多谢。你装这么多? 请问是6"的吗?每个发多少lumen的光?
你家里recessed light买LED的吗?
今天去看,发现带LED灯的trim, 每个最亮才620 lumens, 而一个普通节能灯都800
lumens了。现在都犹豫要不要用LED recessed light了?如用LED灯,我也担心6个可能
不够亮。9个安排如下: 平行短边: 每个离墙3', 灯间距3.5'. 平行短边: 每个离墙
4', 间距也是4’。 若6个,则几乎等间距4'.
非常感谢。也谢谢其他同学的答复。

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.

Lumen回不回来看编剧了, 当初Lendy走了也可以回来的. 如果最后大结局Dexter金盆

本季的最后安排Debra抓现场和Dexter/Lumen隔幕对峙算是Finale的唯一亮点, 最后庆

皮地亚:
Direct sunlight has a luminous efficacy of about 93 lumens per watt of
radiant flux, higher than most artificial lighting, including fluorescent.
Multiplying the figure of 1050 watts per square metre by 93 lumens per watt
indicates that bright sunlight provides an illuminance of approximately 98
000 lux (lumens per square meter) on a perpendicular surface at sea level.

差别不大
The average efficiency of LEDs stood at around 80 lumens per watt in mid-
2013, but is now closer to 100 lumens per watt, according to the U.S. Energy
Information Administration. That is far higher than the typical efficiency
of CFLs, which ranges from approximately 55 to 70 lumens per watt.

And I just checked it. At 858x600 resolution, it's
indeed not good for professional use (you need
at least 1024x768). At 50 ANSI Lumens,
it's like candle light, comparing with a normal
classroom projector at thousands of Lumens.

来自主题: Living版 - recessed筒灯接电源一问
请教大师。我living room 和family room想装LED recessed lights. 阁楼进不去。都
需要在房间里把天花板打开做。请问买home depot的 halo remodel 筒子行吗?不需要
new construction的吧?
halo 的6"灯(13W,65W equivalent, 640 lumens, 3000K, IC rated, airtight)好
吗? Lithonia lighting (600 lumen, 65W equivalent, 3000K, 5", baffle, IC
rated)的灯更漂亮些,但没有air-tight字样。不知是否还是选halo的更好?
各装6个LED灯(两空间是各221 sq ft, 208 sq ft) 不知是否够了?各装两个dimmer,
每个dimmer 控制3个led 灯。dimmer买Lutron LED dimmer好吗?
当然最后是请师傅做,但我想先把材料买好。非常感谢。
