This informative discussion will discuss the principles of LED technology and how they came to be. Fast forward to today and the state of LEDs has greatly improved in performance and quality. As most light fixtures are embracing LED technology what does the future look like? What is the next standard for color quality? When will efficacy be “good enough”? How will light fixtures change to keep pace with new LED technology? These questions and more will be addressed in IESLA’s inaugural Techfast series.
