Common Problems and Solutions of common Flex LED strip
1. Please check if power supply is connected, or if the switch is in the connected position when the light does not work.
2. If the lamp lights on and off frequently, please check connection between power supply and strip in case that it is loose.


Note: If the SMD3528 flexible LED stripe light still don't work well after trying the methods above, please contact professionals' staff for help.
1. Please make LED drivers compatible with flexible LED strips before use LED strips; 
2. To use LED light strips 5M in serial, longer than 5M in parallel; 
3. Before use, first check the power supply used in compliance with of the power requirements; 
4. Each roll ask for independent power supply; not to use of multi-volume series use; 


Safety and Maintenance Information
1. SMD LED ribbon itself and all its components may not be mechanically stressed.
2. Don't damage or destroy conducting paths on the circuit board while installation.
3. To guarantee safety, only qualified personnel are allowed to install LED strips.
4. Make sure SMD LED ribbons are mounted to correct electrical polarity.
5. Parallel connection is highly recommended for its high safety.
6. Serial connection is not recommended because unbalanced voltage drop may damage SMD LED strips.
7. Insufficient and unstable power supply may cause flexible strip damage.
8. Don't install SMD LED ribbons directly on metallic or any other conductive surfaces.
