2025-07-01
Flickering of the light strip is a common problem for many users. As a professional LED lighting solution provider, Shenzhen Jomo Lighting Technology Co., Ltd. analyzes the 5 most common reasons and solutions for you to help you quickly restore the normal use of the light strip.
1. Power supply problem
Insufficient power or unstable voltage of the power adapter is the primary cause of flickering of the light strip. Jomo Lighting recommends checking:
· Whether the power supply matches the power demand of the light strip
· Whether the output voltage is stable
· Whether the power cord is firmly connected
Solution: Replace the power adapter that meets the specifications to ensure stable voltage.

· Check whether the controller interface is loose
· Pay attention to whether the copper foil contacts of the light strip are oxidized
Solution: Re-fix the connection and replace the connector if necessary.

5. Environmental interference factors
Electromagnetic interference or abnormal temperature can also cause flickering:
· Are there high-power electrical appliances nearby?
· Is the installation environment temperature too high?
· Is the line parallel to the strong wire?
Solution: Improve the installation environment and increase shielding measures.
