I'm having a problem with 60-75w household lightbulbs not lasting but about 2 months in my house. I live near the beach but don't know if the salt enviroment adds to the problem. Line voltage reads 115v-117v on the average. I also experience 1 to 2 brown outs a month.
How close are you to the transformer on the power pole? The closer you are the higher the voltage might be. I have a transformer from the power company right outside my house and I get 125-130 volts AC and my bulbs don't last too long. As Elektrikguy said, you might need 130 volt AC bulbs. They will last longer.
