China manufacturer of magnetic ballasts for metal halide flood lights & hps flood lights

The plants grow light source: high pressure sodium lamp, metal halide lamp, ceramic metal halide lamp, microwave sulfur lamp, plasma lamp, fluorescent lamp, no electrode lamp and led. Is the most commonly used sodium lamp, metal halide lamp and LED. Other relatively small minority, price or very expensive high pressure sodium lamp can be divided into ordinary sodium lamp, sodium lamp with high photosynthetic efficiency, plants with sodium lamp, used a 250W, 400W, 600W, 1000W. The current trend is the power of the bigger the better, because it is very simple, a 1000W system than the two sets of 400W system cheap and large coverage effect of common sodium, low prices, low flux, sodium lamp with high photosynthetic efficiency as the name implies, higher luminous flux, but these are not real plants with sodium lamp, is only used as a street lamp only plants with sodium lamp must be high lumen output, with proper spectral; and sodium lamp with high photosynthetic efficiency although high lumen output, but content of red and blue light spectrum is much lower than the plant sodium lamp, no what green is higher plant sodium 7-9 times, only under the effect of a waste of energy. So there are customers ask why growth effect is not obvious, you used the wrong light to high luminous efficiency of the lamp and plant sodium lamp only through spectral analysis and judgment, is not with the naked eye judgment method. This is also present many factories to unscrupulous flicker the majority of farmers, to the consumer brings the reason for the loss of metal halide lamp containing rich blue, and even the spectra of reinforcing the plant sodium lamp. The Blu ray is significantly smaller than that of the metal halide lamp. Used together with sodium lamp and metal halide lamp can reach a perfect effect, however, taking into account the cost, greenhouse or with sodium lamp.

Impact on plant photosynthesis is the largest solar light in the red and blue, sodium lamp and metal halide lamp is continuous spectrum, what light, and LED grow plant light only selection red and blue chip combination, lack of other spectral. So red and blue group together becomes purple different plants on spectra have different needs, such as for lettuce is red / Blue 4:1, strawberry 5:1, universal 8:1, some need to increase the infrared and ultraviolet, but some plants have a smattering of knowledge, the spectra of all together the United States and its fine sounding name full spectrum for any plant, the results which contains ultraviolet to according to the orchid family died, but fortunately not hundreds of thousands of that. White, containing all the spectra and whole white LED, said it is full spectrum, Philips also dry the stupid things. And I did an experiment, the same plant, side by two 200W white, while a 90W UFO (red, blue, 1:1) and 90W square (red and blue 8:1), a week after the white plant significantly compared with red and blue lights grow slowly, not superstition white the up in red and blue lights and a few pieces of white led to improve, rather than as a main lamp LED lumen output is not high.

LED only as far as plants can play a role, it means that the LED is not suitable for high - high hanging in outdoor greenhouse with the application test, the wavelength is very suitable for plant growth, flowering, results. General indoor plant flowers, will grow worse with time, the main reason is lack of light irradiation, the LED grow lights can not only promote its growth, but also to extend the flowering period, improve the quality of flowers. And the high efficiency light source system is applied to agricultural production, such as greenhouse, greenhouse and other facilities,
