The formula to calculate the PPFD (\(\mu mol m^{-2} s^{-1}\)) from Lux is:

\[ PPFD = Lux \times Conversion\ Factor \]

Where:

• \(PPFD\) is the Photosynthetic Photon Flux Density.
• \(Lux\) is the illuminance in lux.
• Conversion Factor depends on the type of light source.

The formula to calculate the temperature increase (\(\Delta T\)) from PPFD is:

\[ \Delta T = \frac{PPFD}{13} \times 0.5 \]
