Testing the Specs of 12V Resistor Based WS2811 Pixels (Updated)

[Updated 6/8/21] With an additional section covering the analysis of running all 300 pixels.

In this video, I test the specs of recently purchased 12V resistor based WS2811 pixels. I test the max power used by a pixel and compare it to previously tested 12V regulated WS2811 pixels. I perform 2 test methods to determine the effective electrical wiring gauge of the pixels, and I test running 300 resistor based pixels without any sort of power injection or power balancing.
