Which replacement transformer to buy?

[macbun]

Hello any advice please.
I need to get a new transformer for a ceiling light. I attach a picture of the old one. I cant find exactly the same one on line to buy and I don't know anything about electrics to see if the alternatives out there would do the same job. Can anyone with sparky knowledge point me in the right direction to a similar transformer which would be safe to do the same job. thank you in advance

search google for eaglerise set250ck

plenty of places will be found

set250ck is the important part number

It is 12 volt at 80 - 250 watt, also called VA so 80 - 250 VA. The problem is physical size, but today we tend to aim for LED lighting, and to find LED's of 80 watt or more is going to be a problem.

I will assume quartz halogen at the moment, and likely you will want to convert to LED.

So with original you need more than 80 watt but less than 250 watt, a G4 bulb was typically 20 watt, so 5 to 12 bulbs on that transformer, but a LED is likely 2.6 watt, so it would need around 30 bulbs to work, the problem is you look at an advert for "G4 LED Reflector Lamp 900 mW(10W)" and think it's a 10 watt bulb, but read further and you find it is actually 0.9 watt, not very helpful.

There are now electronic transformers which start at 0, but not sure about that shape.

You would probably do better to convert to mains voltage LED lighting, which is simpler, runs cooler, uses less electricity, lasts longer, and is less troublesome.

IMO low-voltage halogens are a dead end.

Post pictures of your lamp(s) please.

Thanks to all who replied. I am still confused, will i be able to get like for like or is the view that i upgrade the bulbs and then get a slighly differant transformer?
thanks in advance...heres pics of the bulbs as asked for JohnD

Is it a sort of chandelier?

Changing to LED lamps will change the appearance of the fitting The lamps you have shine light is all directions and thus the glass globes are evenly lit.

LED lamps will not provide the same spread of light and thus the glass globes will not be evenly lit

I would be inclined to investigate automotive replacement LED's and add a mains to 12v DC PSU.

If... and this is a important consideration.... you are capable to do some wiring to a safe and competent standard then____

I think those are G4 bulbs so change them to these 12V G4 LED versions (warm white, 1.2W).

Amazon.co.uk

And suggest they are all powered by one constant 12V LED driver ( I presume you have 5 lights, so you need at least 5 lights x 1.2W = greater than 6W.

NOTE Ericmark comments below that good chance these LED bulbs will not fit as larger than G4.

Looking at 12 volt switched mode DC at 1 amp cheap enough at £5 but size is

Item dimensions L x W x H

9 x 4 x 2 centimetres

Will it physically fit?

Ericmark,
Very good point.
Was looking on phone so missed how small lamp holders are.
LED G4 are going to always be bigger than illuminecent G4 and so good chance not going to fit.

I'd be thinking about buying a new lighting fitting.

 

[ericmark]

I was thinking about transformer size, but bulb size also important of course, I have some G9 lamps, basic the 230 volt version of the G4, and the LED lamps which allowed you to fit the covers on the bulbs we had problems with not switching off and a shimmer when on, we found larger bulbs that worked you can see the two bulbs, so covers would not fit, lucky wife likes what they look like, but the whole assembly looks very different with LED, the covers are really to stop white hot bits landing on the carpet if the bulb blows, so not needed with LED, but the whole lamp looks very different.

The tiny version, top right, appears to be what I swapped all of my cars interior lighting over to, all six of them. They are much brighter and whiter than the original filament lighting, as well as less power hungry. Which was why I suggested looking at automotive replacement LED's.

 

[ericmark]

The automotive LED needs smooth DC, 10 - 30 volt, and are more expensive to standard house hold types.
