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 WebWhat is photosynthetic photon efficacy? PPE (photosynthetic photon efficacy) is the PAR photon output of a light source (measured in micromoles per second or mol/s) divided by the input power (W) to produce that light. PPE (measured in mol/J) will provide growers with insights into how competent the light is at converting watts into photons.
