发帖数: 1422 | 2 邻居家都有outdoor lighting,晚上看着个个挺漂亮。找了个contractor,开价2k. 上
youtube看了看，发现装outdoor lighting不难，决定DIY.
在home depot买了两个Malibu flood light kit(含transformer,4个50w flood lights
和100 yard cable), 总成本小于$400.安装用时4hrs(包括埋线到地下).
费了半天劲装完，领导看后持保留意见。:-( |

发帖数: 3319 | 3 多谢。好能干啊！
真是及时雨，好帖子。紧急请教，你这是多少尺寸的房间，灯具体layout怎么安排？每
个灯多少lumen亮度。几个控制开关？
我想装6个还是9个定不下。13'x16'的空间，
如果6个，我需要网上订灯，800 lumen一个，2700K. 2x3, parallel to 13' wall, 3.
5'(wall to light), 5'(light to light), 4.5' (light to wall, floor has
register at 1' from the wall). Parallel to 16' wall, all 4' apart. 不知这样
行否？不对称主要考虑实用角度。
如果装9个，我大概就local HD 买算了，他们有625 lumen的。
用于living room or family room.
Thank you so much. |

我这么问是因为看到home depot和lowes上卖的recessed light shower kit(含housing

由此引申出的另外一个问题是，在这种潮湿环境下装recessed light,到底是哪部分需

发帖数: 1476 | 8 我是车盲。车版一同学也说可能电池没电。是的，正常启动的话，所有灯都亮了查一下
系统，然后几秒后就灭了。启动不了所有灯都亮着不会灭掉（包括,brake light,
engine oil light, battery light,好像也就这三个light）。
为什么电池会没电呢？难道开车的过程中电池不是自我充电的吗？我今天早上还开车出
去吃早餐，车灯是关着的。现在车灯还是能亮，当然车灯能亮不能说明什么，电池电量
不足时不能启动车但还是有可能支持车灯一段时间。

the same as eos hiking light, but with extra bike mount. Actually I also use
it for hiking, just need to swap out for a head band. For biking, if you
ride in total darkness, I suspect it is not bright enough, and the LED light

你自己读一下吧。人家是在Indian Wells现场做的测量。
你说的pro的拍子是定做的，没错，其实很多Pro racket上面都直接印有他们的名字，
以防搞错（例如下面Ivanovic的拍子）。但是Soderling这个2 pt head light是测
量出的，是铁定的事实。
女选手更喜欢less head light, 她们的拍子基本上跟市面上的完全不一样，通常
重量类似，但是要head heavy的多，也就是高的多的swing weight. 例如Ivanovic

YOU LIGHT UP MY LIFE (Debbie Boone)
So many nights I sit by my window
Waiting for someone to sing me his song
So many dreams I kept deep inside me
Alone in the dark but now
You've come along
You light up my life
You give me hope
To carry on
You light up my days
and fill my nights with song
Rollin' at sea, adrift on the water
Could it be finally I'm turning for home?
Finally, a chance to say hey,
I love You
Never again to be all alone
You light up my life

以前Strobe light的好处就是输出量大，且不会产生很大热量，适合各种softbox等
modifier。
现在的持续光源因为有了低温全光谱节能灯，在亮度已经有了很大进步，温度也不成问
题，但是在瞬间输出亮度还是不如Strobe light。特别是加了柔光箱以后，对亮度损失
比较大。当然好处是容易调节，比较安全，容易直接看布光效果。 |
