ᐅ Why Are the LED Lights Flashing in a New Build?

Hello,

I have switched to LED lamps in our new build. Now I noticed that some of them flicker, while others glow very dimly even when the switch is OFF.
Is there anything that can be done about this?
Above all, is this normal in a NEW BUILD?

Thank you in advance...

No, that is definitely not normal. I suspect the components are either incorrect or improperly connected.

The lights themselves are definitely connected correctly.
According to the electrician who did the installation here, this is normal, which I find hard to believe...

Well, I have soldered several LEDs myself in my life, and they never flickered unless the overall supply voltage was too low, or I had a loose connection.

I can't imagine that industrially manufactured LED bulbs would flicker or dim unless that is intentionally designed.

Hello,

I have noticed the same issue here as well, but only with "cheap" LEDs and in two-way switch circuits. There is an explanation for this – I believe it has to do with some kind of standby current.

I replaced the no-name LEDs with Ph...ps (also very affordable on the marketplace) – and it worked.

Regards...

I replaced the no-name LEDs with reputable brand LEDs (also very affordable on auction sites)—and the problem disappeared.

In two-way and push-button switch circuits, the lamp wire runs parallel to the live wire inside the cable. This causes voltage to be induced in the lamp wire (when the switch is off). This small voltage/power is enough to make the LED flicker or glow dimly. Brand-name bulbs include a component that prevents this from happening.
