When you buy LED lamps what will pay attention!

LED Light

With the fast development of the lighting industry, LED lamps have always competed with traditional lamps. There are many manufacturers who producing LEDs and LED lighting. Different manufacturers choose LEDs of different quality is an important reason for the differences in LED lamps. Due to the increasingly fierce price war, the price difference of products with almost the same appearance, structure and function is 2-3 times. Many buyers are confused when they buy. It is difficult to distinguish, let alone consumers.

Therefore, it is more reliable to choose a good source of LED production, or an LED lighting factory with complete LED testing equipment, so that the LED lighting products bought will be more secure. So what is reason for the price difference of LED lamps?

1. Brightness. The brightness of the LED is different, and the price is naturally different.

2. Antistatic ability. LEDs with strong antistatic ability have a long life and are therefore expensive. Normally, only LEDs with antistatic voltage greater than 700V can be used for LED lighting.

3. Luminous angle. LEDs with different purposes have different light-emitting angles. Special lighting angle, higher price. Such as full diffusion angle, the price is higher.

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

5. Wavelength. LEDs with the same wavelength are expensive if the colors are the same. It is difficult for manufacturers without LED spectrophotometers to produce products with pure colors.

6. Leakage current. LED is a unidirectional conductive luminous body. If there is a reverse current, it is called leakage. LEDs with large leakage current have short life and low price.

7. LED chip. The luminous body of the LED is a chip, and the price of different chips varies greatly. Chips in Japan and the United States are more expensive, and the prices of LED chips from Taiwanese and Chinese manufacturers are lower than those in 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 size of the chip.

9. Colloid. The colloid of ordinary LEDs is generally epoxy resin. LEDs with anti-ultraviolet and fire retardants are more expensive. High-quality outdoor LED lighting should be anti-ultraviolet and fireproof. There are still some illegal gangsters in the LED lighting market, concealing 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 small number of LED lighting manufacturers who deceive dealers and customers with unrealistic promises, and then use the trick of constantly changing business names or responsible persons to shirk responsibility. Consumers must pay attention to these details when buying.
