I'd like to install 5 dimmable led bulbs.

I'm trying to find how to connect them. But I can't get a clear answer. I can get information of the benefits of wiring leds in series/parallel but none of them mention a dimmer.

The question is if I should wire them in series or in parallel? And does this affect what kind of dimmer I need?

Those are light bulbs.

You must connect them in parallel just like you would connect other 240V light bulbs in parallel.

You must use a dimmer intended for LED lights.

If you are referring to light bulbs which will be fitted to the mains they need to be in parallel.

Also, if one of the LEDs were to go, in parallel the rest would still operate hence why most mains equipment are fitted that way.

I hope that helps.

  • The OP is referring to LED light bulbs, not LEDs (the individual components). – brhans Apr 22 '19 at 14:03
  • Ah ok. Then they have to be parallel. He /she didn't specify so I was unsure. 🙂 – Caspar P Apr 22 '19 at 14:05
  • Ok edited. I didn't see that link either. - sorry – Caspar P Apr 22 '19 at 14:08

Mains power is a constant-voltage system. As such, everything is wired in parallel.

Constant-current power is not unheard-of in mains wiring, however it is notoriously dangerous and as such, is used in extreme specialty applications and requires special handling - e.g. shorting the output of CC transformers to keep them from trying to create infinite voltage. Transformers don't have crowbar/limiting circuits like electronic supplies do.

Series would be a really weird thing to do, and you would need precautions against a device malfunctioning, or worse, the next occupant doing something dangerously moronic because he didn't understand your setup -- the latter reason is why "weird setups that require knowledge to use safely" are prohibited.
