ᐅ LED ceiling light connected but not working

Hello,

I installed an LED ceiling light. Previously, there was a halogen lamp that could be dimmed using the switch. Unfortunately, the LED light does not work. Could the problem be the dimmer switch? When I connect the LED ceiling light directly to a regular power cable, it works perfectly!

Thanks for your help

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

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

If it’s that simple, then please share your experience. We had to switch back to halogen because nothing worked with LED…

A few more details:

The packaging usually indicates whether an LED bulb is dimmable.

If it is NOT dimmable and connected to a dimmer, it can damage the LED bulb. So, it’s best to test the bulb without a dimmer first!

However, even if an LED is labeled as dimmable, that does not mean that every dimmer will work!

There are different types:
  • Universal dimmers for resistive loads with 230 V – incandescent bulbs, (line voltage) halogen
  • Dimmers for capacitive loads – for bulbs operating at 12 V, for example, with an electronic transformer
  • Dimmers for inductive loads – also with a transformer but a “classic” one (e.g. toroidal core)
The latter two types can work with dimmable LEDs – but not necessarily. It depends again on the type of LED.
