I think LEDs will never really succeed in replacing the standard screw in bulb. LEDs are more liekly to take off when a paradigm shift in lighting occurs and fixtures have the voltage and current control built in with plug-in LED modules.

There are some web sites that show how to take one apart and repair the electronics since that is what typically fails, not the bulb itself. Not sure if I would want to do that on something that could start a fire in my house. Might even void the UL rating to dissassemble and repair.
