Conversion – Lux to PPFD :

NOTE: The conversion from Lux to PPFD (µmol m-2 s-1) varies under different light sources. For a complete discussion please see the reference listed below.

Lux to PPFD (µmol m-2 s-1)

Light Source	Calibration Factor
Sunlight	0.0185
LED ( 6000-6500k)
Cool White Fluorescent Lamps	0.0135
Mogul Base High Pressure Sodium Lamps	0.0122
Dual-Ended High Pressure Sodium (DEHPS): ePapillion 1000 W	0.0130
Metal Halide	0.0141
Ceramic Metal Halide (CMH942): standard 4200 K color temperature	0.0154
Ceramic Metal Halide (CMH930-Agro): 3100 K color temperature, spectrum shifted to red wavelengths	0.0170

Multiply the Lux by the conversion factor to get PPFD. For example, full sunlight is 108,000 Lux or 2000 µmol m-2 s-1 (108,000 ∗ 0.0185).
PPFD (µmol m-2 s-1) to Lux

Light Source	Conversion Factor
Sunlight	54
LED
Cool White Fluorescent Lamps	74
Mogul Base High Pressure Sodium Lamps	82
Dual-Ended High Pressure Sodium (DEHPS): ePapillion 1000 W	77
Metal Halide	71
Ceramic Metal Halide (CMH942): standard 4200 K color temperature	65
Ceramic Metal Halide (CMH930-Agro): 3100 K color temperature, spectrum shifted to red wavelengths	59

(Multiply the PPFD by the conversion factor to get Lux. For example, full sunlight is 2000 µmol m-2 s-1 or 108,000 Lux (2000 ∗ 54).)
