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. Hydroponic Led Grow Light, Led Greenhouse Grow Light , Dim Grow Light , 630W Cmh Grow Light Kit ,Pink Led Grow Light . LED is used as a light source for indoor lighting, and there are still certain problems with lighting effects. The efficiency, color and service life (attenuation of light) of individual luminaires, as well as the quality of illumination, are not ideal. Although LED illumination is very high and energy consumption is very low, this does not mean that the efficiency of LED lamp light is high, because its overall lighting quality is not high. In addition, LED lighting fixtures need to avoid too strong glare LED grow light features and introduction. Only when the temperature is suitable LED lighting fixtures can be very long, once made into poor quality lamps, in high temperature and closed environment, the lighting effect will drop sharply. The product will supply to all over the world, such as Europe, America, Australia,Jamaica, Iraq,India, Detroit.In fact, organic cultivation is not completely without fertilizer, but what can be used is organic fertilizer: farm fertilizer, mineral fertilizer, biological bacteria fertilizer, etc. after high-temperature fermentation and harmless treatment. Based on the limitations of this fertilization, the growth cycle of plants must be affected, and the current market demand is in short supply, so shortening the production cycle is one of the methods.
