Welcome to the Horticultural Lighting + Tech newsletter by LEDs Magazine for July 10, 2023. Sadly, the LED and solid-state lighting community has lost a dedicated horticultural science and technology advocate in the passing of our longtime contact Ian Ashdown. Ian’s last contributed article for LEDs was a comparison of the PAR and ePAR (extended photosynthetically active radiation) metrics, their ability to serve in characterizing photosynthetic photon efficacy, and what other plant responses are impacted by light, where standards may be lacking. Ian’s depth in horticultural science was also reflected in his work with the IES RP-45-21 committee and his development of software dedicated to greenhouse lighting design, spun out in the company HelioSol Software Solutions.
