Fluorescent lamps, high-pressure sodium lamps and other plant lights have also been brilliant, and still have a certain market position, but in front of LED plant lights, their ten disadvantages are also very obvious:
(1) The lifespan is short. Due to technical reasons, the lifespan of fluorescent lamps has not exceeded 10,000 hours after all, and the lifespan of sodium lamps is also about 30,000 hours. The average life of LED plant lights can easily reach 50,000. About hours
(2) Electro-optical conversion efficiency, the highest intelligent conversion efficiency of traditional plant lights is about 15%, and LED plant lights can be well controlled between 20-30%;
(3) In terms of environmental protection, traditional plant lights cannot be recycled, and some lamps produce harmful gases, while LED plant lights do not;
(4) Temperature control. The surface temperature of traditional plant lights is very high, which is not conducive to supplementing light with plants at close range. LED plant lights can make up for this defect;
(5) Light utilization. After the traditional plant lights are converted into light, only part of them can be used to supplement light for plants, and a large part of them is invalid light for plants. LED plant lights can be customized with wavelengths and almost only emit plant growth. The required spectrum.
Combining all the above, although traditional plant lights still survive in the entire plant lighting market due to their price advantages, they are destined to be eliminated. Like incandescent lamps, they were once a global luxury item and are now a rut of the wheel of history. The development of things is only a matter of time.
