Some older wiring and devices can interact poorly and cause fluctuating voltages. The more stable the voltage, the less wear on the components and vice versa.
If you were to lower the voltage would it still cause extra wear? Like is it the fluctuation itself that causes the wear or is the the 'higher than expected voltage' during peaks of the fluctuating?
I know undervolting can make some electronics, including lightbulbs last longer, but I don't know if that would countermand the extra wear from the changing voltage.
I haven't explored LEDs too much, but have an education related to transistors. Because they are diodes, significant overvolting will degrade the diode itself and if it were to happen often enough could damage the junction to the point of no longer working. Fluctuating voltage could damage other parts of the device, but I'd guess overvolting is the bigger danger
