It's a well know fact that the life span of incandescent light bulbs increases
with lower operating voltage. If I remember it right the lifespan increases by
7 times with a 10% decrease in voltage. I guess a 240V bulb working on 120V
would outlast the life of the radio station. Light efficiency (power in - light
out) is not that good though.
3.5x life if 12th power (e.g. 0.9^12 = 0.28)
