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.
Important: never buy IKEA bulbs (lamps and all the aesthetic part OK, but not the light bulb itself)
I had dozens of those dying one by one in my apartment, I always substituted them with Philips bulbs and they never had issues
