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.
I’ve only had one led light bulb fail so far despite being an early adopter. And it failed by starting to flicker occasionally, not burn out. So the rest have lasted almost 20 years now.
Might be time to look into what you are feeding them. Check if your power is regular.
