being pursued in this area, such as how to evaluate the accuracy of energy and electrical data that can be reported by connected lighting systems, and how and where to measure energy use in systems that are capable of essentially continuous change, tuning, and adaptation.

    Learning Objectives:

    By the end of this course learners will be able to...

    1. Describe Connected Lighting and the system components (network devices, light sources, sensors, etc.) within it.
    2. Identify the benefits of energy monitoring and electrical data within a space, and how to interpret that data.   
    3. Explore lighting design criteria and the potential impact of Connected Lighting. 
    4. Consider traditional lighting energy metrics, and the influence Connected Lighting can have on the future of these metrics.

    About this Course

    The IES offers Educational Webinars throughout the year, purposefully spanning a broad range of topics and speaker expertise. Metrics in Motion: Color Metrics was a live webinar, now available as an archived webinar and CEU course.

    Description: After decades of debate and living with limitation, new color metrics for both color rendition and chromaticity have been standardized by the IES and/or CIE. While science has advanced, the practice has been slower to evolve. This webinar will look at recent developments and how they might change lighting practice over the next 10 years. It will demonstrate how all constituents in the lighting community can benefit from using metrics that fit the capabilities of today’s lighting technologies. Manufacturers can more effectively evaluate performance tradeoffs and communicate product performance, allowing differentiation with novel products; specifiers can reduce uncertainty and avoid unsightly consequences, and researchers can use improved methods to investigate fundamental lighting science challenges.

    Learning Objectives:

    By the end of this course learners will be able to...

    1. Understand the history of chromaticity (color of light) measurement and utilize descriptors of it.   
    2. Explore concepts of color rendition including metamerism and chromatic adaptation. 
    3. Understand the basics of TM-30, and new supplemental information including Annex E. 
    4. Learn recommendations and limitations of color criteria in specification.

    The IES offers Educational Webinars throughout the year, purposefully spanning a broad range of topics and speaker expertise. Metrics in Motion: Flicker & Glare was a live webinar, now available as an archived webinar and CEU course.

    Description: Flicker and glare are visual phenomena that have several things in common: both can range from mildly annoying to seriously disabling, both can be made worse by poorly designed LED lighting and better by good LED lighting, and both are the subject of research by PNNL that is helping to further industry-standard metrics, methods of measurement, and recommended practice. This webinar will provide an up-to-date evaluation of progress in addressing these critical lighting quality factors, their implications for energy-efficient LED lighting, and where additional research is needed. 

    Learning Objectives:

    By the end of this course learners will be able to...

    1. Understand why LEDs (as wonderful as they are) have made the issues of glare and flicker more tricky, compared to conventional lighting technologies.  
    2. Learn some of the limitations and a proposed improvement to the UGR metric.  
    3. Acknowledge that flicker is an issue of the driver electronics and dimming systems, and compare several flicker metrics.  
    4. Learn some tips and tricks for identifying flicker from light sources.
