DeRun use pure gold wire, good conductivity, high brightness, fast heat dissipation and long life. A lot of led diodes in the market use aluminum wire and copper wire, which has poor conductivity, slow heat dissipation and short life.
DeRun use double copper layer PCB, which has good electrical conductivity, good thermal conductivity and good heat dissipation.
Discrimination method: look at the texture (Double layer PCB can not see the circuit board texture on the back; Single layer PCB can clearly see the circuit board texture on the back)
All DeRun standard LED strip lights are CRI>80 at least. We also can do CRI>90 and CRI>95. We can offer test report for all our LED strip lights by our test machine: Integrating sphere machine.
DeRun use 3M adhesive imported from the United States, and has high adhesive strength. It can be firmly stuck and does not fall off no matter how long it is used. Most of the products in the market use inferior glue, which is poorly viscous. After some time of use, it begins to fall off.
