A Proposed Two-Parameter Approach To Recommended Lighting Levels

Tuesday September 15, 2026 12:00pm - 1:00pm CDT

Education Station @ ArchLIGHT Summit Show Floor

Illuminance, measured in foot-candles or lux, has long been the metric used to recommend lighting levels for specific applications. From Waldram’s Designed Appearance Method to Cuttle’s Mean Room Surface Exitance (MRSP) approach, there has been considerable interest over the years in moving away from illuminance as a basis for lighting design in favor of luminance and exitance.

This session will provide participants with a perspective of illuminance recommendations over time, along with a bit of history of some of the approaches to design criteria beyond illuminance. But it then takes the perspective that two metrics are likely necessary to adequately address end users’ perception of the adequacy of illumination in various applications.

This paper explores the combination of illuminance and MRSP in a systematic way through a series of analyses of representative applications to determine the efficacy of these metrics for lighting design recommendations and practice. Both illuminance and MRSE are determined for a series of scenarios using multiple room sizes, reflectances, and lighting systems for several application types (e.g., office, classroom, conference room, etc.). Proposed recommendations for these two parameters are then suggested for a variety of applications.

Why DALI Makes Sense for Outdoor Lighting Control

Tuesday September 15, 2026 1:00pm - 2:00pm CDT

Education Station @ ArchLIGHT Summit Show Floor

The scale of outdoor lighting offers bigger challenges for controls selection and operation. Installation costs, encompassing wiring and labor, can be prohibitive. Post-installation adjustments can require burdensome additional efforts.
Wouldn’t it be great if there was some control solution that bypassed these challenges yet offered superior control capabilities and ease of installation? Enter DALI! By using this open standard, project professionals can unlock a range of benefits including:
• Multi-vendor compatibility for luminaires, drivers, sensors, and controllers without being locked in to a single vendor’s solution
• Design flexibility and future proofing with individual addressability, ease of grouping or regrouping
• Flexible design and future-proofing
• Reduced operating costs with predictive maintenance reports on failing components
• Centralized remote monitoring with fault detection and integration into other building management systems

This session delves into the use of DALI standards for designing outdoor control projects like parking garages and other site lighting applications. The panelists explore common misconceptions, best design and installation practices, and lessons learned from real-world projects.

LP-30: A Phase-by-Phase Approach to TM-30

Tuesday September 15, 2026 1:00pm - 2:30pm CDT

Hudson Valley Lighting Group - TM 3902

This introduces ANSI/IES LP-30, which presents a phase-by-phase implementation of TM-30, from schematic design to construction documentation. TM-30 is a method for evaluating color developed by the Illuminating Engineering Society (IES) that uses design intents of Preference, Vividness and Fidelity to assess and improve lighting quality. By understanding the TM-30 information gathered at each stage of design, designers can create lighting solutions with a broader range of color rendering goals that meet specific requirements and enhance overall environments. Integrating TM-30 into design processes and specification documents ensures that the desired lighting characteristics are achieved and maintained throughout the project.

“Selectable” Lighting: One Size May Not Fit All

Tuesday September 15, 2026 4:00pm - 5:00pm CDT

Varaluz/Ciana Showroom - TM 4507

In recent years there has been a proliferation of LED products with combined attributes of selectable wattage, CCT, beam angles, etc. A primary benefit of integrating these features is a reduction in the SKU or part numbers for manufacturers and suppliers, but is it beneficial to the design community? In this panel discussion which brings perspectives from the lighting design and lighting manufacturer’s perspectives, we compare and contrast selectable lighting attributes in luminaires and consider which applications may benefit and where the use of a “one size fits most” lighting approach should be avoided.
