Most all my LEd purchases have been T10 wedge base. 914/912/168/194 bulb sizes.
Some have failed. Some have just been replaced when I searched for something brighter as the tech progressed.
Now, I Pretty much have the brightness I seek, and more. So PWM dimmers on everything.
Some of the LEDs Whine audibly when dimmed on the PWM when there is not enough other white noise, like from fans.
My latest t10s are my favorite. I've purchased 10 then immediately 10 more. about 5 have failed in 10 months. Too much heat. The receptacles were inhibiting airflow. I was getting 10 for 5$ so no big deal. I've got 10 backups, and when they are done, there will be something brighter and more efficient and perhaps, just as inexpensive.
But that last part could be political.
My experience, is the 5730 LEd chipsets, give the bright white light from the fixtures I was using, that I was seeking long ago, that the 5050's never did.
