I give up. Totally not getting my point across.

Well I don't know what to say either, my light fitting is not a super expensive thing but it has been correctly fitted and does not have any loose wires.

The dimmed ones are never at full brightness.

Now please answer my question, are you sure that all the bulbs you have fitted for customers haven't failed a few months down the line?

Really? Did you check that again, today? Did you originally tighten the connections, have a cuppa, then re-tighten? Copper wire "eases" under compression from the screw - even over 15 mins. Bet if you check now you could give em a little nip up.....

Yet the ones that have failed are - suggest nothing to you?

I can't be 100% certain, but I register all the bulbs for the extended warranty and the customers are told this - if it fails within the period they come back via me and I'll get it swapped at no cost to them. This makes me confident of what I'm seeing from the field population of product from my installs. So far just 3 GU10 downlights failed. If I was getting the proportion of failures that you suggest then I'd be getting some real stick from unhappy customers. We're not talking 1 or 2 lights per install - some might be 25 or 30 fittings/bulbs - all gone in at same time so similarly aged. I looked back over my order history - nearly 430 units, mainly GU10/MR16 downlight bulbs, some E14 candles.

I'm not convinced there's nothing more to this, maybe even just using inappropriate product. There's a causal mechanism here somewhere but you're just content to blame the bulbs.... Ergo, I'm probably wasting my time try to learn anything from you - albeit it would be to our mutual benefit.

A bad batch of lamps is a causal element.

I agree there are other possibilities, but you cannot discount lamps.

I agree, also, the the OP should check all his connections carefully.

No I checked them a while ago. I’m aware that copper eases, I’m also aware that it can break.
As a professional electrician I doubt that you will spare the time to wait 15mins and check the tightness of wires

It suggests to me that the poor quality circuitry fails more when they are at full brightness. It’s also worth noting that the ceiling light is turned on and off many times during the day where the dimmed standard lamp is on a timer just for the evening.

I’d imagine that many of your customers wouldn’t bother to tell you if a few went wrong. Plus you use a lot of low voltage bulbs, these are probably more reliable

I really appreciate your help but we would get along so much better if you tried a bit nicer tone, I’m not an idiot and I don’t appreciate the tone of some of your replies. I’m convinced the bulbs I bought are not good quality, when I need some more I will buy them from here

I honestly think you just want an argument - blinkered thinking is my opinion (I'm allowed one). I was hoping there'd be a dialogue but you seem to insist my experience (measurably more than yours in this respect) is apparently worthless - to fit your agenda that the product is !!!!. Of course it couldn't possibly have anything to do with picking the right product for the job, or how you're using it, as you are <apparently>an expert...

I never fit dimmables unless they're needed, due to the nature of the product (I'm sure that's your mistake, but you seem unwilling to help me prove that - wonder why?) and no, most of my installs aren't low voltage MR16 but 240V GU10s as they don't need a transformer....

Whatever, I'm outta here now. I'm married, I can get enough grief at home, don't need it on here too. :rotfl:

Forget I tried to be of any help whatsoever, I won't make that mistake again. :mad:

I'm sure buying dimmables from elstimpo's site (yes, I know who's site it is) won't be any different if you use them as you have been.

Buy away - but don't come crying on here when they fail too...

There's no way I came it for an argument but I don't appreciate being talked to like I'm an idiot.

There's also no way I can help you prove the problem is down to using dimmable bulbs. As I said earlier some companies only sell dimmable versions.

Although I'm not an electrician I know a lot about manufacturing, let's hope LED hut haven't tried to save a few pence by fitting inferior cheaper components

Another one failed today

Got tempted to shed a bit of blood and open up a dead one and it had a swollen capacitor.

forgotmyname

Cheap branded ones or worse unbranded?

Is the main cap a 400v one?

There's a 400 volt cylindrical one next to it, but this is an unmarked brown rectangular one.
