This old chestnut again .

[FatAlan]

Customer with house full of MR16 halogens. Anyone recommend an LED replacement that will work off these?

 

[telectrix]

no.you need to replace the transformers with drivers or use 230V GU10s direct onto the 240V feed.

 

[FatAlan]

Cheers Tel ... are there really no LEDs that work of those transformers?

The Philips ones I have found usually work
Philips LED 12V MR16 Lamp 7W Warm White 621lm - https://www.toolstation.com/philips-led-12v-mr16-lamp/p67099

There aren't any that will work well or not suffer as a result of being powered by AC.

The simple problem is that LEDs work on DC and that power supply outputs AC

And you will take on the warranty for the compatibility between the old and the new, if you do find something.

I would quote to replace the lot with something new.

 

[telectrix]

not only that, but the transformers have a min. load of 20Watts.

 

[FatAlan]

Cheers folks. Gives me some more ammo to appraise the client .

 

[telectrix]

you could perhaps run 5/6 LEDs off 1 Tx. but that's more difficult than converting to 240V GU10s.

Will advise to replace with 230v versions but if I can find an LED that works that will do for time being minus any guarantees. Speculate to accumulate
Already had a customer who wanted to light fittings replaced come back to me for a shed power up.
From little low voltage LED bulbs grow big bad shed wire ups!

Remove transformers , convert to mains 240v (I did this at my house) purchased 30 x mains LED lamps from screwfix 3.5 years ago and have only had one fail so far...

As above Fat Alan, within the existing downlights, replace the MR16 lamp holder with a GU10 lamp holder, disconnect transformer and terminate into suitable enclosure. Remember to offer dimmable led lamps for future use.
