How do with people deal with LED bulbs that don't last 25,000 hours (or 25 years?) When they fail after 2 - 3 years and any receipt has long gone to recycling how do you proceed? I'm getting fed up with taking it on the chin and binning them with a C'est la vie approach.

I have the strong feeling that the 25,000 hours “garantee” is only valid for the led itself and not for the electronics “in front of it” and necessary to let it emit light. 😉

Never seen a bulb guaranteed for 25000 hours or 25 years. They're usually warranted for 2 years. The life expectancy, in hours, isn't part of the guarantee.

Some folk seem to have more reliability problems than others, and I suspect this may be down to local problems such as spikes and over-voltages on their mains supply. I don't buy anything special or keep records, but so far my low-energy lamps are at least as reliable as filament types and fluorescents.

Mains spikes can be generated in the home by fridge/freezers, washing machines, and central heating systems. And machine tools...

If trouble is expected, keep the receipts!

Try keeping them on permanently, in a temperature controlled room. Report back in 25 years. I may not be around for the update.

I like the filament ones and have bought these from several places. Most have lasted well, none have failed completely but a few started flickering. Some which were bought via Amazon I did manage to get replaced, others I tried but found that the company had phoenixed in spite of having the same trading name and would not honour previous guarantees. Good news was that they all lasted long enough to save money vs incandescent.

If you don’t have the warranty and the receipt, you have no hope. Learn from it.

The receipt (of items I buy) are stapled to the instructions/warranty, and the whole is stored in a ring binder. Best one can do, I reckon, and is neither rocket science nor difficult. I may well eventually need my house deeds, if I wish to sell my house - what would you do with those?

[Thread drift] Perhaps depends when you last moved, but actual paper deeds are obsolete now, surely? All you need is the reference to the entry on the Land Registry, as that poor chap who was defrauded of his unnoccupied house while living away found out.

Our "back" room in the house is dark so we have tried 3 x 60W incandescents (not really bright enough), 3 x CFLs (reasonable brightness but for some reason very shortlived) and 3 x 15W LED's possibly made by Bell.These gave a really bright light, but eventually started flickering on & off. Replaced under warranty. Eventually the shop closed down so we went elsewhere and found another local shop selling Crompton 15W LED lamps. These are working satisfactorily.

The (possibly) Bell lamps had I think, a 5 year warranty. The Crompton's have a 3 year warranty - not that it's much use as the shop has gone out of business, a casualty of the high street demise. Fortunately, I did buy a spare lamp!

Son in law obtained some LED lamps, for me, ,for use in a reading lamp and the workshop, direct from China.

The ES ones in nthe lamp started to flicker (Presumably half of the full wave rectifier had failed )

The GU22 ones, in an GU22 / BC adaptor are still functioning several years on, despite being used for shorter periods and being switched on more frequently.

The more recently installed GLS LED lamps, in the house, (bought from various supermarkets ) seem to be functioning quite well.

Have recently installed 13 watt ones, in addition to the 9 watt ones. The light seems to be bright, possibly because of a higher colour temperature.

The idea is that in view of the huge rise in electricity and standing charges, the capital cost will be recouped by the lower current consumption, and long life.

The house is almost all LEDs, now, only one or two CFLs still in place. (Wish that I had not stock piled them as replacement for conventional filament lamps! )

Time will tell!

Thanks for the very interesting posts. I am virtually all LED now but what a huge box of spare bulbs I now have. Four different bases, I don't know how many shapes and all the different wattages (let alone Lumens and temperature!) Life used to be so much simpler. I've just had my latest communication from Octopus (I was switched from Avro) and was staggered to find that Electric supplied KWhrs are now FIVE times the cost of Gas supplied ones. I'm so glad that I've converted to LEDs notwithstanding all the hassle.

I’ve now given up buying LED lamps for the overhead lighting in our lounge. Trying to buy a cool white LED lamp with a light output similar to a 100W GLS isn’t easy it seems and the ones I’ve tried have only lasted about 6 months. I’ve wasted a lot of money and ended up with at least six lamps going into the bin. LED may be cheaper to run but buying them and binning them is most definitely not cost effective.

They really do not like heat and overheat easily. It is all down to the light fitting, plenty of ventilation is needed.

Also, to make things worse the cheaper or extra brightness ones drive the LEDs hard which shorten their life.

Google "Dubai Lamp" then next time you visit your Super Yacht in Dubi pick some up.

if you can accept 30W 600mmx600mm panels these + the driver can be fixed to a flat ceiling with a 50mm deep box-surround - these give considerably more light than a 150W old style light bulb - they also last for considerably longer - one in my front room here in IoM has run so far over 10 years (that in my UK house just a miserable 4 years - but you need warm colour as cool white which works well in my workshop cellar will be too unpleasant.

Now you've got me started! The number of different bases is ridiculous, and some humorist in my local Cloud-9 Superstore mixes them up on the shelf!

I don't mind special bases that stop me plugging in the wrong lamp, but providing the exactly the same lamp in multiple different base types is surely malicious. Bring back the birch...

I have been looking for a couple of E10 (10mm dia) Eddison based 240volt 5watt bulbs. Tried all the local hardware / DIY stores local to me (France). Nothing remotely like it except 6v torch bulbs. These bulbs are used on ancient EDF electricity supply contracts which indicate the cost rate of tomorrows electricity (Cheap or expensive).

Finally went on the internet and found a bag of 4 LED lamps E10 Eddison based 240volt for less than 5€ delivered in 48 hours. If they last as long as advertised, am a pleased customer.

Have you got a link, or manufacturer, or anything to get me to them?.

On the general LED bulb issue, the base which contains the electronics gets hot on most of the ones I've used. This is probably why the electronics fails. If I could get more organised I'd take a failed one apart, work out where to drill some holes and let some air in. All my failed ones have had serviceable LEDs, I did once consider trying to make a current driver, but life is too short

The panels are the standard panels used in open plan offices and available from many suppliers - look for your nearest Electrical suppliers eg TLC, City Electrical or Rexal - those on the IoM were made by JCC, those in UK from TLC but most now seem to offer the fitting.
Basically there is enough area in the metal rim and back of the light panel to act as a heat sink.
The base in the LED bulbs is too small and the fitting generally too constrained to allow good heat dissipation.

Such panels are usually used in suspended ceilings? If so then there would be a void above the back of the panel as additional cooling. How are they used if set against a plasterboard ceiling? Attached directly or some sort of enclosure?

can be fixed with small metal brackets (after all we are supposed to be engineers) but this requires the drivers to be remote or as stated "a 50mm deep box-surround " which allows the driver to sit on top of the panel and doesn't need any change to the wiring - a dimmer will be essential for domestic use.
