which transformer

[rhinosaw]

Hi

I have a table light using 3 G4 halogen 10w. The dimmer switch has packed up and I assume there is a transformer built into this.
I don't want to replace the dimmer switch but which transformer should I get, could I get one that is built into the plug? Thanks

You need a 12 volt minimum 30 watt transformer and you won't get one that size built into a plug.
You could replace the G4s with LED versions and use a much lower rated transformer or DC power supply, probably around 8 watts, which you might find built into a plug.

What voltage are these lamps ?

If they are 240 volt then you will not need a transformer for them.

G4 lamps are usually 12 volt. Never seen a 240 volt one.

Thanks for your replies, they are 12v, I tried without the transformer and the bulb blew

No, me neither

Did you think it might work, somehow?

I looked for some G4 230V LED's to replace some G4 230V halogens and purchased from that exact advert.






Guess what?







they are 12V










and











so are the second delivery after complaining.

That was before I realised 12v and transformer was involved ttc.

If you are getting replacements at no extra cost (i.e. not having to pay return postage), I'd be tempted to keep on and on doing it until they sit up and take notice.

Interestingly someone has given them a 5* review, so either he wanted 12V and didn't read the advert properly, or he got 230V ones.

I wonder where on earth, and by what route, they are coming from - it is, after all, still November! ....

China, and a slow one.

Mine arrived quickly (several days only) and the second set took about 10 days.

Oh and they flicker well (100Hz) on ac but dc is fine.
