About the PPFD to Lux Calculator
You may find yourself comparing LED grow light specifications, where one light uses lux and the other uses PAR units such as PPFD (umol). How do you compare the two?
It is not possible to convert PPFD to Lux absolutely accurately without providing the light source's spectral power distribution (SPD). In 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 lux and PPFD based on some assumptions about the light source's SPD. To improve the approximations for your particular light source, select the SPD that most closely resembles that of your light source.
