LITELINE: Understanding Light Quality Through Photometric Reports
What is quality? This session explores the quality of light in the context of lighting fixture design and application. You will learn what defines quality of light by understanding both how light is directed in a space and the spectrum and color characteristics of the light that is emitted. We will unpack concepts such as illuminance, beam angles, CCT, SPD, and TM-30 using real photometric reports to show how these measurements describe what we see. By the end, you will be able to read photometric data and choose fixtures that deliver the experience you want in a space. Learning Objectives: 1. Understand what quality means in the context of lighting fixtures. 2. Understand buzzwords like CCT, center beam candela power, black body curve, SPD, TM-30, and DUV. 3. How to use manufacturers’ published data to support the evaluation of quality light. 4. Use photometric information to select fixtures that create the desired experience in a space and to hold the spec.

…Most outdoor lighting looks acceptable. Very little of it looks correct. The difference is measurable. This session explores how light quality, optics, and documentation work together to create better, more intentional outdoor lighting. Attendees will learn how to interpret TM-30 reports beyond traditional CRI, understand how LED optics and beam control affect real-world performance, and document systems in a way that preserves design intent and supports long-term serviceability. The goal is to show that “perfect light” isn’t simply a matter of taste, it can be specified, measured, documented, and reproduced. Key Takeaways - Interpret TM-30 reports, including Rf, Rg, and color vector graphics, to evaluate real-world color rendition. - Evaluate LED optics and beam control to match photometric performance to the application. - Create fixture schedules and as-built documentation that preserve design intent and support long-term serviceability.
