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: https://www.ebay.co.uk/itm/332895172548 ? F 1 Link to comment Share on other sites More sharing options...
Adsibob Posted March 22, 2022 Share Posted March 22, 2022 Just wondering where everybody buys their LED bulbs these days? I'm looking for an online supplier of high quality dimmable LED bulbs in various sizes, all with 2700K to 3000K colour. Link to comment Share on other sites More sharing options...
JohnMo Posted March 22, 2022 Share Posted March 22, 2022 My last ones came from Toolstation, mainly because they give you a life expectancy. Small difference in cost between 40/50k hr life bulb and one that lasts 15k hrs. Link to comment Share on other sites More sharing options...
Marvin Posted March 22, 2022 Share Posted March 22, 2022 We often use the bulbs with a wide angle 110 degrees or so but not widely available. Link to comment Share on other sites More sharing options...

Temp Posted March 22, 2022 Share Posted March 22, 2022 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. Link to comment Share on other sites More sharing options...
Temp Posted March 22, 2022 Share Posted March 22, 2022 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.

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.

Mattg4321 Posted January 7 Share Posted January 7 Integral are generally decent. I’ve used them quite a lot over the years. Even they can’t make a reliable G9 though. Link to comment Share on other sites More sharing options...
