发帖数: 3792 | 3 可以,我就这么做的,但是你要自己先弄清楚走线
我的原来是这样的,
电源线I--东墙开关--A 线经从东墙网上阁楼---西墙插座上插头,所以这个孔受开关控

同时电源线II--西墙插座下插头,所以这个孔不受开关控制,不动这里

放四个recessed light的CAN1,2,3,4
CAN 1 == CAN 2 == CAN3 == CAN4连好,黑线接黑线,白线接白线
然后到阁楼,剪断A线, 黑线接黑线,白线接白线,到CAN 4
这样灯就完工了
但是西墙插座上孔没电了,你可以不理,或者买个新的插座,接上就是,利用电源线II供电
给上插头和下插头
如果是阁楼爬不进的,地方不够的,或者是12楼之间的,要买remodel recessed lighting
can,14刀一个,不然可以买new construction lighting can,7刀一个
只要你能找到那里剪断A线,就可以完成
如果有insulation,你要买insulation contact的lighting can
至于什么功率啥的,如果只接4灯,几乎不需要考虑,一般用什么就什么,应该... 阅读全帖 |

too. It's sad because everyone thinks so, and that makes him think that way
too.
Whenever you compare, it only makes u feel sad, because everyone only looks
up, and rarely looks down. But when you look down, you will be a lot happier.

You compete, you loss, and you think that's not the end of the world, OK.
But if you think you compete, you loss, then it ends..
too bad.
Progress in this world is driven by profits.. |
