The "life extenders" that are sold commercially (a button that is inserted 
in the lamp socket) are diodes. They cause a soft yellow light that is OK 
for outside lighting and they do work. Unfortunately most are poorly made.

If you rectify the AC to DC and put a Capacitor across it you will produce a 
higher voltage, not a lower one!
