Dimmer switch buzzing

[Leaxx215]

Hi there.
Hope someone can help.

We have a new light fitting that halogen G4 bulbs.
We put a dimmer switch on from B&q and there is a very loud buzzing coming from the switch. We have taken it off and put a normal switch on.

Does anybody know if we require a certain dimmer or transmitter? For these to work?

Many thanks

What is the total wattage of the G4 lamps?

Are they 12volt lamps? If so, there will be transformer in the fitting, is it dimmer able?

It's a chandelier. It's 20w halogen g4 bulbs.
Says it's dimmable

Thanks

Yes, but HOW MANY 20 watt bulbs???
and
What is the rating of your dimmer, it will be written on the back of it.

We have 8 dimmable gu10 leds and i bought a dimmer from b&q and had the same problem.....ended up just buying a normal switch

Yes I think that's what we are going to have to do. Shame though.

The biggest shame is you have been offered proper help, but you have instead decided you will just replace the dimmer with a normal switch.

It's quite possible the dimmer is not powerful enough for the total wattage, hence why it's essential to know how many 20w bulbs you are driving

So, you possibly had 8x 50w bulbs, and possibly had a 250w dimmer. Seems likely a 400w dimmer would have resolved the issue?

We have 5 x 20watt bulbs and the dinner we tried was a 400w

What is the voltage of the bulbs?

I did ask…..

Great minds think alike...



I thought another person asking the question might get an answer.

 

[Leaxx215]

It's 12v

So you need a dimmer that is capable of driving the electronic transformers that are in your chandelier. You need advice from the manufacturer of the chandelier.

Ok, I'll see if I can find some contact details.
Thought here was worth a try.

Thanks
