The price difference of led filament bulbs is so large: Compared with incandescent lamps, the advantages of fluorescent lamps are that they are more energy-efficient, more environmentally friendly, and have a longer life. They are increasingly popular among consumers in the market. There are more and more manufacturers of filament light bulbs, and competition is becoming fiercer. The so-called insider looks at the door and outsiders look lively, so ordinary consumers can only distinguish products by the appearance, structure and function of the manual, and the appearance and structure of the product are almost twice or more the price of two or three. Confusing.

1. Chip

This chip is the core of the LED filament bulb. Whether it can shine depends on it. The price difference between different chips is very large. The price of chips imported from the United States and Japan is higher, while the price of LED chips imported from Taiwan and the mainland is lower. At the same time, the size of the chip is also very important. In general, the quality of large-chip LED filament bulbs is better than that of small chips. The chip size is proportional to the price.

2. Shell

In the process of using LED lamps, led filament bulbs will inevitably generate a lot of heat, which is mainly dissipated through the outer shell to ensure the normal use of the lamp. Therefore, high-quality lamp housings can make a big difference in price.

3. Drive power

The driving power is equivalent to the heart of the LED filament bulb. Power quality will affect the life and brightness of the lamp.

4. The wavelength of light

LEDs with the same wavelength have solid colors and are relatively expensive. It is usually measured using an LED spectrophotometer.

The quality of the LED filament bulb is affected by the quality of the various components of the LED bulb. Therefore, when choosing LED bulbs, you also need to check whether the customer reputation of the LED bulb brand is good. Before judging the quality of a product brand, we need to understand the factors that affect the product quality in advance.
