We have that many multi-bulb light fittings in the house that a monthly ritual now is buying a bagful of replacements, particularly in winter.
Has anyone had any success dropping the voltage say 5-10% to extend the life?
I've tried using higher wattage lamps with a diode in series, but the flicker is intolerable. The only other "lossless" ideas I have is either a series 330uF capacitor or equivalent inductor, but they would need to be rated at than 2 Amps to be sure.
I can do the maths, but wondered if anyone had tried this in practice - whats the chance of a catastrophic failure causing a fire at some point in the future?
TIA
