1. Since LED is a constant current component, the constant current effect of LED light strips produced by different manufacturers is different, and the life span is therefore different.

2. The poor toughness of the copper wire or flexible circuit board of the LED light strip will cause the LED light strip to break when it is bent, and will also affect the life of the LED light strip.

3. For power supply, LED light strips are generally powered by constant voltage power supply (DC switching power supply). If the output of the power supply is unstable or there is no surge protection, it will output unstable voltage and current when the external network voltage fluctuates, causing LED light strips to work at non-standard voltage, which will also affect their service life.
