Different production batches will cause this phenomenon, and low light brightness also can lead to this. Manual mode no problem the light has no issues. If you wanna the same colors you can set higher the light percentage.
I do not like it. If I buy two lamps, I expect them to be identical. I'm not going to set anything up manually. Please tell me what I should do to make the lamps glow the same on automatic settings.Should I replace the PCB? Which ID is older and which is younger?
Because of the dynamic change of the alternating current, it has a current difference.
The current difference is superimposed several times on the led beads. Even if the current difference is small, the data will become very large after the superposition, so the color is different.
The smaller the intensity, the more pronounced the difference.
