PPF (µmol m-2 s-1) to LUX
Sun54
Fluorescent white lamp74
HPS (sodium)82
Lampe High Pressure Metal Halide 71

LUX to PPF (µmol m-2 s-1)
Sun0.0185
Fluorescent white lamp0.0135
HPS (sodium)0.0122
Lampe High Pressure Metal Halide 0.0141


Multiply PPF by the conversion factor to obtain Lux. For example in the sunlight:
2000 µmol m-2 s-1 = 2000*54 = 108.000 Lux
