Do your light bulbs blow out frequently. There are several reasons this could be occurring. However, one particular reason that should be ruled out, for the sake of fire safety, is overheating. A light fixture with poor airflow design will result in excessive heat buildup around the bulb. Having to replace bulbs again and again is not only an inconvenience, it’s also a fire hazard. The flickering of light bulbs in lamps and fixtures can also be caused by bulbs that have been installed too tightly into light fixtures. Have your light fixtures inspected by an electrician if you notice that bulbs are constantly burning out quickly.
