Removing Transformer From Halogen Light Fitting For LEDS?

[LENNYLENNY16]

Hi all,

Great forum with lots of advice read and greatly received over the years!

I have a question here that I am hopeful somebody here can assist.

We have 6 x decorative light fittings that all currently take 5 x G9 Halogen bulbs per fitting. And we also have another 5 decorative light fittings that each take 6 x G4 halogen bulbs per fitting.

We really like the fittings and don't really want to change them if possible. We ideally want to swap all of the halogen bulbs for LEDs, but when we have added the LEDs they flicker a lot and there is a loud humming noise which I presume is the internal transformer.

The question is, can the current transformer, intended for halogen bulbs, simply be removed? And the fitting then wired directly to the lighting circuit cabling and LEDs with internal drivers installed? Or if the LEDs don't have an internal driver, can the transformer be replaced like-for-like with a separate LED driver?

I've added the images of the current transformer and the wiring from one of the fittings here as an example where I have already removed the transformer.

Thanks in advance for any help or advice on this - greatly appreciated.

Use halogen lamps or swap the fitting. You certainly can't wire it direct to the mains, the construction of the fitting is not designed for that to be carried out safely. You may be able to swap the transformer for an LED compatible one there are a few suppliers of round led power supplies designed to go into the base of fittings such as these. I would generally recommend replacing the light with a properly constructed one though.

G9 are 230v mains rated lamps so there shouldn't be a transformer to cause a buzz!

Maybe on the G4 fittings though?

Picture 3 says it's an electronic transformer so there will not be any buzz

The components inside can make noise when being run outside their specified operating conditions, especially wound components.

The transformer is labeled the secondary voltage is 12v.

The OP says there is a loud humming (my word buzz) noise !!!

The transformer is labeled the secondary voltage is 12v.

I know, but don't think Ive ever seen G9 other than 230V, have you?

The OP has only made 2 posts, the last one being 4 months ago, basically asking the same question.

Thanks Freddo.

When you say an LED compatible transformer, is this the same as an LED driver?

This certainly may be an option for the fittings with the small G4 2 pin bulbs.

However, am I right in saying that the G9 bulbs have built in drivers? If so, would these still need a separate driver in the fitting would you suggest?

Thanks again for your help.

On the G9 bulb fittings, where I have replaced the halogen with the LED G9s I am definitely getting a buzzing noise from a couple of the fittings.

I will take the fitting down to confirm the existence of a transformer or not.

If not then I'll report back for any further advice or suggestions that you may be able to share.

Thank you again for your help with this and your reply; greatly appreciated.
