Analysis of factors affecting the price difference of LED lamps

The LED lighting industry is developing rapidly, and there are many kinds of lamps and lanterns, and the price difference is also quite obvious. There are many manufacturers producing LEDs and LED lighting. Different manufacturers use different quality LEDs, which is an important reason for the difference 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, it is difficult for LED lighting manufacturers that do not produce LED light-emitting tubes 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. Wavelength

LEDs with consistent wavelengths have consistent colors. If you require consistent colors, the price will be high. It is difficult for manufacturers without LED spectrophotometers to produce products with pure colors.

4. 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.

5. 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.

6. 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.

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.
