(1) brightness: LED brightness is not the same, the price is not the same.
(2) antistatic ability: anti-static ability of LED, long life, and thus high prices. Usually anti-static greater than 700V LED can be used for LED lighting.
(3) Wavelength: Wavelength consistent LED, the same color, then the price is high. No LED color separation device manufacturers can not produce pure color pure products.
(4) leakage current: LED is a one-way conductive light, if there is reverse current, then known as leakage, leakage current LED, short life, low prices.
(5) light angle: the use of different LED light angle is not the same, a special light angle, the price is higher.
(6) life: the key to different quality of life, life is determined by the light fade. Light fades small, long life, long life, high prices.
(7) Wafer: LED luminous body for the wafer, different chips, the price difference is very large. Japan, the United States, the higher the price of the chip, the general production of Taiwan and mainland China chip prices are relatively lower than Japan, the United States and other countries.
(8) chip size: the size of the chip to the side length, large chip LED quality is better than the small chip. The price is proportional to the size of the chip.
(9) colloid: ordinary LED colloid is generally epoxy resin, plus anti-ultraviolet and fire retardant LED more expensive, high-quality outdoor LED lighting should be anti-ultraviolet and fire.
