The formula to calculate Lux from PPFD (\(\mu mol m^{-2} s^{-1}\)) is:
\[ Lux = PPFD \times Conversion\ Factor \]
Where:
PPFD (Photosynthetic Photon Flux Density) is a measure of the number of photons in the photosynthetically active radiation (PAR) range that are incident on a surface every second.
Lux is a measure of illuminance, the total amount of visible light illuminating a point on a surface.
Let's assume the following values:
Using the formula:
\[ Lux = 100 \times 54 \]
Evaluating:
\[ Lux = 5400 \]
The Lux is 5400.
