ElumTools computes PPFD for horticulture
ElumTools supports a separate and specific mode for horticultural lighting calculations. When the software is set in Horticulture Mode, luminaires can be assigned output in terms of PPF (Photosynthetic Photon Flux in µmol/s, typically provided by the luminaire manufacturer), or by PPF Factor (µmol/s/kilolumen) which can be computed from the spectral power distribution of the light source. All point-by-point calculations will then be expressed in terms of PPFD (Photosynthetic Photon Flux Density, µmol/(s.m2)). Rendered results are shown in pseudocolor (below).
