Good quality of 5050 60leds/m SMD chips with yellow PCB

* The strip itself and all its components may not be mechanically stressed.
* Assembly must not damage or destroy conducting paths on the circuit board.
* Installation of LED ribbon (with power supplies) needs to be made with regard to all applicable electrical and safety standards. Only qualified personnel should be allowed to perform installations.
* Correct electrical polarity needs to be observed. Wrong polarity may destroy the strip.
* Parallel connection is highly recommended as safe electrical operation mode.
* Serial connection is not recommended. Unbalanced voltage drop can cause hazardous overload and  damage the strip.
* Please ensure that the power supply is of adapters power to operate the total load.
* When mounting on metallic or otherwise conductive surfaces, there needs to be an electrical isolation points between strip and the mounting surface.
* Pay attention to standard ESD precautions when installing the strip.
* Damaged by corrosion will not be honored as a materials defect claim. It is the user’s responsibility to  provide suitable protection against corrosive agents such as moisture and condensation and other harmful elements.
