How do you judge the LED light source? What are the main features?
Antistatic ability, antistatic ability of LED, long life, and thus high prices. Usually antistatic 700V than LED can be used for LED lighting.
LED with different angles of illumination has different luminous angles. Special light angle, higher price. Such as full diffusion angle, higher prices.
Leakage current LED is a one-way conductive light, and if there is reverse current, it is called leakage, leakage current of large LED, short life, low price.
LED of the same wavelength and wavelength. The color is the same. If the color is the same, the price is high. It is difficult for manufacturers without LED spectrophotometer to produce pure color products.
Brightness LED brightness is different, the price is different. The LED for the LED luminaire shall comply with the laser class I standard.
