Does anyone know where I can buy 'normal' filament lamp bulbs in the UK
please? I just cannot get on with the new economy type. My remaining stock
of 60W and 100W is dwindling rapidly.

The vast majority of failures occur at switch on due to the surge current at
that instant, some TVs, monitors and other switch mode power supplies have a
negative temperature coefficient thermistor in series with the fuse to limit
turn on surge - a salvaged NTC thermistor grafted into behind the switch
plate with an insulated connector block will substantially increase the life
expectancy of filament bulbs.

No it won't. A worn out filament may well fail during a turn on surge.

Avoiding the surge can only delay the inevitable for a short time.

A significant life expectancy increase can only come from avoiding
something that wears out the filament and turn on surges don't.
