I got a 60W Equliv. LED bulb in a fixture that flickers all the time.
Its not very old. It does produce enough light but gets annoying after
awhile. They only cost a buck or two, so i'll just replace it, but I
wonder what is causing the flicker?

My guess is a cheap electrolytic in the rectifier, but I have never
really seen a schematic for how they are wired.

Was the bulb holder designed for an LED or was it originally for a
filament bulb? Some of the smaller LEDs, such as G9, can overheat in a
non-ventilated holder. This can show as flickering; usually it's the
power control chip rather than the LEDs themselves which goes first. The
bulb will eventually fail.
