I have 10 separate LED strips behind a dropped ceiling feature. Each seems to have its own driver and none appear to be connected to each other except via the same power source and switch. Two that aren't even adjacent to each other will suddenly begin to flicker simultaneously after many hours. Switching the lights off and back on stops the flickering for awhile but the same two sets simultaneously start flickering again eventually. Any ideas how to stop this problem?

The input voltage to the driver must be the same as the voltage required by the driver. If not, the voltage variation can cause flicker or flashing. The driver should have a sticker or imprint showing the voltage requirements. Also, if you have 10 connected to the same power source it may be causing the voltage to drop just enough to cause the flickering. Use a meter to check the voltage at the point just before entering the drivers. If the voltage is correct, the drivers may be going out. I do a lot of work for hotels and electronics tend to go out at the same time if they were installed at the same time.
