I have two light fixtures outdoors connected to the same light switch. Both of these fixtures are identical and have standard (USA) light bulb sockets. Brand new LED light bulbs were installed in each fixture and all was good. After a few months, one of the bulbs when turned on would always be consistently blinking. Wanting to rule out an issue with the fixture, I connected the bulb to the other fixture as a test and it was flashing in that one as well so I assumed this was just a bad bulb. The bulb was replaced ( same exact brand ) and all was good. Fast forward another few months and the replacement bulb is now constantly blinking when on.
Is this just a coincidence that two different bulbs on the same fixture would start behaving this way or could there be an issue with the fixture that would cause this?
EDIT To answer some questions in the comments:
- The switch is an on/off timer switch
- The fixtures are not fully enclosed ( the bottom is completely open )
- The bulbs are Ecosmart (1004 865 468) and the box does say that they are suitable for wet locations as well as enclosed fixtures and uses only 8.5W
