Convert LUX to PPFD Converting LUX (Lumen/m²) to PPFD Photosynthetic Photon Flux Density. The Conversion-factor is depending on the light spectrum. Note: a higher value does not indicate a better or more efficient light source. LUX / light-meter are much less expensive than a quantum spectrometer to measure PPFD. Also, every state of the art…
Plant VS Human lighting terminology Important lighting termininology, terms and units Light for Plants Light for Humans PAR Photosynthetic Active Radiation Radation between 400 and 700 nm (nanometer) of the solar spectrum can be used by phototropic organism, like plants to drive photosynthesis. This radation is called photosynthetic active Radiation or PAR. Visible Light Radation…
Daily Light Integral DLI: Daily Light Integral mol/m²d Daily light integral (DLI) describes the number of photosynthetically active photons (individual particles of light in the 400-700 nm range, PAR) that are delivered to a specific area over a 24-hour period. This variable is particularly useful to describe the light environment of plants. Source: Wikipedia – DLI More about…
