If someone does have problems with interference from these converters (or quite a lot of electronics) then the fix might be to put a ferrite bead on the output cable close to the device. Arbitrarily picked eBay example:

Umm, that's a URL? Sorry.

 

I didn't pick the first eBay listing because it showed the cable just running straight through the bead. From what I've been told that's close to useless, you need to wrap the cable round at least once and preferably a few times.

 

I suspect the difference between “good ones” and others will be whether they have a choke of this sort on the output fitted internally.

 

This seems to iwork as well:

I've recently been buying Osram Parathom GU10 LED. Specifically..

 

Bar code 4 058075 609013

7.9W 650 Lumen

2700K

120 degree beam angle

Dimmable version.

 

Over the years I've tried a bunch of cheap dimmable LED and found they flicker horribly when dimmed. Originally thought it was the dimmer and switched to a trailing edge type but this didn't fix the problem I was having. However these Osram bulbs must have a better circuit inside as they don't seem to flicker at all. 

 

The dimming isn't quite as linear as a halogen but they can be turned right down unlike some LED that have a high minimum below which they turn off.

 

On full it's bright, almost too bright. Anything over 450 Lumens works for me.

 

Has a 5 year warranty according to the box.

Just a heads up on the A to G energy rating...

 

The EU changed how the scale works so that many LED now E, F and G rated. 

 

Don't let a G rating put you off. The Osram I mentioned above are G rated but dissipate 7.9W compared to the 50W Halogen they replaced and are brighter.

Some of our LEDs have failed or started flashing. Probably 5% 

 

Crompton have been very good at replacing them under-warrenty 

@readiescards how have your Crompton LED bulbs faired since? I’m looking for a particular e14 bulb, and my choices appear to be Crompton, Integral or a bunch of unbranded options. I went for an unbranded option previously, but that bulb has a quiet buzz which is somewhat annoying and also suggests to me it’s not as efficient as it could be.
