Some LED manufacturers tout their high photosynthetically active radiation (PAR) values. Their
fixtures produce more PAR, they say, and therefore are superior.
Not so. A lighting manufacturer should tell you that you need to ask about the photosynthetic photon flux density (PPFD).
PAR is defined by the International Commission on Illumination as the total photon exposure in the 400nm to 700nm waveband range of radiation that is absorbed by photosynthetic pigments.
PAR is not a quantitative measure; it’s merely a description of the light that plants need for photosynthesis. PPFD, on the other hand, is a quantifiable measure of the total number of photons in the photosynthetically active range of wavelengths that fall on a square meter of a given surface (say, a plant canopy) every second. In other words, PPFD is a measured metric whereas PAR is merely a descriptive term for a range of wavelengths.
