ELI5. What causes some electronic, LED-based light fixtures (such as an ordinary LED strip or a light bulb) to emit a brief pulse at random, long intervals, when plugged in but turned off?
In: Engineering
You likely have some bad fixtures. There’s nothing inherent to LED fixtures that should make that happen.
Perhaps there’s a bad capacitor that is discharging too quickly and messing with the internal control signals.
If they are properly turned off like house lights then this should not happen. If they are turned off using software rather than a switch then it is possible for long wires to act as an antenna and receive wireless signals which can make fake control signals to turn them on momentarily. I had this as an issue when I was using a light strip that was supposed to respond to music. The long audio cable was picking up random pulses.
