Problem with dimmable LED lights

[Vaud]

I have 4 LED lights in the bathroom installed by a qualified electrician, with a dimming switch.

All worked fine.

Then we get a progressive problem over about 2 weeks - the lights get dimmer from their original brightness, and then go out sequentially, the one closest to the switch first after about 20-30 mins.

But they aren't failing, when you switch off the light, and back on, they come back on (but still at a reduced brightness vs when they were new).

The electrician has replaced the driver once and is investigating, but I thought I'd throw the problem out there... I'm guessing it's possible a brand mismatch.

Thanks all.

To (hopefully) close this out... it looks like it was an issue with the driver; after reprogramming it it has been fine so far.

I'm an electrician and I've still got about 50 12 volt halogen downlights in my house, mostly on dimmers, they are about 7 years old and I've not had to change one transformer yet and maybe 6 lamps in that time. I have no intentions to change them to LED any time soon. Granted they are not on a lot but using dimmers on halogens negates so many problems associated with halogen downlights. Plus LEDs give off a horrible light compared to halogens.

I quite like the white light from the ones we have.

On a side note, they do of course strobe, which you don't get with halogen, and it starts to show as banding in photographs taken indoors. Slightly annoying
