Fluence scientists study photosynthetic photon flux density (PPFD) and spectra impact on full-cycle plant physiology and chemical composition. In addition to primary research, Fluence collaborates with global research institutions – including Princeton University, the United States Department of Agriculture, University of Florida and Bayer CropScience – across a diverse range of studies from Geosciences to Food and Agricultural Sciences.


Research is conducted using scientific tools, including the latest gas exchange analysis equipment, PAR meters and integrating spheres from Qubit Systems, LI-COR and U.S. Dept. of Energy accredited laboratories to calculate and measure:


  • Total photon flux
  • Intensity distribution
  • Photosynthetic rates
  • Transpiration rates
  • Water use efficiency
  • Leaf, root and whole plant physiology

Product Development


All Fluence lighting systems and spectra are designed and built in Austin, TX using an assembly process combining robotics, automation and engineering craftsmanship.


Spectra options are formulated to elicit unique plant growth characteristics targeting specific plant responses, whether for commercial cultivation or research. Engineered for maximum energy efficiency and cost savings, each spectrum is developed with pre-focused LED radiation patterns ranging from 80° – 140° Full Width Half Max (FWHM) from the top semiconductor manufacturers, including Osram and Samsung.
