PPF, PPE, PPFD, DLI and Power,are the main parameters we when we talk about LED grow lights.
Abbreviation | Full Name | Unit |
PPF | Photosynthetic Photon Flux | umol/s |
PPE | Photosynthetic Photon Efficiency | umol/j |
PPFD | Photosynthetic Photon Flux Density | umol/(s*m²) |
DLI | Daily Light Integral | mol/(m²*d) |
Power | w |
