What are we suggesting for your greenhouse lighting
All of our light products have CE, ROHS e FCC certificates.
The material used is aluminum which lets the greatest cooling of the led itself and a long life of 50000 h.
The device (IP65) has a protection level that can withstand water and dust and Its charger and junctions are in the same IP65 that avoid infiltration problems.
Chip LED Epistar / Ledstar, leader brand for qualities in the sector.
With this product, we have determined, through our present knowledge that the spectrum ideal for growth and flowering of the plant , is: Our relationship to 115 cm / 36 chip LED bar proposal, is:
Red / Blue / Green/ IR 24 / 6 / 2 / 4
What is the lamp spectrum
Plants have a different perception of the light, they recognise different wavelenghts from human beings. Only a small part of the light, that human can see, contribuites to the plant growing (photosynthesis), the light with a wavelenghts between 400 and 700 nm. Generally the blue led is used in the growing phase and the red led in the flowering phase. Our led bar uses a mix of red,blue and green light that is adapted for both the phases and the germination too. The bar placed at the right height, different for each kind of cultivation, will be very usefull during the growing and flowering phases.
Led technology lets to choose in the range 400-700 nm the wavelenght that is more suitable for our plants. Wavelenghts important for cultivators are:
439 nm is the absorption peak by chloropyll A and It is related to blue.
450-460 nm is royal blue, beta-carotene absorption peak. This is a wavelength very common and used to stimulate phosphorus in lamps with white Led.
469 nm is the absorption peak by chloropyll B and It is related to blue.
430-470 nm is a very important range for the absorption of chlorophyll A and B, central factor for the vegetative growing.
480-485 nm is the other beta-carotene absorption peak.
525 nm (green light) is a phototropic activator very studied by reasearchers. Green light isn t important for the photosynthesis, but It is proved that plants are influenced by it for orientation and signal level. (This wavelenght is used in RGB products)
590 nm is important for carotenoids absorption. (Nutritional compounds used to preserve starch and the plant structure)
590 nm is also related to phycoerythrin absorption, a red protein and a complex pigment essential for the light absorption. It is present in red seeweeds and cryptophytes. Moreover is the the principal accessory pigment of the chlorophyll and It is the responsible of photosynthesis.
625 nm is phycocyanin absorption peak, a complex pigment of pico bili family, a protein essential for light absorption and chlorophyll.
642-645 nm is the absorption peak of chlorophyll B.
660 nm is commonly known as super-red Led and It is very important for the flowering phase.
666-667 nm is the red absorption peak of chlorophyll A.
700 nm is a wavelength that is better to avoid, according to the researches It confuses the phytochrome recycling system of the plant. Phytochromes are photoreceptor that are perceivable to the light in the area of red/far red of the spectrum.
730 nm is called far red and It is important for the phytochrome recycling: It is essential for every kind of morphogenetic development. Only few minutes of treatment of this wavelenght, after the finish of the radiation cycle, change the chromophore from active to passive: this process creates the chemistry for another radiation cycle and It could be useful to shorten the classic dark period of photoperiod. This colour is important for plants although is over PPF range 400-700 nm.
