LED Lights Buy
1, LED intensity (MCD), the prices are different. LED for LED lamps shall comply with laser level class I standards.
2, antistatic antistatic ability LED, long life and high prices. Antistatic usually greater than
700V LED can be used in LED lighting.
3, consistent wavelength LED, same color, same color if required, higher prices. No LED light color meter manufacturers is difficult to produce color products.
LED 4, leakage current is a one-way electric light, if there is a reverse current, it is called leakage, leakage current of LED, short life, low prices.
5, LED beam angle of beam angle for different purposes are different. Special angle, the higher the price. Such as the scattering angle, the higher the price.
6, life quality is the key to life, life determined by the light failure. Lumen maintenance, long life, long life, high price.
LED light for 7, wafer chips, different chips, prices vary widely. Chips is more expensive in Japan, America, Taiwan and domestic chip prices generally lower than that of Japan, the United States (CREE).
8, chip wafer size is expressed in length, chip LED the quality is better than a small chip. Price is proportional to the chip.
9, Colloid ordinary LED colloid usually epoxy resin, reinforced with a UV-resistant and fireproofing agent LED to higher prices, high quality LED outdoor lighting should be UV-resistant and fire retardant. Each product has a different design, different design for different purposes, the reliability of the LED lighting designs include: electrical safety, fire safety, the application of environmental security, safety, health and safety, security, time, and other factors. From the electrical point of view, should be in conformity with the relevant international and national standards.
