Skinflint Seeks Free Advice on burnt-out LED Transformer

EdTheNed · Sep 7, 2018

Morning.

The LED light above my bath doesn't work. I yanked all the stuff out the ceiling and found this.

[ElectriciansForums.net] Skinflint Seeks Free Advice on burnt-out LED Transformer

So far, so good. But hark!

I have come to the conclusion that something is wrong with the transformer. Worst case: it may never transform again.

If I just buy another one with the same spec, is it going to do the same thing again? I don't really want to burn my house down, but also don't really want to pay* for professional advice.

Just for further context, here's some stuff that was written on the transformer (a bit curly from the heat, right enough):

Plan is to buy one of these, but why did the old one burn out? Is it standard for LED transformers to melt silently in the ceiling? Is there anything wrong with the setup shown?

Cheers to anyone spending the time to answer my stupid questions instead of having someone pay you to do it.

* Maybe my karma is running out, always asking questions and never giving anything back. Maybe somebody will one day deliberately cause me to electrocute myself through purposely erroneous advice. Until then, thanks everyone! My heroes.

Personally, I'd buy one of these:-

Premium Electronic Lighting Transformer 0w - 50w - https://www.tlc-direct.co.uk/Products/LTYT50.html

And replace the halogen lamp with an LED equivalent. Will save you electricity so you can pay a spark and won't generate as much heat thus reducing the chance of burning your house down.

It looks to me like that transformer was a little too close to the lamp.

i've got a bagfull of them transformers, all ripped out when converting to 240V GU10LEDs. as sparkychick says. go LED. it's 2018, not 1918.

How old were you in 1918 Tel? chuckle

You do realise the OP thinks his light is LED?

Suitably rated gu10 would be the way to go. It will never transform again is a good line it gave me a laugh I might use it in the future lol

If you go LED you'll generally need a driver not a transformer so be careful what you buy.

It was never a transformer in the first place. It was a halogen light switch mode power supply.

was??? it still is.!. it is not dead, just resting, pining for the norwegian fjords.

Exactly. and the burning is because the "transformer" was sitting on top of the lamp.

Do you some sort of degree in pedantry?
The device connected says what it is

it is an Electronic Transformer.
It transforms (ie it changes) the voltage on the primary, to the different voltage on the secondary.

where is it stated that it's for halogen lights. it could be for a train set. CHOO-CHOO.

The label is a lie. There is no such thing as an electronic transformer. A transformer is a device that changes voltage or current by electromagnetic induction. It doesn't change the frequency either like those switch mode supplies.

The Collins dictionary definition of a transformer is

A transformer is a piece of electrical equipment which changes a voltage to a higher or lower voltage.

Which is what the box in the picture does.
Don’t try and say it has to be two windings and an iron core.

If you don’t agree you need complain to the manufacturers of these things. Most of them call them Electronic Transformers.
Or maybe you are such a Luddite that you haven’t caught up with what things are called these days.

PS There’s another idiot that constantly spouts the same drivel about this on another forum. Are you by any chance Winston1 in disguise?
