LED ceiling lamp connected. But it does not work

Yes, 230 volts. The LED lamp is already dimmable by remote control...

Yes, then just the switch insert and that’s it.

Yes, then just change the switch insert and that's it.

If it's that simple, then report back. We also had to switch back to halogen because nothing worked with LED...

A few more infos:

The packaging usually indicates whether an LED bulb is dimmable.

If it is NOT dimmable and connected to a dimmer can cause the LED to break. So it’s best to test the bulb without a dimmer again!

But even if you have an LED that is marked as dimmable, that doesn’t mean every dimmer works!

There are different types:

[*]Universal dimmers for "ohmic" loads with 230v - incandescent bulbs, (high-voltage) halogen
[*]Dimmers for capacitive loads - for bulbs that run on 12v etc. and have an electronic transformer
[*]Dimmers for inductive loads - also with a transformer but a "classic" one (toroidal core etc)

The last two can work with dimmable LEDs - but don’t have to. It depends again on the type of LED.
