1: Different LED brightness and different prices. LEDs used in LED lamps should be suitable for laser class I standards.
2: LED with strong antistatic ability, long life and high price. Generally, LEDs with antistatic greater than 700V can be used for LED lighting.
3: The wavelength affects the color of the LED. If the color is required to be consistent, the price is high. It is difficult for manufacturers without LED spectrophotometers to produce products with pure colors.
4: Leakage current, LED is a unidirectional conductive luminous body, if there is reverse current, it is called leakage, LED with large leakage current, short life and low price.
5: Light angle, LEDs with different uses have different light angles, and specific light angles are more expensive.
6: Lifetime, the key to different qualities is lifespan, and lifespan is determined by light decay. Low light decay, long life and high price.
7: Wafers, LED luminous bodies are wafers, different wafers, the price varies greatly. The chips in Japan and the United States are more expensive.Generally, the price of chips in Taiwan is lower than that in Japan and the United States.
8: Colloid, the colloid of ordinary LED is generally epoxy resin, the price of LED with anti-ultraviolet and fire retardant is more expensive, high-quality outdoor LED lighting should be resistant to ultraviolet and fire.
