WebIn reality, however, obtaining a light source's exact SPD is not an easy task for the average grower - it requires expensive spectrometer equipment. We have therefore developed the calculator below which allows for approximate conversions between lumens and PPF based on some assumptions about the light source's SPD.
Web23 jan. 2024 · How do you calculate total luminous flux? The lumen is derived from the unit of luminous power, the candela (cd). Thus one lumen is the luminous flux emitted within unit solid angle (one steradian) by a small source having a uniform luminous intensity of one candela, so that 1 lm = 1 cd sr, and the total flux in all directions is 4 π lm.
