The life of a filament lamp relates to the applied voltage and if the voltage is lower the life will be much longer. What you could try is to connect two sets of lights together in series, this will make each lamp have only half its intended voltage, obviously the light output will be lower but it might still be enough to see the effects from the bulbs.
In series means - that one wire from the 1st set goes to the live supply, the other wire from the 1st set connects to one wire from the 2nd set and the other wire from the 2nd set goes to the neutral supply.
To be honest, for home use anything which does dimming of the actual voltage levels would be very expensive.
