Photon efficacy
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. WebJan 1, 2024 · The final photon efficacy of a light-emitting diode (LED) luminaire is determined by the inherent efficiency and photon wavelength of the LED package(s), …

The values range WebJun 6, 2024 · PPF: Photosynthesis Photon Flux (µmol/s) PPE Understanding the Photosynthesis Photon Efficacy (PPE) is important for growers while taking buying decision of grow lights.
WebThe 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 becomes μmol·s–¹·W–¹, and because one watt (W) equals one joule per second (J·s–¹), the ... WebPhotosynthetic Photon Efficacy (PPE) PPE measures a light fixture’s efficiency for converting electrical energy into PAR light. This is expressed as micromoles per Joule (μmol·J-1). PPE is an important measure for comparing the efficiency of different manufacturers’ fixtures.
