Tell me what you are using. I'm lucky to get two years out of them. And for some reason with outdoor fixtures, it's almost like the shell or tip don't make good contact when you screw them in. They flicker as you wiggle/twist them, even dim. I clean the socket and center contact thinking this is because of corrosion but no good. I wind up using a different brand. Incandescent works fine and LED works fine in an indoor lamp. And this isn't in just one fixture, it's several different ones.
These things were supposed to be the greatest thing since sliced bread but they are nothing but trouble.
