Photon efficacy
Webso the luminous efficacy metric is not appropriate for plant applications. The appropriate metric for plant lighting is photosynthetic photon efficacy (PPE). This is the PAR photon output (unit of micromoles per second, or µmol·s–1) divided by the input power (watts, or W) to produce that light. Thus, the unit WebAn Update on Lighting Efficacy. In plant lighting, the efficacy (or more precisely, the photosynthetic photon efficacy) of a fixture quantifies how effectively a fixture converts …
