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’m going to speculate you have some issues with power delivery. Are you in an older home or get hit with brown/black outs? Could be under or over voltage by enough to burn through them. I have used dollar store bulbs all the way to hue branded bulbs. I might have had one die early from dozens in 2 different properties.
