Things to note when purchasing LED lamps

The lighting industry is constantly developing, and LED lamps are constantly competing with traditional lamps. There are many manufacturers producing LEDs and LED lighting fixtures. Different manufacturers use different quality LEDs, which is an important reason for the differences in LED lamps. Due to the increasingly fierce price war, products with almost the same appearance, structure, and function have a price difference of 2-3 times. Many users are confused for a while and don’t know where the price difference comes from. Generally, LED lighting fixture manufacturers that do not produce LED light-emitting tubes find it difficult to distinguish, let alone consumers.

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

Let's take a look at the factors that cause price differences in LED lamps:

1. Brightness

LEDs have different brightness and different prices.

2. Antistatic ability

LEDs with strong antistatic ability have long life and are therefore expensive. Usually, only LEDs with antistatic ability greater than 700V can be used in LED lighting.

3. Lighting Angle

LEDs with different uses have different light-emitting angles. Special light-emitting angles have higher prices. For example, full diffuse angles have higher prices.

4. Lifespan

The key to different quality is lifespan, which is determined by light decay. Small light decay means long lifespan, while long lifespan means high price.

5. Wavelength

LEDs with consistent wavelengths and colors are more expensive. It is difficult for manufacturers without LED spectrometers to produce products with pure colors.

6. Leakage current

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

7. LED chips

The light source of LED is chip, and the price of different chips varies greatly. Chips from Japan and the United States are more expensive, while 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. The quality of large chip LEDs is better than that of small chips. The price is proportional to the chip size.

9. Colloid

The colloid of ordinary LEDs is generally epoxy resin. LEDs with anti-UV and fire retardants are more expensive. High-quality outdoor LED lighting should be anti-UV and fireproof.

There are still some illegal people in the LED lighting market who cheat suppliers, use their materials to produce finished products, and then sell the finished products at abnormally low prices in exchange for cash. There are also a few LED lighting manufacturers who deceive dealers and users with unrealistic promises, and then shirk their responsibilities by constantly changing their business names or responsible persons. Therefore, consumers must pay attention to these details when purchasing.
