1. Check in the test lab. We can check the chips, PCB material, brightness, color temperature, and CRI. That is a professional way.
2. Check the led strip light surface.
We can check the soldering point. If the surface is not clear, the led are not soldering in the right place.
The surface is dirty. That is not a good led strip light. Good led strip light, the surface is clear, and the led are soldering in the right place.
3. Check the PCB
Normally, the led strip light PCB has 2 kinds of technology.
Rolled copper, place polygon plane. And they also have a single-side PCB design and double-side design.
And the thickness has 1oz, 1.5oz, and 2oz.
Normally the good led strip light use Rolled copper +double side PCB design +2OZ.
The is good for heat dissipation and less voltage drop.
4. Check the package
We can check the package if the reel is recycled used or new. The recycling used may be broken and dirty.
5. Check the label
Check the label if the detail is enough led type, led qty in one meter, voltage, wattage, IP rate.
