Why do my light bulbs burn out so quickly?

Answer: You may be exceeding the maximum lamp wattage of the fixture. There should be a label inside the fixture. If the label is not there consider replacing the fixture. Do not exceed 60 watts for most ceiling fixtures. Many times vibration is the culprit in short bulb life. There are vibration resistant bulbs for ceiling fans and garage door openers and there are rough service bulbs for portable lights. Sometimes a porch light can have a shortened life due to a slamming door. A rough service bulb would do well in such a location. Sometimes there is more than 120 volts being brought into the light socket. You can purchase a 130 volt light bulb to take care of this problem.
