WebMar 17, 2024 · λ = wavelength in meters. Summing over the range of 400-700 nm yields the photosynthetic photon flux (PPF) per lumen for the given light source: Approximately 8.359 * 10 -3 * Σ (400-700) [λ Φ (λ) Δλ] Given an illuminance value (lux or footcandles), we can similarly calculate the photosynthetic photon flux density (PPFD) in micromoles per ... WebAs light intensity (PPFD) increases, so does the rate of photosynthesis, until a saturation point is reached. ... However, light saturation normally occurs (especially in sun plants) when some other factor (normally CO 2) is limited (Figure 3). Another important consideration regarding light intensity is known as the light compensation point ...
