/n1: leds vary in brightness and price. The LED used for LED lamps and lanterns shall be suitable for the Class I standard of laser grade./n/n/n/n2: anti-static ability of strong LED, long life and therefore high price. Generally anti-static more than 700V of the LED can be used for LED lighting./n/n/n/n3: the wavelength affects the color of the LED, if the color is required to be the same, then the price is high. It is difficult for manufacturers without LED spectrometers to produce products with pure color./n/n/n/n4: Leakage Current, LED is a one-way conductive light, if there is a reverse current, it is called leakage, leakage current of large LED, short life, low price./n/n/n/n5: light-emitting angle, the use of different LED light angle is not the same, specific light-emitting angle higher prices./n/n/n/n6: life, different quality is the key to life, life by light decay. Light Fade Small, long life, high price./n/n/n/n7: Chip, LED light for the chip, different chip, the price varies greatly. Japan, the United States of the chip more expensive, generally Taiwan’s chip price is lower than Japan, the United States, the lowest domestic/n/n/n/n8: colloid, ordinary LED colloid is generally epoxy, with anti-uv and fire retardant LED more expensive, high-quality outdoor LED lighting should be anti-uv and fire./n/n
