LED's not as described on Ebay

Cookieie

Its definitely worth trying for a refund/replacement of product as the ones supplied haven't lived up to the hours stated in the advert.

That's interesting. If I read it correctly, I can only conclude that the OP and I have been unlucky in our experiences of LEDs. Are you aware of any available distributions of LED failures? Like a normal distribution or whether skewed one way or the other (although I presume it varies from manufacturer to manufacturer)?

As alluded to earlier, what also matters is whether you're using the right type of LED bulb for the circuit. Just because the bulb will fit in the holder doesn't mean it is suitable for the circuit ... for example circuits with dimmer switches as referenced earlier.

We’ve replaced most of the bulbs in our home with LED bulbs, after a few failures at the beginning from cheap bulbs bought off eBay we came across this video https://m.youtube.com/watch?v=p_DB-0E9k3A

Needless to say since then we have opted to pay a bit more for safer bulbs with proper shielding and they are all still going strong with none of them yet needing replacing at between 4 months and 2 years use. Of. Purse only time will tell how well they last.

Another note is that even if the LED's themselves can last up to 50,000 hours, the extremely low cost components that make up the crude power conditioning circuits inside the cheaper bulbs most likely will not!

Edit: Fosterdog's post kind of beat me to it. That's what I get for popping out for lunch between writing and posting!

That's what I was hoping to find when I did the search that found the page that I linked to, but I didn't spot one - I think I have seen such a graph previously so I would think that it does exist.

I'm hopeless at electrics I'm afraid! I simply took the old halogen bulb to a specialist lighting shop(*) and asked for two replacements and the LEDs were what I was offered.


The floor lamps simply plug into two (different) wall sockets. The main ceiling light in the room used to have a dimmer switch but that was replaced by a standard sort of rocker switch ten years ago. Could that be significant re early failure?


(*) The specialist lighting shop is very good and in my experience their customer service is excellent and the staff very knowledgeable. I'd be disappointed if what they sold me wasn't suitable for it's intended use(?).

Were you replacing 12v Halogen/dimmable bulbs? The drivers are not directly compatible and this may cause premature failure

In my case I was replacing halogen bulbs (not dimmable though). The lamps are plugged into the mains so I'm assuming they're 240V rather than 12V(?).

Some halogen bulbs ran at 240v, some at 12v (with a transformer in the roof space somewhere), so I don't know which you have, and if there is a transformer in the circuit (you would never know from the switch end BTW) then that may be the issue. Of course it may be a rubbish batch of bulbs too, but without checking I cannot tell which, but it seems an especially rotten run of luck which is why I wonder if there's a bigger story.
