A strong focus on transparency and educating our partners on the correct lighting specifications is just part of the process here at Veteran LED. It’s very easy to get confused with all of the different information manufacturers share in their marketing materials and on specification sheets. The acronym soup of PE, PAR, PPF, PPFD, CU can seem daunting. Lets break it down as simple as we can…
When it comes to horticulture lighting, understanding the difference between PAR, PPF, and PPFD can really alleviate some misunderstandings!
PAR stands for Photosynthetic Active Radiation. PAR is not a measurement, but rather the type of light needed (wavelength between 400-700nm), that a plant needs to support photosynthesis. How much PAR a light fixture produces is measured in Photosythetic Photon Flux. How much PAR is available to the plants is measured in Photosynthetic Photon Flux Density. The efficiency of the fixture is Photon Efficiency.
All factors discussed need to be considered when choosing the right horticulture lighting system. Call us today at 804-562-8606.
