LED brightness is different, the price is different.
2, anti-static 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, light angle
Use different LED its light angle is not the same. Special light angle, the price is higher. Such as full diffuse angle, the price is higher.
4, life expectancy
The key to different quality is life, life is determined by the light fade. Light fades small, long life, long life, high prices.
Wavelength consistent LED, color consistent, then the price is high. Producers who do not have LED spectrophotometers are difficult to produce pure color products.
6, leakage current
LED is a one-way conductive light, if there is reverse current, then called leakage, leakage current LED, short life, low prices.
7, LED chip
LED luminous body for the chip, different chips, the price difference is very large. Japan, the United States more expensive chip, Taiwan and China's domestic manufacturers of LED chip prices lower than Japan, the United States.
8, chip size
The size of the chip to side length, large chip LED quality is better than the small chip. The price is proportional to the chip size.
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.
