About this Course
The IES offers Educational Webinars throughout the year, purposefully spanning a broad range of topics and speaker expertise.
Description: With ANSI/IES LM-85-23 Approved Method: Optical and Electrical Measurements of LED Sources, optical measurements are now tied to junction temperature, eliminating a significant error source. LED measurements will now be more consistent and repeatable. But how is LM-85-23 really applied when considering LED product design? What are the short-term and long-term benefits?
