What is the difference between low-voltage LED strips and high-voltage strips?
Common LED lights have high-voltage LED strips and low-voltage LED strips. High-voltage LED strips are also called AC strips, and low-voltage LED strips are also called DC strips. What is the difference between these two flexible LED lights? Which one would you choose?
The 220V voltage used by high-voltage LED light strips is a dangerous voltage, and there are potential safety hazards in some risky applications; low-voltage LED light strips to work under a DC 12V working voltage, which is a safe voltage and can be used in various occasions. There is no danger to the human body.
The packaging of high-voltage LED strips and low-voltage LED strips are also very different. High-voltage LED flexible strips can generally be 50-100 meters per roll; low-voltage LED strips generally can be up to 5-10 meters per roll; more than 10 meters The above DC power supply attenuation will be very severe.
3. Convenience of installation
The installation of a high-voltage LED light bar is relatively simple, and it can be directly driven by a high-voltage driver. Generally, it can be configured directly in the factory, and it can work normally after turning on the 220V power supply. The installation of the low-voltage LED flexible light strip requires the installation of a DC power supply in front of the light strip, which is relatively complicated during installation.
4. Service life
The service life of low-voltage LED strips will technically be 50000-100100 hours, and actual use can also reach 30000-50010 hours. Because of the high voltage, high-voltage LED strips to generate much more heat per unit length than low-voltage LED strips, which directly affects the life of high-voltage LED strips. Generally speaking, the service life of high-voltage LED strips is about 10,000 hours.
If you look at the two types of lights alone, the price of LED strips is similar, but the overall cost is different because high-voltage LED strips are equipped with high-voltage power supplies. Generally, one power supply can carry 30-50 meters of LED flexibility. Lightbars, and, relatively speaking, the cost of high-voltage voltage is relatively low. Low-voltage LED strips to need to be equipped with a DC power supply. Generally, the power of a 1 meter 60-bead 5050 strip is roughly 11~14W, which means that each meter of the strip needs to be equipped with a DC power supply of about 15W. The cost will increase a lot, which is much higher than the high-voltage LED strip. Therefore, from the overall cost point of view, the price of low-voltage LED lamps is higher than that of high-voltage LED lamps.
