LED lights require new thinking about the way we measure light for use by plants. The definition of the lumen is the total light produced within the range of the human visual response. It tells us nothing about the distribution of that light energy over the spectrum, and most importantly, it doesn't tell us how much is useful for plants. The problem with lumens is especially pronounced when measuring light at the far ends of the human visual response curve. Consider three lamps-red, green and blue-each emitting the same number of watts of optical energy.
The red and blue lamps would have much lower lumen ratings compared to the green lamp, simply because the human visual response is very low at red and blue, and highest at green. Similarly, light meters that measure in "lux" tell us very little about a lamp's plant-growing power. The light sensors in lux meters have their own spectral response curves which may over- or under-measure light at various colors. This is why lux meters usually have different settings for "sunlight, " "fluorescent" and "incandescent" lamps.Again, because lux meters are meant for measuring the amount of light usable by humans, they don't tell us anything about how plants will respond. Plant biologists define light in the 400nm to 700nm spectral region as "photosynthetically available radiation, " or PAR.
The unit for measuring PAR, micro-mols per second (? Mol/s), indicates how many photons in this spectral range fall on the plant each second. Inexpensive PAR meters use sensors that respond over the entire 400-700nm spectrum, and have their own sensitivity curves that require different calibration for sunlight, fluorescent and HID lighting.
All these systems are too broadly responsive to measure an LED's narrow emission spectrum. They make HID light seem brighter by over-measuring yellow-green light, and make LED light seem dimmer by under-measuring red and blue light. To properly measure the amount of energy present for photosynthesis we must use a spectroradiometer. This instrument measures energy in watts at each specific wavelength over a range of wavelengths. A spectroradiometer can provide a direct comparison of each lamp's ability to produce light that plants can use for photosynthesis.
Spectroradiometers are expensive instruments, not usually found outside laboratories. A more common instrument called a spectrometer can show relative light output over a spectral range, but does not measure energy in watts. Manufacturers should publish spectroradiometric data showing the energy per wavelength produced by their lamps. This data will allow growers to accurately compare different lighting technologies-whether HPS vs.
LED or different LED horticultural lights-and know how much usable light their plants will receive from each system. BestVA's Full Spectrum As Sunlight, Beat Traditional LED grow lights.
Lighting is as important for plants as it is for humans. When you can't provide real sunlight, our LED grow lights provide an excellent alternative, but the wrong LEDs can do more harm than good. Just think of the effect long dark winter days have on you and how much better it is in summer. It's the same for plants and the right quality and intensity of light does make all the difference. That's where BestVA LED comes into the picture.
We have the best LED grow lights that are designed to provide you richer, healthier yields so that you can get the most out of every harvest. Traditional LED arrays tend to mainly operate in blue and red wavelengths, the main wavelengths that activate photosynthesis. However, over-saturating plants in blue and red light puts the plants into a dormant state with high concentrations of oxygen and energy storage molecules. While this may lead to some healthy plants, you're more often left with immature plants and low yields.
BestVA LED grow lights are designed to mimic real sunlight to offer a full spectrum of light. This allows your plants to go through photorespiration. This essentially forces your plants to work a little harder, which causes them to want to take in more nutrients from the soil and water. The result: healthier plants and larger harvests. BestVA Enhanced Quality Control System.
In order to ensusre that our customers receive a 100% good quality working light we opitimized our QC - system especially in LED Driver inspection and Light Testing process , here are the jobs we do in 2016. LED Driver quality control : according to our experience most LED grow light failed because driver burned.
So we require our LED driver supplier to test all drivers for at least 24hours before delivering to us. Then we will recheck all LED drivers before product assembly.We increased our testing time from 12hours to 24hours , then we will reinspect and pack them with strong plain brown box. Location: 5/F, 3 Building, Zhongtai Techpark, Longhua, Shenzhen, China Number of Production Lines: 5 Number of QA/QC: 2 People.
We are always moving forward towords better LED Grow Light. Here at BestVA, we are rigorously implementing the international quality control system into our production. We strive to create healthy lighting and as such, we are constantly ensuring our products are in accordance with the requirements for environmental protectionof ROHS and CE directives.We are Equipped with advanced production facilities and production lines, we closely observe the latest trends at home and abroad to continuously improve ourproducts in innovation and design. Please do NOT write your address in the note part. We accept return in 60days after purchasing. Our products are guaranteed for a period of 3 years under normal use. We cover all repair or replacement cost of device due to product dysfunction under normal use for a period of 3 years. Thanks you very much in advance.
