When the T5 lamp is used, it will produce some electromagnetic waves and microwaves. Contains mercury and may have ultraviolet leakage; And many Chinese workers have suffered mercury poisoning from making energy-saving lamps. Light decay, after a long time, the luminosity will be lower than the new product, most of them can not be dimmed, and it is not suitable for dimmable brightness lamps. It is not suitable for occasions where frequent switching is required, and LED or CCFL lighting is better in these occasions. Low color rendering: incandescent and halogen lamps have a color rendering of 100, which is perfect; Most of the color rendering of energy-saving lamps is between 80 and 90, of course, the price is its advantage, and the price ratio of the other two lamps is undoubtedly a huge advantage. Poland Led Grow Light, Grow Light 240W , Light Rail Grow , Led Grow Light Distance ,Grow Light Spectrum . Compared with traditional lighting, the advantages of LED indoor lighting plant lights are embodied in the following aspects: The product will supply to all over the world, such as Europe, America, Australia,Tajikistan, Milan,Australia, Istanbul.In the past, the cost of LED lighting remained high, so plant factories mostly use fluorescent tubes or high-pressure sodium lamps, with the decline in LED prices and technological improvement, the application of LED in plant factories has seen a new wave of progress. At present, there are not many manufacturers engaged in LED grow lights in China, most of which are concentrated in Shenzhen.
