Key Features of LUX to PPFD & PPFD to LUX Calculator:

A PPFD calculator is an essential tool for indoor growers and horticulturists who need to measure the intensity of light their plants receive. PPFD, or Photosynthetic Photon Flux Density, is a metric that quantifies the amount of light usable for photosynthesis, measured in micromoles per square meter per second (µmol/m²/s). By using a PPFD calculator, growers can determine the optimal light levels for different plant species, ensuring healthy growth and maximum yield. For German-speaking users, a PPFD rechner serves the same purpose, offering a convenient way to calculate light intensity in their preferred language. Additionally, understanding the relationship between PPFD in lux is crucial, as lux measures visible light to the human eye, while PPFD focuses on the light spectrum plants use. Tools like an umol to PPFD calculator simplify the conversion process, making it easier to interpret lighting data across different units.

When comparing PPFD vs lux, it’s important to recognize that these metrics serve different purposes. While lux measures the brightness of light as perceived by humans, PPFD quantifies the number of photons within the photosynthetically active radiation (PAR) range that plants can absorb. For growers transitioning from traditional lighting systems, understanding this distinction is vital. A PPFD calculator or umol to PPFD calculator can bridge this gap by converting lux values into PPFD, providing a clearer picture of how effective a light source is for plant growth.

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

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).)
