"Long Life" bulbs are simply made with a filament suitable for higher voltage.

Life is in proportion to volts^13th power , approximately.

Check with local industry supplier for 250 volt lamps..
Yes, I remember I always put dimmers for lights that is hard to reach, get the 150W bulb and turn it down. They last forever. I don't recall we ever burnt out one yet. I Did it like this until we change to all florescent lights in 1994. They really cut down the electric bill.
