TDLR: I have about 10 meters of 22GA coming from the power supply directly to a second LED strip for power injection. The problem is that there’s voltage drop immediately: it starts as yellow and goes into red and then dims into nothing in about 30 LED’s (the color is set as light green). It’s getting power directly from the power supply; how can only so few LED’s be lit up?
Before I spend a whole day trouble shooting or spending money on things, I may not need I was hoping for advice in which direction I should go. The problem is stated in the TDLR. My first strip of LED’s (~2-3 meters) is lighting up just fine. At the end of my first LED strip the data wire joins up with the power injection wire and follows it to the 2nd LED strip where the problem is occurring.
Could the issue be the distance / size of the data wire? The distance / size of the power injection wires? Poor material quality of wires? Poor soldering job / too many soldering jobs (Made a couple of mistakes with length.)? Wago connectors?
Farther fetched idea: Bad power supply?
Power Supply - MEAN WELL LRS-200-5 200W 5V 40 Amp Single Output
Wires - All 22GA
LED’s - WS2812B 5V 60 LED/m
Microcontroller - Esp32
Here’s a diagram.
The green lines here is the first LED strip and the blue is the 2nd LED strip / where the light cuts out. The power injection cable follows the green line and hugs the wall all the way around until it gets to the second strip.
