Webinar Schedule

IES Lighting Measurements (LM) 83-23, Approved Method: IES Spatial Daylight Autonomy (sDA) and Annual Sunlight Exposure (ASE) recently underwent significant revisions and ANSI certification. LM-83-23 describes the IES approved method for computing annualized climate-based metrics for daylight sufficiency (sDA) and for excessive sunlight exposure in buildings (ASE). It provides a common reference standard for daylighting performance across building typologies and climate regions. Learn from Daylighting Metrics Committee members about important changes made in the 2023 version and their rationale, along with their implications for daylighting design and analysis. Perspectives and discussion regarding the application of LM-83-23 and an outlook toward the adoption of updated methods in software tools will be included.


Join us for a panel focusing on some of the research being done to improve safety on the road and in the field.  The projects being showcased include adaptive roadway lighting, updates to the FHWA report on mid-block cross-walks, and an assessment of LED exit signs.



LED drivers matter. Their quality, capability and intelligence drive the results of your lighting design and empower lighting controls on your project. This course will provide an in-depth review of the driver performance specifications to deliver quality of light, dimming, flicker-safe capabilities and lighting controls including luminaire-level lighting controls.
