Welcome to NEMA Academy!

This learning module surveys available protocols, how they work in a lighting control system, and specification considerations.  Read more

Introduction to Lighting Control provides an overview of the basic functionality of today’s lighting controls, benefits and the basic questions to ask when identifying an appropriate lighting control strategy. Read more

Color tunable light sources provide tremendous flexibility in terms of spectral power distribution, but the resulting range of variation in chromaticity, color rendition, and other characteristics poses a challenge for product characterization and specification. The millions or billions or trillions (or more!) of spectral power distributions that can be created from one luminaire enables designers to meet various design intents and influence the visual appearance of spaces. However, in contrast with characterizing the performance of a fixed-output luminaire, there are no established methods or guidelines for characterizing performance over the tuning range for the variety of SPD-related metrics, which can impede engineering and specification of color tunable products. Using a massive dataset generated with high-performance computers, this webinar will discuss new methods to convey the extent to which color rendition can be varied, and how different factors (number of LED channels, type of LEDs) influence the range of performance.

States, provinces, and cities across North America update their building energy codes and standards to further energy efficiency and conservation as well as construction practices. This presentation will review the most important and recent code changes as it deals with lighting and lighting controls. Most importantly, will review best practice lighting power and control design application for multiple common space types, while avoiding common code mistakes and misunderstandings reducing the confusion or challenges for lighting designers and engineering professionals when designing building lighting power and controls to meet codes.

Shaun Fillion provides an under-the-hood look at radiosity calculations and raytrace renderings. We take look at the methodology used by photometric calculation software to represent the performance of lighting in the built environment, tracking it from the roots of the Lumen Method and Inverse Square Law. Visual representations of illuminance versus luminance are also covered. The seminar also diagnoses and tweaks example models to make the lighting calculations more accurate. Read more

In 2008 the IES published LM-79, “Approved Method: Electrical and Photometric Measurements of Solid-State Lighting Products.” This measurement standard for solid-state lighting products quickly became the world recognized standard for measuring LED lighting products. In 2019 the IES Test Procedures Committee (TPC) completed a comprehensive review and revision of LM-79. The revision was published as ANSI/IES LM-79, “Approved Method: Optical and Electrical Measurements of Solid-State Lighting Products.” The revision includes better guidance on how to make measurement and requirements that help to reduce measurement variations between different testing facilities. Consideration for these changes was based on information collected from NVLAP proficiency testing, independent research, and an effort to help minimize the burden on testing laboratories. Join us for our first educational session on LM-79 since the revision was published, and learn from experts in this topic Cameron Miller and Eric Bretschneider. Read more
