As the herd of the market, as consumers, use LED tube remains to be calm, scientific analysis, selection of the best cost-effective light sources and lamps, LED Here are a few basic properties:
1, the brightness of different brightness LED tube, the price difference. The LED for the LED tube should meet the standards of Class Ⅰ laser level.
2, the antistatic ability of anti-static ability of the LED tube, long life, and therefore higher prices. Usually greater than 700V of static can be used for LED lighting LED tube.
3, the wavelength of the same wavelength LED, and color, such as requiring the same color, the price is high. No LED spectral separation device manufacturers difficult to produce pure color led tube products.
4, the leakage current is one-way conductive LED tube light, if there is reverse current is called leakage, leakage current is large LED tube, life is short, low prices.
5, uses a different angle light LED tube angle of the light is not the same. Special light-emitting angle, and higher prices. If all diffusion angle, and higher prices.
6, the key to life is the life of different quality, life determined by the light failure. Lumen, long life, long life, high price.
7, LED tube light-emitting chip for the chip body, different chips, prices vary widely. Japan, the United States more expensive chips, the chips made in Taiwan and the general prices are lower than Japan and the U.S..
8, the size of the chip size of the chip to the side of that great quality of LED chips are better than small chips. The chip size is proportional to the same price.
9, colloidal colloidal ordinary LED tube usually epoxy resin, plus a UV LED tube and fire agents more expensive, high quality outdoor LED lighting should be UV and fire. Each product will have different designs, different designs for different uses, LED tube the reliability of the design include: electrical safety, fire safety, for environmental safety, machinery safety, health and safety, safe use of time and other factors. From the electrical safety point of view, should be consistent with relevant international, national standards.
Because LED tube is a new product, China lags behind the national standard, but the countries qualified products tested. With international safety certification (such as GS, CE, UL, etc.) and the national product quality certification of the LED tube prices higher, because these products in the security design is reliable. Consumers to pay attention is to carefully identify the authenticity of the certificate, there is now international and national product safety certification certificates are not many manufacturers.
From health, the use of toxic materials, the prices of products designed to be high, especially in indoor LED tube, do not be cheap used odor of LEDtube, currently only a few LED manufacturers is to use non-toxic materials and the method can identify directly respectively, with the nose, the smell of the products at lower prices than those without a lot of odor. Like lead, mercury, cadmium and other toxins to be professional analysis. From the application of environmental security perspective, a reliable dust-proof design, materials, fire prevention, anti-UV, anti-low-temperature cracking of the LED tube product prices high.
