WebLumens are a measurement of the amount of light that’s visible to the human eye. Lux is the measurement of the intensity of lumens (exe. 1 lux equals 1 lumen per square meter). These measurements shouldn’t be used in horticultural applications since they don’t measure the light that plants use for photosynthesis. WebLumen: A standardized unit of measurement of the total amount of light emitted. Put simply, the more lumens, the brighter the light. Lux: A standardized unit of measurement of light level intensity in a specific area. Watt: Contrary to lumen and lux, watt refers to the energy consumed by the product, not the light output coming from product itself.

WebIt was originally defined as the energy in one mole of photons ( 6.022 × 1023 photons). [1] [2] Because energy is inversely proportional to wavelength, the unit is frequency dependent. This unit is not part of the International System of Units (SI) and is redundant with the joule. WebTherefore, we need to use quantum units. Since the number of photons is so large, we measure them in moles (mol) of photons, and 1 mol = 6.022 × 1023. One micromole (μmol) equals 1 × 10-6 mol so therefore, 1 μmol = 6.022 × 1017. ...
