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 gotten LED bulbs at Goodwill for $1 for a 4-pack. I have those in my front and back porch lights which I keep on 24/7. I haven’t had to replace them for years.
You may have an electrical issue that’s causing them to burn out. Have you had an electrician test the wires?
