In your seek for led grow lights, you’ll have encountered the acronym “PPFD.” an abbreviation for Photosynthetic Photon Flux Density, PPFD may be a live of the amount of photons within the 400-700nm range of the light spectrum (Photosynthetic Active Radiation or PAR ) that fall on a square measure of target per second. Why does one ought to grasp this? Any light manufacturer will brag concerning the large quantity of sunshine a fixture produces. however if that light isn’t reaching to the target (i.e., the plant canopy), all that light is wasted. You flip the activate your light and far of the generated light can hit its supposed target. However, a share of the sunshine photons ne’er build it to the target because of optical losses. Lost light is lost money, as a result of you’re burning energy to send light photons off in directions you don’t wish them to go.
IES led grow lights area unit engineered with breakthrough LED optics that extract and direct photons at the die level, delivering a lot of usable light to the supposed target, with significantly less light spillage than the lights of different makers. We’ve created an led package that emits light in a very uniform, extremely precise beam directly from the supply.
Many lamp makers still specify the output of their fixtures (flux) in lumens, although this simply specifies however humans understand the intensity of the sunshine. Plants “see” a far completely different spectrum of sunshinethan do humans, therefore to accurately assess grow light LEDs, one should perceive the quantity of plant-usable light (Photosynthetic Photon Flux or PPF) your fixture emits, the gap from the sunshine to your plants, and your growing space.
To calculate the amount of usable light that is reaching your plant canopy you must first know the LED fixture’s PPF. Then you can send us an inquiry, offering the target area length, width,distance between lamp and the plant,then we can calculate and offer advices about how much light your plants are actually getting from your fixture. Different plant species have different PPFD requirements, so compare your results to the PPFD your crop needs. Before you buy a light, learn about its PPF output. You want an LED grow light that uses the least amount of energy to generate the most amount of light that gets to your plant canopy and makes your plants grow. IES’s patented LED optics will not disappoint.
