地下室有两盏射灯，经常坏掉，频率大概每个月都要换一次，家里其他各种灯都没有像这样的，不知道是我买的灯有问题还是线路开关的问题？有哪位懂这方面的给指点指点？谢谢！

灯泡的寿命一般900小时， 如果你每天都用8小时， 那大约每四个月就差不多坏掉了

1）supply voltage to your home is too great, bulbs will generally burn brighter and burn out much faster， To find out, use a volt meter and check the voltage in an outlet or at the service panel. Usually you'll like to see a voltage of 115 - 125 volts

2）Another cause of bulbs burning out is excessive fixture vibration. A good example of this is a ceiling fan in your home that also incorporates lighting on the unit. When a fan blade becomes unbalanced, the fan starts to shake.

3）The bulb itself could be the problem. Sometimes, cheaper bulbs will have little or no solder on the contact point of the bulb. These bulbs will cause you problems and wo't last very long.

5）The fixture may have a loose electrical connection, loose contacts, or a damaged contact in the socket base itself. These problems often cause the lamp to run much hotter which could melt the connection solder joints or burn the contacts.
