I have several LED light panels and after about 3 years, they are beginning to flicker and go out. About half of them within a few months of each other.
They are 15w panels and the drivers are also dimmers. The LED driver wires directly to 110v main power and there is a standard electrical dimmer switch on the wall that adjusts (presumably) the voltage going to the drivers.
I have taken apart the driver and there is a 10uf 400v capacitor that is bulging out the top and has some burns near the base.
I would like to replace the capacitors, but I am wondering if a larger voltage or capacitance will work better and give them a longer life?
I assume I can put a larger voltage rating, but I am not clear on how increasing or decreasing the capacitance rating would affect efficiency and lifetime of the overall system.
