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 (水城百事)

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！ - //// ; 13-07-05,11:07 (#196531) Reply (水城百事)
- 不会这么频繁，估计线路有问题 - 找人看看 ; 13-07-05,11:10 (#196539) Reply
  - 我也怀疑是线路问题。。。可是也不认识什么懂这方面的人，真麻烦啊，都换了好多个灯了 - //// ; 13-07-05,11:41 (#196564) Reply
    - 如果你用的是普通开关,灯炮本身的问题是主因,如果用特殊开关,就要考虑开关的问题.别的方面大多是小概率事件.可能你家还有比较特别的情况,可以电话详谈.我的电话,5197295360. 我有建筑电工牌. - bigben_hometech ; 13-07-05,21:51 (#196808) Reply
      - 质量差点的灯泡有时只有300小时寿命.所以你一个多月换次灯泡还是有这种可能的. - bigben_hometech ; 13-07-05,22:11 (#196820) Reply
      - 非常感谢！已经记下了您的联系方式。暂时我考虑还是先不麻烦你了，我想试试换了牌子的灯泡，如果情况好转那就是灯泡问题了。日后如果有其他不能解决的问题，我会联系您的。 - //// ; 13-07-06,11:53 (#196865) Reply
  - 我的体会是有些牌子的灯泡寿命长一点。我家builder给的那些灯泡很少坏，现在都11年了，还剩下一大半在那里。另外如果你的等需要频繁开关，不要使用节能灯 - max ; 13-07-05,22:20 (#196823) Reply
- 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 - andrew ; 13-07-05,11:58 (#196573) Reply

    - 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. - andrew ; 13-07-05,12:01 (#196576) Reply

    - 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. - andrew ; 13-07-05,12:03 (#196578) Reply

    - 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. - andrew ; 13-07-05,12:11 (#196584) Reply
    - 多谢详细的答疑解惑！地下室因为光线不够，射灯确实点的时间很长，远远超过8h/天，基本上除了睡觉的时候不点，其他时候都是亮着的。线路问题自己不太会查，不懂电不敢乱动，下回试试买贵一点的灯泡看看会不会用的久一点。再谢！ - //// ; 13-07-05,14:05 (#196646) Reply

- 肯定是射灯本身的问题,跟线路没关 - ipad ; 13-07-05,19:55 (#196776) Reply
  - 也不知道哪个牌子的质量比较好，买东西跟抓阄一样，家里存货用完了，去买最贵的试试 - //// ; 13-07-05,19:57 (#196779) Reply
  - 我们家地下室射灯也坏掉好几个，而且我们不常用，准备特价的时候买一些 - 喜羊羊 ; 13-07-05,21:51 (#196809) Reply
    - 别买普通射灯了,又耗电又短命.买LED的射灯吧.贵会贵点,但会在电费及寿命上面省下来的. - bigben_hometech ; 13-07-05,22:06 (#196816) Reply

        LED射灯包装盒上一定会有LED字样,就像LED电视机一定会区别出来一样.厂家不会放过这个亮点吧. - bigben_hometech ; 13-07-05,22:19 (#196822) Reply
