What are the main classifications and applications of plant growth lights?

Classification of plant growth lamps The global plant growth lamp market is divided into four major categories, mainly fluorescent lamp growth lamps, LED plant growth lamps, high pressure sodium (HPS) growth lamps, incandescent lamps and halogen lamps.
By 2020, the global LED growth lamp market will reach 1.9 billion US dollars, with a compound annual growth rate of over 25%. The LED growth lamp market is relatively new, and the technology has been developing, and more efficient products have been continuously introduced. The life span of LEDs is 10 times longer than that of ordinary energy-saving lamps, and far exceeds that of ordinary incandescent lamps. Although this type of lamp is more expensive, it is more efficient because it does not need to be replaced frequently, and it also saves electricity costs. LED lamps have a lifespan of up to 11 years. Compared with other lamps, LEDs generate less heat, thus eliminating the cost of expensive and complicated cooling systems. The use of other lamps requires a cooling system, because too high temperature will damage plant tissue cells.
As LEDs have more advantages, researchers around the world are focusing on promoting the research and development of LED plant growth lights, and the market will therefore grow further.
Fluorescent grow lamp market
By 2020, the global fluorescent lamp grow lamp market is expected to reach 1 billion US dollars, and such products are very popular with home gardeners. Standard fluorescent lamps are usually used for seed germination, but the efficiency is not high. In order to overcome the shortcomings of standard fluorescent lamps, advanced technology will cooperate to produce high-yield and efficient fluorescent lamps. Compared with standard fluorescent lamps, the newly developed fluorescent lamps illuminate stronger but have a lower temperature. Such products are more effective and cost-effective than incandescent lamps.
In addition, the fluorescent lamp bracket will also be lighter and easier to install, making it more convenient for users to use, and the bulb can be replaced at any time.
High pressure sodium lamp growth lamp market
By 2020, the global market value of high pressure sodium lamp growth lamps is expected to reach 157 million US dollars. The orange and red light from high-pressure sodium lamps can make flowers produce, bear fruit, and ripen, and they can provide sufficient lighting for the greenhouse. The advantage of the high-pressure sodium lamp is that the irradiation range is wide, and the high-pressure sodium lamp should not be too close to the plants, because it generates a lot of heat. But the greenhouse does need more heat in winter. After the high pressure sodium lamp is used for a long time, the irradiation will become weak, and it needs to be replaced. The average life span of such lamps is 18,000 hours.
According to Technavio Agricultural Equipment Analyst Abhay Sinha, “High-pressure sodium lamps have the highest efficiency among all high-intensity gas discharge lamps. The luminous efficiency of high-pressure sodium lamps is 6 times higher than that of incandescent lamps. There is a big difference. Conducive to promoting the growth of the indoor cultivation industry."
Incandescent lamp and halogen lamp growth lamp market
The global incandescent lamp and halogen lamp growth lamp market value will reach 79.5 million US dollars by 2020, with a compound annual decline rate of 1.5%.
Incandescent lamps are usually available in grocery stores and hardware stores, but one disadvantage of using incandescent lamps as growth lamps is that they do not save energy. The part of the energy that does not produce light will generate extra heat. Abhay said: "Although I just started buying incandescent lamps The cost is very low, but the operating cost is higher than that of fluorescent lamps. Therefore, it is not suitable to use incandescent lamps as growth lamps, and so are halogen lamps, because their performance is similar to that of incandescent lamps."
