You likely have an issue with your wiring. LED bulbs last much longer on average on a a good circuit - but they are less tolerant of spikes and drops in voltages, thus circuit, switch, wiring quality comes into play. Would be much easier instead of embedding an AC/DC converter inside each bulb that we now get standard 12V DC for lighting throughout homes - That would centralize the voltage sensitivity and allow larger circuits / capacitors to regulate this.
