There are many manufacturers producing LEDs and LED lighting. Different manufacturers replace different quality LEDs is an important reason for different LED lamps. Due to the increasingly fierce price war, products with almost the same appearance, structure, and functions, but the price difference is 2-3 times, many users are dazzled for a moment, I do not know where the price difference comes from, and generally do not produce LED lighting manufacturers of LED lighting tubes It’s hard to distinguish, let alone consumers.

Therefore, it would be better to replace the LED lighting factory with a good source of LED production, or have a complete LED testing equipment, so that the LED lighting products purchased will be guaranteed.

Let’s see what factors cause the price difference of LED lamps:

1, Brightness
LEDs have different brightness and prices.

2,Antistatic ability
LEDs with high antistatic ability have a long life and are therefore expensive. Generally, LEDs with an antistatic capacity greater than 700V are used for LED lighting.

3, Wavelength
LEDs with the same wavelength have the same color. If the color is required to be the same, 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 light emitter. If there is reverse current, it is called leakage. LED with large leakage current has short life and low price.

5,Light angle
LEDs with different uses have different light emitting angles. Special lighting angle, the price is higher. Such as full diffusion angle, the price is higher.

6, life
The key to different qualities is life, which is determined by light decay. Light decay is small, long life, long life and high price.

7, LED chip
Chips in Japan and the United States are more expensive, and LED chips from Taiwanese manufacturers and Chinese domestic manufacturers are less expensive than Japan and the United States.

8, chip size
The size of the chip is expressed by the side length, and the quality of the large chip LED is better than that of the small chip. The price is directly proportional to the chip size.

9, colloid
Ordinary LED colloids are generally epoxy resins. LEDs with anti-ultraviolet and fireproofing agents are more expensive. High-quality outdoor LED lighting should be UV-resistant and fireproof.
