The effect is quite significant, growing 3 times faster than the natural growth of plant. it help plants boost of photosynthesis at dark indoor and basement ect.
The best proportion of red and blue of LED Growth Light is from 4: 1 to 9: 1 in general. When the LED Grow Light supplements light to the plant, the general height is about 1.7ft from the blade. Continual 10 hours per day light exposure can completely replace the sunlight.
The plant photosynthesis requires light wavelength 400-700nm, among which 400-500nm (blue) light and 610-720nm (red) make the greatest contribution to photosynthesis. Blue (460nm) and red (660nm) of the LED provide the exact light for plants. Blue light promote leaves growth and red light accelerates blooming and bearing fruit and extend the flowering period. Therefore, the ideal option of LED Grow Light it to combine two or more colors. The visible color of red and blue is pink.
6pcs 660nm LED, 3pcs 630nm LED, 3pcs 460nm LED, The light wavelength totally absorbed by the plants photosynthesis. This LED grow light with long lifespan. Enhanced passive cooling system allows for reduced junction temperature, even 24 hours a day.
Its wavelength is ideal for plant growth, LED Grow Light with the spectrum required not only promotes their growth, but also extends the flowering period and improves the quality of flowers, To apply this highly efficient light source system to the greenhouse and other facilities of agricultural production.

Product Description
LED Grow Lights Technology:
LED Growth Light adopts the technology of semiconductor lighting technology which is dedicated to the growth of vegetables and flowers. The wavelengths of red and blue are more suitable for the growing, blooming and bearing fruit of vegetables and flowers. The blue light is conducive to the growth of leaves while the red light is to the blooming and bearing fruit. With the high power and the high brightness HIGH POWER LED technology, our 12W Growth Light can reduce energy consumption greatly. The single HIGH POWER LED enjoys long life and wide light angle. Glare-type plant lights can grow ornamental flowers, potted plants strawberries, low-growing vegetables and fruits and cuttings of tomatoes.
Light wave effect on plant growth:
280~315nm Minimal effect on Morphological and physiological processes
315~400nm (Violet) chlorophyll of absorption less, influencing light cycle effect, prevent stem elongation
400~520nm (Blue) chlorophyll and carotenoid absorption maximum, greatest effect on photosynthesis
520~610nm (Green) pigment absorption rate is low
610~720nm (Red) chlorophyll absorption rate is low that significantly affects photosynthesis and photoperiod
720~1000nm IR infrared absorption rate is low, prevent cell elongation, affect flowering and seed germination
1000nm converted into heat
8000~14000nm Far Infrared
