The difference between high-voltage light strips and low-voltage light strips

 1. Safety: High-voltage LED light strips operate at a voltage of 220V, which is a dangerous voltage and may cause safety hazards in some risky situations. Low-voltage LED light strips operate at a DC 12V operating voltage, which is a safe voltage and can be used in various applications. In this case, there is no danger to the human body.

 2. Installation: The installation of high-voltage LED light bars is relatively simple and can be driven directly by a high-voltage driver. Generally, it can be configured directly in the factory and it can work normally when connected to the 220V power supply. The installation of low-voltage LED flexible light strips requires a DC power supply in front of the light strips, which is relatively complicated to install.

 3. Price: If you look at the two types of light strips alone, the prices of LED light strips are about the same, but the overall cost is different, because high-voltage LED light strips are equipped with high-voltage power supplies. Generally, one power supply can last 30~ 50-meter LED flexible light strip, and the high voltage cost is relatively low. Low-voltage LED light strips require an external DC power supply. Generally, the power of a 1-meter 60-bead 5050 light strip is roughly 12~14W, which means that each meter of light strip must be equipped with a DC power supply of about 15W. In this way, the low-voltage LED light strip The cost will increase a lot, much higher than that of high-voltage LED light strips. Therefore, from the overall cost point of view, the price of low-voltage LED lights is higher than that of high-voltage LED lights.

 4. Packaging: The packaging of high-voltage LED light strips is also very different from that of low-voltage LED light strips. High-voltage LED flexible light strips can generally be 50 to 100 meters per roll; low-voltage LED light strips can generally be up to 5 to 10 meters per roll. ; The attenuation of DC power supply beyond 10 meters will be severe.

 5. Service life: The service life of low-voltage LED light strips will technically be 50,000-100,000 hours, but in actual use it can also reach 30,000-50,000 hours. Because of the high voltage, high-voltage LED light strips generate much more heat per unit length than low-voltage LED light strips, which directly affects the life of high-voltage LED light strips. Generally speaking, the service life of high-voltage LED light strips is about 10,000 hours.

6. Application scenarios: Because the low-voltage flexible light strip is very convenient to use, after tearing off the protective paper from the adhesive backing, you can stick it in a relatively narrow place, such as a bookcase, showcase, wardrobe, etc. The shape can be changed, such as turning, arcing, etc.

 High-voltage light strips are generally equipped with buckles for fixed installation. Since the entire lamp has a 220V high voltage, it would be more dangerous if the high-voltage lamp strip is used in places that can be easily touched, such as steps and guardrails.Therefore, it is recommended that high-voltage light strips be used in places that are relatively high and out of reach of people.

 It can be seen from the above analysis that high and low voltage LED light strips have their own advantages and disadvantages. Users are asked to make reasonable choices according to their different use environments so as not to waste resources.
