What factors cause the price difference of LED lamps

The continuous development of the lighting industry, LED lamps and traditional lamps continue to compete. There are many manufacturers of LED and LED lighting. Different manufacturers use different quality LEDs, which are the important reasons for LED lamps. Due to the increasingly fierce price war, the products with almost the same appearance, structure and function have a price difference of 2-3 times. Many users have been stunned for a while, and they do not know where the price difference comes from. Generally, LED lighting manufacturers that not only who produce LED lighting tubes that is hard to distinguish, let alone consumers.

Therefore, it is better to choose a good LED production source, or an LED lighting factory with perfect LED testing equipment, so that the purchased LED lighting products will be more secure.

Let's see what factors are causing the price difference between LED lamps:

1, brightness

The brightness of the LEDs is different and the price is different.

2, antistatic ability

LEDs with strong antistatic properties have a long life and are therefore expensive. LEDs with an antistatic greater than 700V are usually used for LED lighting.

3, wavelength

LEDs with the same wavelength have the same color. If the color is the same, the price is high. It is difficult for manufacturers without LED spectrophotometers to produce pure color products.

4, leakage current

LED is a unidirectional conductive illuminator. If there is reverse current, it is called leakage, LED with large leakage current, short life and low price.

5, the angle of illumination

LEDs with different uses have different illumination angles. Special lighting angle, the price is higher, such as full diffusing angle, the price is higher.

6, life

The key to different qualities is life, and life is determined by light decay. Low light decay, long life, long life and high price.

7, LED chip

The illuminator of the LED is a chip, and the price of the chip varies greatly. The chips in Japan and the United States are more expensive, and the price of LED chips from Taiwanese and Chinese manufacturers is lower than that of 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 proportional to the chip size.

9, colloid

The colloid of ordinary LED is generally epoxy resin, and the LED with anti-ultraviolet and fire retardant is more expensive. The high-quality outdoor LED lighting should be resistant to ultraviolet rays and fire.

There are still some illegal people in the LED lighting market, deceiving suppliers, defrauding suppliers of materials to produce finished products, and selling finished products at abnormally low prices in exchange for cash. There are also a handful of LED lighting manufacturers that deceive dealers and users with unrealistic promises, and then use the tactics of constantly changing the firm or the person in charge to shirk responsibility. Therefore, consumers must pay attention to these details when purchasing.
