Radio shack sells small conductive discs that attach to the bottom of 120v incandescent light bulbs. They claim that these discs will extend the life of your light bulbs up to 100 times. Does anybody know how these work? My theory was that a rectifier in the base would prevent the reversal of the magnetic field in the bulb due to the AC polarity change. This might reduce fatigue on the filament. (Just a guess, don't flame me for being stupid!) ******************************************************************************* ** Hugh L.
