Upcoming Webinar: Highlighting Consensus-Driven Development of an Important New Standard
Balancing Competing Interests in Lighting Quality and Energy Use

If you’ve bought a light bulb recently, you’ve likely encountered an overwhelming number of choices. This stems from two major trends: the growing demand for energy-efficient products and advancements in light emitting diodes (LEDs), which create more light per watt and offer a wider range of color-related qualities.
As LEDs started replacing incandescent bulbs in the 2000s, it became clear that a new evaluation standard was required to balance the competing goals of lighting quality and energy efficiency. The Illuminating Engineering Society‘s Color Committee—comprising experts in human perception, lighting research, interior design, energy engineering, and manufacturing—took on the challenge. By synthesizing research findings and existing methodologies, they developed TM-30, a standardized system for specifying and rating the color rendition of light sources.
In this webinar, Dr. Michael Royer (Pacific Northwest National Laboratory) and Dr. Kevin Houser (Oregon State University) will discuss the committee’s challenges, the collaborative approaches that led to both the creation and widespread adoption of TM-30, and key lessons for other HIBAR projects—including the benefits of aligning a project’s leadership structure with its goals.
