Brightness
Different brightness and price of LED.
Antistatic ability
LED with strong antistatic ability has long life and high price. Generally, LED with antistatic capacity greater than 700V can be used in LED automobile lighting products.
Wavelength
LED with the same wavelength has the same color. If the same color is required, the price will be high. It is difficult for manufacturers without LED spectrophotometer to produce pure color products.
Leakage current
LED automobile lamp is a single-guide light emitter, if there is a reverse current, it is called leakage current. LED with large leakage current has short life and low price.
Light-emitting angle
LED automobile lamps with different uses have different light-emitting angles. Special light-emitting angle, the price is higher. If full diffuse angle, the price is higher.
Chip size
The size of the chip is expressed by the side length. The quality of large chip LED is better than that of small chip. The price is proportional to the size of the chip.
Life
The key to different qualities is life, which is determined by light decay. Low light decay, long life, long life and high price.
LED chip
LED automobile lamp luminous body is the chip, different chips, the price of LED lamp controller varies greatly.
Colloid
The price of LED with anti-ultraviolet and fire retardant is more expensive. The colloid of ordinary LED automobile lamp is epoxy resin. High-quality outdoor LED lighting should resist ultraviolet and fire. In addition, some dishonest manufacturers still exist in the LED lighting market, cheating suppliers to produce finished products and selling them at abnormal low prices. Goods in exchange for cash cheat suppliers.
