My Ikea bulbs have been working for almost 10 years. Only recently one started flickering.
Going for $1 bulbs is not planned obsolescence, you know the parts inside have John's Goodenough QA.
Bought a chinese bulb as a temporal fix, lasted 4 days  :) :scared:

Agreed.  Buy cheap, buy twice... one issue will be a lot of people don't comprehend this and do buy cheap LED bulbs that end in landfill.
Personally I've had only one LED bulb fail on me and that was a novelty smart bulb a friend gifted me.  Every other bulb has been rock solid.

Especially the IKEA bulbs that DavidAlfa mentions are not really an example for "Buy cheap, buy twice".
Granted, my sample size is tiny, but my experience with IKEA LED bulbs is excellent, given their price. I have two E14 base bulbs running now for at least 5 years, i don't remember when i bought them. They were like 3 Euro for 2 or something like that. Granted: They are low wattage, and the fixture i use them in is open and well ventilated.
BigClive also only had good things to tell about IKEA USB power supplies that are also very cheap for what they are.
And IKEA rechargeable batteries also seem to rival Eneloops.

I sound like an IKEA shill :D But i really only mostly heard good things about them with electronics.

Buying low wattage helps a lot.

If everyone ignores the brightest LEDs and buys the dimmer ones because they'll last longer, doesn't that just lower the bar and then producers will churn out cheaper short-lasting dim lights instead?

A lot of the problem is the legacy form factor. It's not well suited for LEDs of the same power as incandesces.

Very few I actually believe the claim due to the case temp on the thermal camera.

If those are Ac led lamps you should know it is BS.
Have you ever seen a manufacturer making elektrolytic capacitors with a guaranteed lifespan of 50 years ?

If you want to sort the BS from the decent ones, look at the packaging, it should not only state an expected amount of hours but also an amount of on/off cycles, which is exactly where the elektrolytic capacitor comes in.

For dc/dc led bulbs 40000 hours if used mlcc capacitors or those solid elektrolytes should be feasible. If you want long lifetime you need a decent led driver. A decent one will already cost you aroud €20 minimum, the professional grade ones will cost multiple times that and are sold forvroadways, tunnels, swimming pools, pro applications where changing the bulb in manhours and equipment cost more than the driver/bulb  ;)

If you want to argue about low cost low lifetime garbage, talk to your neighbours and educate them. Also tell them the capitalist way of living has its negative sides where manufacturers would like to make profits and sell something, which is pretty hard if the other side of the world practically gives their low lifespan electronic garbage almost away for free  ;)
