When we use the LED strip lights, we noticed that if we connect the long cable to the strip light, the brightness will be less than using a short cable. That is because the longer the cable is, the more voltage drops the strip light.
So if we need a long cable for the strip light, we need to use a thick copper cable then avoid the strip light voltage drop.
You can use a gauge chart to figure out the right cable thickness for your setup. The gauge chart allows you to see the right thickness for your LED strip’s power consumption.
