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 am using GE daylight and they say 13 year guarantee on the box. They are at least 2 times as much money as all the imported ones. I have used Walmart and similar and they never last. I tried OSRAM made in Germany and they sucked for brightness. All my lights are not enclosed. They are all open air fixtures with lamp shades and my ceiling fans all have 4 candelabra style. The longest I have gotten any to last is 3 years.
GE is terrible. Use Phillips or Cree. Also turning them on and off often does shorten the lifespan. I’ve had some running 24/7 for maybe 8 years at this point and they’re still going strong.
