Why are the prices of different solar street lights so different?

With the continuous development of the lighting industry, solar street light is constantly competing with traditional lamps. There are many manufacturers producing LEDs and LED lighting. Different manufacturers choose different quality LEDs, which is an important reason for the difference in solar street lights. 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 users are temporarily confused and do not know where the price difference comes from. Generally, LED lighting manufacturers that do not produce LED light-emitting tubes It's hard to tell the difference, let alone consumers. Therefore, it is better to choose an LED lighting factory that has a good source of LED production, or has a complete LED testing equipment, so that the solar street light products purchased will be more secure. Let's take a look at the factors that cause the price difference of solar street light: 1. Brightness The brightness of the LED is different, and the price is different. Antistatic ability LEDs with strong antistatic ability have long life and high price. Usually LEDs with anti-static greater than 700V can be used for LED lighting. 2. Wavelength LEDs with the same wavelength have the same color. If the same color is required, the price will be high. It is difficult for manufacturers without LED spectrophotometers to produce products with pure color. Leakage current LED is a unidirectional conductive light-emitting body. If there is a reverse current, it is called leakage current. LEDs with large leakage current have short life and low price. 3. Lighting angle LEDs with different uses have different light-emitting angles. Special lighting angle, higher price. Such as the full diffusion angle, the price is higher. 4. Lifespan The key to different quality is lifespan, which is determined by light decay. Low light decay, long life, long life and high price. 5. LED chip The light source of LED is a chip, and the price of different chips varies greatly. Chips from Japan and the United States are more expensive, and the prices of LED chips from Taiwanese and Chinese local manufacturers are lower than those of Japan and the United States. 6. Chip size The size of the chip is represented by the length of the side. The quality of the large chip LED is better than that of the small chip. The price is proportional to the chip size. 7. Colloid The colloid of ordinary LED is generally epoxy resin. The price of LED with anti-ultraviolet and fire retardant is more expensive. High-quality outdoor LED lighting should be anti-ultraviolet and fireproof. 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 few LED lighting manufacturers who deceive dealers and users with unrealistic promises, and then shirk their responsibilities by constantly changing the company name or the person in charge. Therefore, consumers must pay attention to these details when purchasing.
