LED plant lighting involves a variety of disciplines, including semiconductors, spectroscopy, biology, etc., and there are certain technical barriers to entry. LED plant lighting factory is still in the cognition and running-in period in The Chinese market. It will be cheaper when LED plant lighting market opens.
LED chips for lighting are more than N times as expensive as those for plant lamps. If the number of plant lamps is large enough, the price of lamp beads will be about the same as those for lighting.
In addition, the red and blue ratio of the plant lamp, in the case of the right wavelength, power enough, can only ensure that the plant can live, but can not guarantee that the plant live well.
With regard to red (or any other color), there should be a large error in the color observed by the naked eye, such as 650nm light and 640nm light, which the human eye may not be able to see (below, just look at the wavelength and color). However, the actual LED lights that generate a specific band of light cost different light colors, since there is no specific light color data required by plants, it is not clear here.
About the cost of LED lights. The main cost of LED lamp comes from several aspects, such as chip, bracket, gold wire, phosphor (some are more expensive), power supply, etc. The lamps and lanterns of conscientious manufacturer are better in each respect, do not have good manufacturer that is to have no integrity.
Whether LED plant lamp is more expensive than ordinary LED, I think it mainly depends on the wavelength required by plant LED (some wavelength light technology is more difficult to achieve, high cost), I do not know the biological knowledge, can not answer. What’s more, if the core technology of specific wavelengths needed by plants is in the hands of fewer people, it will also have a big impact on the pricing of LED for plants.
