1. The packaging protection of the LED batten light is not perfect, causing the lamp beads to be damaged by impact during transportation.
2. The solder joints of the LED batten light have a phenomenon of virtual soldering. The vibration during transportation causes the solder joints to fall off and the light bar does not light up.

3. LED batten light has a small amount of solder, and the solder joints are easy to fall off. The quality of the solder is not good, and the solder joints of the LED flexible light bar are prone to brittle cracking and falling off during the bending process.
4. When the LED batten light is installed, the bending angle is too large, which causes the solder joint of the LED flexible light bar to separate from the copper foil, resulting in no light.
5. Excessive squeezing of the product when installing the LED batten light will damage the LED flexible light bar chip or cause the solder joints to deform and fall off without lighting.
6. The solder resist layer of the circuit board of the LED batten light is too thick, and the solder and the circuit board cannot be completely fused together during soldering, which is also a phenomenon of virtual soldering.
7. The LED batten light cannot be twisted during installation. If it is twisted, the solder joints of the LED flexible light bar will fall off and cause no light.
Through the above introduction and analysis of the reason why the LED batten light does not light up, hope it helps you.
