We have a multistory apartment building where the hallway lights were switched from CFLs to LEDs. These lights are continuously on.
Originally the LEDs were SATCO 15W bulbs. These lasted about a year before beginning to flash/blink/flicker.
They have been replaced with FEIT Electric 10W bulbs. These now last less than 30 days before flickering.
The flashing goes at maybe 5Hz for a minute before going solid again before eventually dying.
There is no dimmer switch on the circuit (common cause of LED flicker). Am not sure what to check. Is there not enough resistance in the circuit? (The 10W bulbs don’t last as long as the 15W bulbs)

You should check the packaging on the LED lamps. There are many that say not to use the LED bulbs inside enclosed lamp fixtures. The electronics built inside the base of LED bulbs that converts the AC mains voltage to that required for operation of the LEDs is often times not very tolerant of elevated temperatures. Even a low power 10W or 15W bulb inside a globe could build up heat to raise the temperature too much for the bulbs.
I highly suspect that there is a range of LED bulb quality that may very well make some more sensitive than others.
One thing you could try as an experiment would be to put new bulbs in a couple of the fixtures and leave the globes off for a few weeks to see if the last longer.
