These bulbs are not economical at all because I have to constantly replace them. Saving on electricity does not justify these expensive bulbs burning out in less than a year. The only two that have lasted are in my range hood for light above my stove. Those experience extreme heat and yet they are fine. I have had to replace 2 light fixtures that have permanent LEDs and no replaceable parts too.

    Get the ones with the CE mark as, since 2017, the EU rules for LED Light Bulbs are very strict (for example, models must be tested for min 10k hours of life with at last 95% of the bulbs passing, and 10,000 on-off cycles) and that CE mark means they were tested in accordance with them (unless the mark is fake, obviously).

    Also as others pointed out, you want to make sure the light fixtures you have them in do not trap heat: LED lights emit way less heat that incandescant but if it can’t go anywhere temperatures can get pretty high, plus both the actual LEDs and the components of the power converter at the bottom of the lamp (as the Light Emitting Diodes themselves take DC, ideally with a regulated current, not 110/220V AC) are way more sensitive to temperature than the stuff incandescent lamps are made.

    Beyond this, also note that when it comes to overall quality (rather than merelly efficiency), that converter circuit makes most of the difference and manufacturers competing mostly on price will often use designs for those with significantly lower quality to save a few cents per unit. You might want to consider getting the Dimmable LED Light Bulbs even if you aren’t going to use them with a dimmer simply because in order for it to be Dimmable that conversion circuit needs to have a different, better, design that the cheapest ways of designing it.

    At one point in time, maybe 7 or 8 years ago, I looked into setting up a business to import those things from China, and most samples I got from back then still work (except the ones from the really crap manufacturer, of the rest maybe 1 in 5 failed since then) - this is also why I know all those details about EU LED Light Bulb requirements and certification.

    I’ve also been using LED Light Bulbs since even before that and have had very few failures in almost 10 years of using those things, even though I never buy the branded expensive stuff.

    Last I checked the factory price of a decent 100 lumens LED Filament Light Bulb at the factory in China was around $1 so LED Light bulbs above $/£/€5 are way overpriced.
