PAR as a measurement of light intensity for plants is vastly better than lumens, but choosing a light based on a PAR number or PAR per watt is not smart for a lot of reasons. Put simply, it is possible to have a light with a lower PAR number that will grow plants better than a light with a higher PAR number.

So What Is a PAR? Essentially a PAR is the amount of light that is actually available to be used during the photosynthesis process. There may be more light emitted from a particular source, but your plants don’t make use of all of it – some of it has no real effect on the photosynthesis process. It might be best to explain this with an example.

Jul 15, 2020 PAR (Photosynthetic Available Radiation) is the amount of light or intensity that is in the proper spectrum for corals to use. PAR Meters can be handy tools to measure light intensity at discrete points, but how meaning actual photosynthetic response is limited to canopy level foliage. PAR meters actually measure light intensity (not actual photon counts), it must have a degree of intensity that is emitted outside of the defined PAR region of. Products 1 - 42 of 76 These lighting fixtures typically use the reflective quality of the enclosure to enhance and shape the light.

PAR, PPF, PPFD. and DLI are precise and consistent terms and measurements used by scientists, algae researchers, horticulturists and labs around the world --- but they can be difficult to memorize and grasp. So here’s a way to make it easier: Think of light as rain and the light fixture as a cloud.
